The laboratory

A cure for diabetes is a manufacturing problem now, as much as a biology problem.

The science of making insulin-producing cells from stem cells works. What has lagged behind is producing them at the quantity, consistency and cost required to treat millions of people.

The Dadheech Stem Cell Islet Bioengineering Laboratory sits at that gap. We integrate human pluripotent stem cell biology, islet bioengineering, cell therapy and translational manufacturing to generate functional, mature human islets that can be transplanted without a lifetime of immunosuppression.

Our core platform is a full-suspension, six-stage differentiation process that runs entirely inside PBS Vertical-Wheel bioreactors — no plates, no manual aggregation, no scale-out. It has produced islets that reverse diabetes in preclinical models using cells from healthy donors, pancreatectomy patients and people living with type 1 diabetes.

Around that platform we build the rest of what a therapy needs: immune-tolerant cell products, a vascularized graft site, quality systems that hold up to regulatory scrutiny, and the genomics to understand why any individual patient's cells behave the way they do.

Programs

Four problems, worked in parallel

Each of these is a genuine barrier between where SC-islet therapy is today and a treatment a person can actually receive. We work them together because solving any one alone does not produce a therapy.

Program 01

Autologous islet bioengineering

Reprogramming patient cells into GMP-compliant, stable iPSC lines and differentiating them to mature, glucose-responsive islets — a product matched to the person who receives it.

Program 02

Immune tolerance without drugs

Genomic engineering and personalized cell sourcing to build islet products that survive without chronic immunosuppression, the single largest barrier to treating anyone but the sickest patients.

Program 03

Vascularization and the graft niche

Co-manufactured islet-specific endothelial cells, ECM-derived interfaces and engineered transplant sites, so grafts get the oxygen and blood supply they need to survive the first two weeks.

Program 04

Genomics of islet failure

Single-cell and spatial transcriptomics across type 1 and type 2 donor-derived iPSC lines to resolve the heterogeneity nobody can currently explain — and to predict which lines will make good islets.

Research & Technology

What has to be true before a stem cell islet becomes a therapy

Four requirements: enough cells, cells that survive, cells the immune system tolerates, and a way to know in advance whether a given patient's cells will work. Our research program is organized around those four, and the manufacturing platform underneath all of them.

Program 01

Autologous iPSC-derived islet bioengineering

A patient's own cells, reprogrammed, differentiated and returned as functioning islets.

Allogeneic islet products work, but they commit the recipient to immunosuppression for life. An autologous product removes that trade-off at the source — if you can make it reliably, from any donor, at clinical scale.

We generate GMP-compliant, karyotypically stable iPSC lines from patient somatic cells and drive them through a six-stage, fully suspended differentiation to mature SC-islets. Our published platform has done this with lines from healthy donors, from pancreatectomy patients, and from people living with type 1 diabetes, with diabetes reversal demonstrated preclinically across all three.

  • Matrix-free 3D reprogramming directly in Vertical-Wheel suspension, removing feeder layers and coated plates from the front of the process
  • Line-to-line variability characterized rather than averaged away, so that donor heterogeneity becomes a measurable process input
  • Deep-learning prediction of reprogramming success from early morphology, to cut failed lines before they consume a manufacturing slot

Program 02

Immune tolerance and hypoimmune engineering

The goal is a graft that lasts without immunosuppression — not one that lasts because the recipient is immunosuppressed.

Chronic immunosuppression is why islet transplantation, which works, is offered to only a few hundred people a year. It carries infection risk, malignancy risk and renal toxicity that most people with diabetes should not be asked to accept.

We pursue two routes in parallel. Autologous sourcing removes the allogeneic barrier but leaves autoimmune recurrence in type 1 diabetes intact. Genomic engineering of the islet product addresses both — modifying the cells so they are not seen by the immune system, and stress-hardening them against the inflammatory environment of the transplant site.

  • Hypoimmune edits engineered into the iPSC line before differentiation, so every cell in the product carries them
  • Autoimmune-recurrence modelling in patient-derived T1D lines, where the original disease process is still encoded in the genome
  • Regulatory T cell and tolerogenic strategies developed with our transplantation collaborators
Endocrine composition · immunohistochemistryA stage 6 aggregate resolved by marker. The proportion and spatial arrangement of hormone-positive cells is a release-relevant attribute, not a cosmetic one — it predicts how the graft behaves in vivo.

Program 03

Vascularization and the transplant niche

Most transplanted islets die in the first two weeks, before a blood supply ever reaches them.

A native islet is one of the most densely vascularized tissues in the body. A transplanted one arrives with no vasculature at all and has to survive on diffusion until the host grows vessels into it — a process that takes longer than the cells can tolerate.

