ABSTRACT
Differentiated cells can be reprogrammed into induced pluripotent stem cells (iPSCs) by overexpressing defined transcription factors. The process of reprogramming requires the interaction of various transcription factors to regulate the transformation of cell fate. Hoxd12 (Homeobox D12) is one of the transcription factors regulating the embryonic development of vertebrates, and it plays an outstanding role in the development of the limb, body axis formation, and cell signal transduction. However, any roles of Hoxd12 may play in the somatic cell reprogramming and the pluripotency of embryonic stem cells (ESCs) have not been reported. In this study, we firstly used 7 factors (Sall4-Esrrb-Jdp2-Glis1-Mkk6-Nanog-Kdm2b) and Yamanaka factors (Oct4-Klf4-Sox2) as the research model, combined with RNA interference (shRNA) and gene overexpression, to explore the mechanism of Hoxd12 in somatic cell reprogramming. Moreover, we used CRISPR/Cas9 gene editing to construct Hoxd12 knockout embryonic stem cell lines, and combined embryoid body formation (EB) and RNA sequencing (RNA-seq) to explore the function of Hoxd12 in the pluripotency of ESCs. The conclusions are as follows (1) Knocking down of Hoxd12 inhibits 7 factor-induced reprogramming (
