Comparative methylation profiles and telomerase biology of mouse multipotent adult germline stem cells and embryonic stem cells.

2009

Recently, several groups described the isolation of mouse spermatogonial stem cells (SSCs) and their potential to develop to embryonic stem cell (ESC)-like cells, so-called multipotent germline stem cells (mGSCs). We were the first to derive such mGSCs from SSCs isolated from adult mouse testis and, therefore, called these mGSCs multipotent adult germline stem cells (maGSCs). Here, we compara- tively analyzed gene-specific and global DNA methylation profiles as well as the telomerase biology of several maGSC and male ESC lines. We show that undifferentiated maGSCs are very similar to undifferentiated male ESCs with regard to global DNA methylation, methylation of pluripotency marker gene lo…
