Transcriptome analysis of testis in response to silencing of Piwi2 sheds light on spermatogenesis in the mud crab Scylla paramamosain by Tao Wang, Li Lu, Fang Liu, An Liu, Haihui Ye

“…In response to the prolonged down-regulation of Sp-Piwi2, the number of germ cells in the testis was markedly decreased. Transcriptome analysis further suggested that Sp-Piwi2 presumably regulates spermatogenesis by promoting spermatogonia proliferation and the differentiation of spermatogonia to spermatocytes, and is also involved in apoptosis and regulation of transposons. …”

Novel Action of FSH on Stem Cells in Adult Mammalian Ovary Induces Postnatal Oogenesis and Primordial Follicle Assembly by Deepa Bhartiya, Seema Parte, Hiren Patel, Kalpana Sriraman, Kusum Zaveri, Indira Hinduja

“…Stem cells comprise two distinct populations including spherical, very small embryonic-like stem cells (VSELs which express nuclear OCT-4 and other pluripotent and primordial germ cells specific markers) and slightly bigger ovarian germ stem cells (OGSCs with cytoplasmic OCT-4 which are equivalent to spermatogonial stem cells in the testes). …”

The male germ unit association is independently regulated of GUM in Arabidopsis thaliana by Abdur Rauf, Anbang Wang, Yujia Li, Zhihao Lian, Shouxing Wei, Kashmala Jabbar, Muhammad Wisal, Ikramullah Khan, Muhammad Khalid, Jingyang Li

“…As molecular and genetic controls underlying CP development and formation of the MGU are unknown, it was hypothesized that physical association between germ cells and the VC nucleus might be lost in germ unit malformed (gum) mutants or in those which either block generative cell (GC) division or that additionally prevent gamete differentiation. …”