We attack this from both sides. On the product side, we co-manufacture islet-specific vascular endothelial cells alongside the islets in the same bioreactor run, so the graft carries the beginnings of its own vascular network. On the recipient side, we engineer the transplant site itself, using ECM-derived interfaces and prevascularized niches that are ready to perfuse the graft on arrival.

Program 04

Genomics of β-cell failure and line heterogeneity

Two iPSC lines that look identical can produce completely different islets. We want to know why before we spend a manufacturing run finding out.

We run integrated human genetics and genomics screening on iPSC lines derived from people with type 1 and type 2 diabetes, comparing them against healthy donor lines and against primary human islets. Single-cell RNA sequencing, spatial transcriptomics and multi-omics let us resolve the heterogeneity that bulk measurements average out.

The near-term goal is practical: identify the molecular signatures that predict differentiation competence, so line selection stops being empirical. The longer-term goal is mechanistic — defining how islet dysfunction, immune-mediated vulnerability and β-cell death actually proceed in each form of diabetes.

Technology

Platform and instrumentation

The equipment is chosen so that a process developed at bench scale transfers to a clinical run without being redesigned.

Bioprocess

PBS Vertical-Wheel bioreactors

Development vessels through production scale, all sharing one impeller geometry. Low-shear, uniform mixing that keeps aggregates in a narrow size distribution — the property that makes suspension differentiation reproducible, and the reason a process moves between volumes intact.

Containment

BioSpherix X2 closed system

Hypoxia-capable, fully closed cell handling under continuous atmospheric control. Cells are never exposed to room air or room oxygen tension between process steps.

Spatial omics

MERSCOPE Ultra

Single-molecule spatial transcriptomics on intact islets and graft sections, mapping identity and stress states to position within the aggregate.

Function

Dynamic perifusion & GSIS

Glucose-stimulated insulin secretion with first- and second-phase resolution, benchmarked against primary human donor islets rather than against other stem cell products.

Imaging

Leica THUNDER Imager DMi8

Whole-slide scanning and volumetric imaging of intact islets. Computational clearing removes out-of-focus haze without a confocal pinhole, so a whole aggregate can be resolved in three dimensions rather than sampled one plane at a time.

Imaging

High-content ICC

Marker-resolved characterization of endocrine composition, architecture and off-target populations across every differentiation stage.

Computation

Deep learning for reprogramming

GMP Manufacturing Unit  ·  SUNY Upstate Medical University, Syracuse NY

The GMP manufacturing suiteDr. Dadheech in the unit. The X2 chamber train runs the length of the room; the control station at left carries live process values for every chamber.

Making one dose is research. Making the thousandth dose the same way is the therapy. This unit exists to close the distance between a differentiation protocol that works on a good day and a process that produces a defined, releasable product every time it runs.

The core capability

A 3 L bioreactor running inside a closed GMP chamber

BioSpherix X2 GMP  ·  PBS-3 Vertical-Wheel under containment

This is the part of the facility that is genuinely unusual. Most groups run their bioreactor on an open bench and move product in and out through a biosafety cabinet. We put the vessel inside the containment.

BioSpherix X2 — closed manufacturing unit

The X2 is a linked train of sealed chambers. Incubation, processing, sampling and transfer each have their own chamber, joined by pass-through ports, and every manipulation happens through glove ports. Product never sees room air and never sees room oxygen tension.

Oxygen, carbon dioxide, chamber pressure, volatile organics, 0.5 µm particle count and temperature are each held to setpoint, alarmed, and logged continuously against the batch record. The atmosphere becomes a controlled process parameter rather than whatever the room happened to be that day.

PBS-3 Vertical-Wheel, integrated under containment

The 3 L Vertical-Wheel bioreactor is installed inside the X2 envelope rather than beside it. Feeds, samples and the final harvest all happen without ever breaching the closed system, which removes the open manipulations that are normally the highest-risk steps in a cell therapy run.

It also means the process does not have to be redesigned on the way to clinical scale. The same closed handling that governs a 0.1 L development run governs a 3 L production run.

Scale

0.1 L → 0.5 L → 3 L

Scale-up, not scale-out  ·  one impeller geometry at every volume

The Vertical-Wheel geometry is the same in every vessel in the range. Shear stays low, mixing stays uniform, and aggregate size distribution holds as volume increases — which is why a process transfers between vessels instead of having to be re-developed at each scale.

1.8–3.0 L working volume with full bioprocess control and monitoring, installed inside the BioSpherix X2 closed chamber. The volume at which a single autologous patient dose becomes practical.

