Abstract

Somatic cells can be transformed into induced pluripotent stem cells (iPSCs) using a technique called reprogramming. This process involves introducing Yamanaka factors (Oct4, Sox2, Klf4, and c-Myc) to the cells through retroviral supernatants. This chapter outlines a protocol for reprogramming mouse embryonic fibroblasts (MEFs) using the hormone triiodo-L-thyronine (T3) to enhance the generation of iPSCs. It also describes how to analyze these iPSCs by colony staining for alkaline phosphatase activity, a standard marker for identifying pluripotent embryonic stem cells. To further study iPSCs, individual colonies must be selected and expanded, and pluripotency is examined by analyzing gene expression profiles using quantitative real-time PCR to measure the endogenous expression of pluripotency genes. Integrating T3 into reprogramming methods may significantly improve the production of functional iPSCs. This advancement could open new avenues for research in cell plasticity, disease modeling, and regenerative therapies.
