Abstract：
:Human pluripotent stem cells (PSCs) are critical in vitro tools for understanding mechanisms that regulate lineage differentiation in the human embryo as well as a potentially unlimited supply of stem cells for regenerative medicine. Pluripotent human and mouse embryonic stem cells (ESCs) derived from the inner cell mass of blastocysts share a similar transcription factor network to maintain pluripotency and self-renewal, yet there are considerable molecular differences reflecting the diverse environments in which mouse and human ESCs are derived. In the current study we evaluated the role of Protein arginine methyltransferase 5 (PRMT5) in human ESC (hESC) self-renewal and pluripotency given its critical role in safeguarding mouse ESC pluripotency. Unlike the mouse, we discovered that PRMT5 has no role in hESC pluripotency. Using microarray analysis we discovered that a significant depletion in PRMT5 RNA and protein from hESCs changed the expression of only 78 genes, with the majority being repressed. Functionally, we discovered that depletion of PRMT5 had no effect on expression of OCT4, NANOG or SOX2, and did not prevent teratoma formation. Instead, we show that PRMT5 functions in hESCs to regulate proliferation in the self-renewing state by regulating the fraction of cells in Gap 1 (G1) of the cell cycle and increasing expression of the G1 cell cycle inhibitor P57. Taken together our data unveils a distinct role for PRMT5 in hESCs and identifies P57 as new target.