Vessels are drawn to scale by volume. The Vertical-Wheel range continues to 15 L and 80 L on the same geometry, so the ceiling above 3 L is a question of demand rather than of process redesign.

The platform

Full suspension, start to finish

Every stage — from undifferentiated iPSC expansion through to mature SC-islet — runs in suspension in the same vessel type.

Conventional protocols begin in adherent 2D culture and hand off to 3D somewhere in the middle. Each handoff is a manual step, an open manipulation, a source of variability and a place where the process cannot simply be made bigger.

Removing 2D culture entirely removes those handoffs. It also removes coated plates, feeder layers and manual aggregation from the bill of materials, which matters when every raw material has to be qualified for clinical use.

  • No adherent culture, no manual aggregation, no plate-to-vessel transfer
  • Aggregate formation controlled by agitation and seeding density rather than by microwell geometry
  • Closed transfers between stages under continuous atmospheric control
  • Scale-up by vessel volume, not by running more vessels in parallel
Stage 6 harvest · brightfieldIslets from a suspension run, unsorted and unsized. The narrow diameter distribution is a direct consequence of the vessel hydrodynamics and is one of the process attributes we control to.

Daily practice

What a run actually looks like

A differentiation is not one event. It is weeks of feeding, sampling, checking and recording, done the same way every time by people who are gowned before they touch anything.

Feeding and samplingMedia exchange inside the cabinet. Volumes, timings and the order of operations are fixed by SOP, because the difference between runs has to come from the biology and not the hands.
Daily check on the scopeAggregates are inspected at every stage. Size distribution, edge definition and clumping are early signals — long before an assay would tell you the run had drifted.
In and out of the incubatorTime out of controlled atmosphere is time the cells spend somewhere they should not be. Transfers are planned so that plates are handled once, not repeatedly.
Two sets of handsCritical steps are run in pairs — one working, one reading back the record. It slows an individual step and saves whole runs.
The oldest test there isHolding the vessel up to the light. Turbidity, colour and contamination announce themselves to the naked eye before any instrument is involved.
At the glove portsEverything inside the closed system is reached through the gloves. It is slower than an open bench, and it is the reason the product never meets room air.

Quality and control strategy

Built to a design space, not to a recipe

We develop the process under Quality-by-Design principles aligned to ICH Q8–Q11, defining which parameters actually move product quality and how far each one can move before it does.

Identity check on a released batchInsulin (green), glucagon (red), nuclei (blue). Endocrine composition is measured on every run, not sampled occasionally — it is the attribute that connects what happens in the vessel to what happens after transplant.

Documentation and traceability

Runs are executed against controlled, versioned SOPs with in-process checks recorded at each stage transition. The laboratory maintains an electronic laboratory notebook with inventory, sample repository and assay modules, so that every vessel, reagent lot and result is traceable to a single manufacturing record.

Mehmet Zeynel Cilek, PhD

Translational scientist · two decades in stem cell biology, regenerative medicine, gene therapy and bioengineering

Dr. Cilek develops scalable, personalized stem cell-derived islet therapies for diabetes and moves them toward clinical translation. He leads the laboratory's programs in iPSC-derived islet manufacturing and process development, combining developmental biology, genomics, 3D culture and bioprocess engineering into reproducible platforms for making functional, glucose-responsive islet cells.

A central achievement of his work is a hybrid 2D/3D differentiation platform built around Vertical-Wheel bioreactor technology. It addresses the limitations that conventional culture systems run into at scale, and it is the route to consistent, high-quality islet manufacturing at clinically relevant volumes.

His current research spans genomically guided islet differentiation, automated GMP-compatible manufacturing, and transplantation strategies designed to improve graft survival and function — together, an integrated pipeline carrying patient-specific iPSC-derived islets from laboratory development toward therapeutic use.

He has served as Principal Investigator or contributing researcher on 27 research grants totalling more than $25 million, and is committed to mentoring the next generation of scientists and building the multidisciplinary teams that get cell therapies to patients.

    Positions we argue for

    Scale-up beats scale-out

    Running a hundred small vessels in parallel does not produce a scalable therapy. Process intensification within a single unit operation does.

    3D is not an upgrade to 2D — it is a different process

    Suspension culture changes iPSC phenotype, differentiation trajectory and product identity. It should be developed as its own platform, not retrofitted.

    Immunosuppression is the ceiling

    Until the graft survives without it, cell therapy for diabetes stays limited to the small group of patients sick enough to justify the trade.

    Awards & Honors

    Recognition for the work and the people doing it

    Prizes are not the point of the research, but they are a fair signal that people outside the laboratory find the work credible.

