Schematic illustration of the participation of select tumor suppressor genes (p21, Ink4a, and Arf) and an EMT factor (Snail1) in the amenability of HPC/HSC reprogramming. Select tumor suppressor and mesenchymal genes were downregulated in HPC/HSCs and select oncogenes were upregulated in HPC/HSCs compared with MEFs, indicating that these genes may play important roles in the reprogramming of HPC/HSCs. The downregulation of tumor suppressor genes (p21, Ink4a, and Arf) and Snail1 in HPC/HSCs triggers the amenability of HPC/HSCs to OSKM-mediated reprogramming. Independent ectopic activation of p21, Ink4a, Arf, and Snail1 along with OSKM decreases the efficiency of HPC/HSC reprogramming.
