Transgene-Free Cynomolgus Monkey iPSCs Generated under Chemically Defined Conditions

Area of Science:

• Stem Cell Biology
• Translational Medicine
• Non-human Primate Models

Background:

• Non-human primates (NHPs) are crucial for preclinical testing of cell replacement therapies.
• Generating high-quality NHP induced pluripotent stem cells (iPSCs) is essential for allogeneic transplantation studies.
• Existing NHP iPSC lines need expansion for broader translational applications.

Purpose of the Study:

• To generate and characterize novel transgene- and feeder-free cynomolgus monkey iPSCs (Cyno-iPSCs).
• To establish a reliable NHP iPSC resource for preclinical research and cell therapy development.
• To demonstrate the differentiation potential of Cyno-iPSCs into clinically relevant cell types.

Main Methods:

• Generation of cynomolgus monkey iPSCs using a refined protocol.
• Characterization of Cyno-iPSCs for pluripotency markers and quality.
• Differentiation assays to assess cardiomyocyte and neuron generation from Cyno-iPSCs.

Main Results:

• Successfully generated transgene- and feeder-free Cyno-iPSCs from *Macaca fascicularis*.
• Confirmed pluripotency and quality of the novel Cyno-iPSC lines.
• Demonstrated successful differentiation into cardiomyocytes and neurons.

Conclusions:

• Novel Cyno-iPSCs provide a valuable resource for preclinical research in regenerative medicine.
• These iPSCs are suitable for allogeneic transplantation studies in NHPs, mirroring human applications.
• Expansion of NHP iPSC models facilitates the translation of cell-based therapies.