    The award followed the development of the full-suspension Vertical-Wheel platform for stem cell-derived islet manufacturing — the work that established that iPSC differentiation could be run end to end in a bioreactor and still yield islets with the endocrine composition, secretory capacity and diabetes-reversal potential of primary donor tissue.

    It is the platform the Dadheech Laboratory at SUNY Upstate is now built on.

    Congratulations

    Best Oral Presentation

    Dr. Zeynel Cilek · Department of Medicine Research Retreat 2026

    Our Cell Therapy and Process Development Team Lead took the Best Oral Presentation award at the Department of Medicine Research Retreat.

    The talk covered the laboratory's suspension differentiation platform and the process work behind it — the part of this field that rarely gets a podium, and the part that decides whether any of it reaches a patient.

    Join Us

    Come build the manufacturing science for a diabetes cure

    We are a new laboratory. That means the platform is already working, the problems are already defined — and there is a great deal of room for people who want to own a piece of it.

    We are looking for cell culture specialists, postdoctoral fellows and graduate students with an interest in human pluripotent stem cell biology and pancreatic differentiation or regeneration. Prior islet experience is welcome but not required; disciplined aseptic technique and genuine curiosity are.

    What working here looks like

    • Hands on a real manufacturing platform, not a model system — Vertical-Wheel bioreactors, closed-system handling, controlled SOPs
    • Projects that run from cell biology through to process parameters and regulatory strategy
    • Co-authorship and conference presentation as the default, not the exception
    • A collaborative network spanning Alberta, Louisville, and industry partners in bioprocess engineering
    • Mentorship structured around where you want to end up, whether that is academia, industry or clinical translation

    Open positions

    Current openings

    Postdoctoral Fellow

    Open

    Lead a project in one of: SC-islet differentiation and maturation; suspension bioprocess development and scale-up; islet vascularization and endothelial co-culture; or single-cell and spatial genomics of iPSC-derived islets.

    You bring: PhD in stem cell biology, bioengineering, cell biology or a related field; hands-on hPSC culture; a first-author publication record.

    Cell Culture Specialist / Research Technician

    Open

    Day-to-day iPSC maintenance and suspension culture, bioreactor setup and operation, sample processing, flow cytometry and immunostaining, and SOP-driven record keeping.

    You bring: BSc or MSc with strong aseptic technique and mammalian cell culture experience. Bioreactor or GMP exposure is a plus.

    PhD Students

    Rotations welcome

    Admitted through the SUNY Upstate College of Graduate Studies. Rotation projects are available in differentiation biology, bioprocess engineering and islet genomics.

    Apply through: the College of Graduate Studies or the Department of Pharmacology PhD programme, then contact Dr. Dadheech directly.

    Undergraduate & Summer Research

    By arrangement

    Support our research

    Together we can deliver a cure

    A person with type 1 diabetes makes several hundred decisions a day that a working pancreas would have made for them. We are building the thing that takes those decisions back.

    The biology is no longer the hard part. Stem cells can be turned into insulin-producing islets, and those islets reverse diabetes in preclinical models. What stands between that result and a treatment someone can receive is manufacturing science, immune tolerance and the years of unglamorous work in between.

    That work is what your support pays for.

    Funding

    We are funded from

    Department of Medicine

    SUNY Upstate Medical University · Start-Up Grant

    The award that established the laboratory. It bought the bioreactors, the closed-system chambers, the first reagents and the first people. Start-up funding is finite, and it is spent standing a laboratory up rather than running it indefinitely.

    SUNY Research Foundation

    The Research Foundation for The State University of New York

    The Research Foundation administers sponsored research funding for SUNY Upstate, and holds and manages the laboratory's research accounts.

    Philanthropy sits alongside these. It is the most flexible money in the laboratory, and per dollar it moves the science furthest — because it is the only funding that can be spent on an idea before that idea has proved itself.

    Impact

    What a gift pays for that a grant will not

    Grant budgets are written a year or more before the money arrives, against aims already defended in review. Research does not always wait for that cycle.

    • Preliminary data. The pilot run behind a new idea, before there is any evidence to put in an application
    • An additional patient-derived line. Every donor line we characterize sharpens our picture of why some cells make good islets and others do not
    • Continuity for people. Keeping a technician or trainee on staff through a gap between awards, so expertise does not walk out of the building
    • A run that might fail. Bioreactor time and consumables for an experiment with real risk attached, which is where the useful answers usually are
    • Trainees at the podium. Sending a student to present their own work at a national meeting
    • Instrument capability. Closing the gap on a piece of equipment the programme needs sooner than a grant cycle will deliver it
