Stem Cell Markers

Yet more confirmations of the potency of our Stem Cell Markers.

In this study the authors demonstrate a between SSCs and RET.

ETV5 is expressed beginning in fetal Sertoli cells and can potentially have effects on both neonatal Sertoli and germ cells. In addition, ETV5 has critical effects on neonatal spermatogonial proliferation, which may involve impaired signaling through the RET receptor.

Images: Ret IHC in WT and Etv5-/- testes (n=4). The intensity of RET staining per spermatogonia is markedly reduced in Etv5-/- testis (B) even though the number of cells staining for RET are comparable to the WT (A) testis. Insets are higher magnification of spermatogonia showing differences in staining intensity. Bars = 50 μm in A and B, insets = 10 μm.
