Reprogramming Somatic Cells via TAT-Mediated Protein Transduction: A Promising Approach for Safe and Efficient iPSC Gene

This study explores the potential of TAT-mediated protein transduction in reprogramming somatic cells to induced pluripotent stem cells (iPSCs). The use of TAT fusion proteins successfully delivers recombinant factors for efficient iPSC generation, offering a safer and faster alternative to current protocols. The findings provide significant insights into the development of clinically useful and genetic material-free human iPSCs.
