Advances in the Study of Pluripotent Stem Cells in Livestock

Cell Proliferation, EarlyView.
Livestock pluripotent stem cells include embryonic stem cells (ESCs) isolated from the inner cell mass of blastocysts and induced pluripotent stem cells (iPSCs) derived from somatic cell reprogramming. They hold significant potential for applications in livestock breed improvement, rapid propagation, human disease modelling and human organ ...

RNF187 Facilitates Proliferation and Migration of Human Spermatogonial Stem Cells Through WDR77 Polyubiquitination

Cell Proliferation, EarlyView.
RNF187 mediates the polyubiquitination and subsequent degradation of WDR77, reduces H4R3me2s catalysed by the WDR77/PRMT5 complex, and derepresses the transcription of EGR1, thereby promoting the proliferation and migration of human SSCs. ABSTRACT The E3 ubiquitin ligase RNF187, also known as RING domain AP1 coactivator‐1, is a member of the RING ...
