Clinical iPSC Production Workflow at Seed Clone Stage

Why choose REPROCELL for your clinical iPSC program?
REPROCELL provides an integrated clinical iPSC workflow supporting cell therapy development from early evaluation to GMP manufacturing. The process starts with fibroblast isolated from screened, clinically consented donors, then reprogrammed using our proprietary footprint-free StemRNA™ Clinical RNA Reprogramming Technology. HLA and KIR (Killer-cell immunoglobulin-like receptors) genotyping data are available for every donor. Multiple iPSC clones are generated and characterized to produce GMP-compatible seed clones for clinical programs and corresponding research-use pilot clones. This approach enables efficient clone selection and a seamless transition into downstream applications such as StemEdit Gene Editing or GMP Master Cell Bank (MCB) production providing a consistent, regulatory-aligned starting point for clinical cell therapy manufacturing.

Choose the right starting point for your iPSC program
1. Exclusive StemRNA Clinical Seed Clones
Tailored iPSC generation from clinically consented donors, aligned with your therapeutic strategy and regulatory requirements. You can provide the clinical fibroblasts, or we can collect, screen, and isolate the fibroblasts for you.
2. Our bank of StemRNA Clinical Seed Clones
Tap into our bank of pre-generated clinical clones. Many StemRNA Clinical iPSC Seed Clones also have a corresponding RUO version (StemRNA Clinical iPSC Pilot Clones) for research evaluation.
3. GMP MCB Manufacturing Service
Submit your clinical clone for GMP-compliant MCB manufacturing. Clones are expanded and banked under GMP conditions creating well-characterized, traceable starting material for downstream development and ensuring consistent, regulatory-ready quality.
What is the difference between
ready-to-use Seed and Pilot Clones?

StemRNA Clinical iPSC Seed Clones (Clinical-use)
StemRNA™ Clinical iPSC Seed Clones are designed as the clinical starting material for cell therapy development. Produced under GMP principles and with comprehensive quality control (QC), they enable the generation of GMP Master and Working Cell Banks (MCB/WCB) for regulated downstream manufacturing.
- Manufactured at REPROCELL USA or REPROCELL Japan GMP facility
- Compliant with US FDA, European EMA, and Japanese PMDA regulations
- Ready for GMP MCB and working cell bank (WCB) manufacturing
- Included in regulatory filings, INTERACT meetings and IND submissions
- Active FDA Drug Master File (DMF) for all U.S.-manufactured clones
- Advanced into US FDA Phase 3 clinical trial
- OncoPanel genetic integrity report for every seed clone and fibroblast line
- Straightforward commercial & licensing structure
- Different clonal lines have been validated for their differentiation potential into various specific cell types, as proof of principle. This includes: HSCs (hematopoietic stem cells), NSCs (neural stem cells), NK (Natural Killer) cells, astrocytes, iGRPs (induced glia-restricted progenitors), iMSC (iPSC-derived Mesenchymal Stem Cells), and others.
- New differentiation data are regularly added, making it easier to select the best clonal line for your therapeutic project.

StemRNA Clinical iPSC Pilot Clones (Research-use)
These are research-grade pilot clones derived from our clinical seed clone platform. Intended for evaluation and process development only, they provide a cost-effective way to test, optimize and validate workflows before moving to a clinical seed clone.
Both the Seed Clones and the Pilot Clones include an evaluation period to determine their suitability for your process. During the evaluation period, sufficient vials of the Seed Clones will be reserved for you to carry forth into GMP iPSC Master Cell Bank generation after successful evaluation.

News & Regulatory Feedback
One of REPROCELL’s StemRNA™ Clinical iPSC Seed Clones (from Donor B, Female 23 yo, Caucasian, Healthy A+) enabled a historic breakthrough in assisted reproduction: Gameto’s Fertilo platform achieved the world’s first live birth using ovarian support cells fully derived from our clinical-grade iPSCs.
These ovarian support cells closely mirror the natural ovarian environment, allowing in vitro oocyte maturation with minimal hormonal intervention, reducing patient burden and potential complications such as ovarian hyperstimulation syndrome.
An IND was offcially approved by the U.S. Food and Drug Administration, allowing launch of the first-ever Phase 3 iPSC-based therapy trial in the United States, marking the first human iPSC-derived cell application in IVF, redefining cell-based fertility therapy possibilities.
