iPSC Generation from Patient Samples
Our scientists have extensive experience using patient-specific PBMCs or fibroblasts to generate induced pluripotent stem cell (iPSC) lines. We have perfected both footprint-free (episomal, mRNA and other methods) and retroviral reprogramming methods for iPSC generation.
The advantages of using our footprint-free Custom iPSC Generation Service:
Highly efficient reprogramming (0.2%-0.5%)
High quality and purity iPSCs
Footprint-free reprogramming of patient-derived samples: PBMCs (blood)/ fibroblast
Well-optimized feeder/ feeder-free protocols
Suitable for drug discovery and cell therapy applications

CASE STUDY – Patient derived iPSC Generation
ASC has successfully generated iPSCs from several disease specific patient samples. Here is one such project:
Case Study: Generation of Human iPSCs from Patient-derived Skin Fibroblasts
Goal: To generate an iPSC line from patient derived dermal fibroblasts.
The dermal fibroblasts were obtained by skin biopsy from a patient with a rare disorder. The fibroblasts were plated, transfected via electroporation and cultured with ASC’s proprietary iPSC generation media until iPSC colonies appeared. Five high quality candidate colonies were expanded and characterized by immunocytochemical staining using primary antibodies for: OCT4, SOX2, SSEA4, TRA-1-60 and TRA-1-81) and alkaline phosphatase staining. All five clones stained positive for various pluripotency markers tests as well as for alkaline phosphatase (Figure1).
Figure 1.Human iPSCs were generated from patient-derived dermal fibroblasts, using feeder-free, proprietary protocols. The reprogrammed iPSC clones were characterized by pluripotency marker staining for OCT4, SOX2, SSEA4, TRA-1-60, TRA-1-81, and alkaline phosphatase (AP).
