Generation of Induced Pluripotent Stem Cells from Erythroid Progenitor Cells.

Induced pluripotent stem cells (iPSCs) are generated through the reprogramming of somatic cells to an embryonic-like state by activating specific genes. They closely resemble embryonic stem cells (ESCs), in various aspects, including the expression of key stem cell genes, potency, and differentiation capabilities. iPSCs can be derived from various cell types such as fibroblasts, keratinocytes, and peripheral blood mononuclear cells (PBMCs). The ease of obtaining origin cells through non-invasive methods simplifies the generation of human iPSCs. Therefore, PBMCs are commonly preferred, with erythroid progenitor cells (EPCs) obtained through EPC enrichment being used as origin cells in this protocol. The EPC enrichment performed in this protocol not only reduces costs but also increases efficiency by enhancing the percentage of reprogrammable cells with progenitor characteristics. Human iPSCs are incredibly valuable for in vitro research, cell therapy, drug discovery, and tissue engineering. The outlined procedures below provide a general framework for inducing iPSCs from erythroid progenitor cells, pluripotency confirmation experiments, and cultivating them for downstream experiments.
