Project description:Spermatogonial stem cells (SSCs) cotinues to produce sperm throughout life by self-renewal division. Although it is possible to expand SSCs from most of the mouse strains in vitro for a long-term period by supplementing GDNF and FGF2, SSCs from a 129 background do not proliferate under the same culture conditions. Since it suggested that they have distinct self-renewal requirements, gene expressions of spermatogonia enriched from testes of DBA/2, C57BL/6, and 129 strains were compared. In this dataset, we include the expression data obtained from spermatogonia enriched from 12dpc testes of DBA/2, C57BL/6, and 129. Enrichment was performed by magnetic activated-cell sorting using anti-Ecadherin (CDH1) antibody (ECCD2). These data are used to obtain 359 genes that are differentially expressed among DBA/2, C57BL/6, and 129.
Project description:We sequenced mRNA in grossly enlarged testes from 1-year-old Stra8-deficient mice, and in testes from adult male wild-type controls, to verify that Stra8-deficient testes are enriched for genes normally expressed in type A spermatogonia.

Examination of mRNA levels in 6 whole-testis samples (3 replicates of each genotype). Specifically, we sequenced mRNA in grossly enlarged testes from three 1-year-old Stra8-deficient male mice, and in normal testes from three adult male wild-type controls
Project description:In adult mouse testis, undifferentiated spermatogonia include GFRα1+ and NGN3+ populations. The former mainly act as self-renewing stem cells that support steady-state spermatogenesis. Whilst, the latter are primed for differentiation, but retain the potential of self-renewal and contribute to regeneration and post-transplantation colony formation (Nakagawa et al. science .2010; Hara et al. cell stem cell. 2014). And, NGN3+ cells can differentiate to KIT+ cells, which are also mentioned differentiated spermatogonia, by retinoic acid signal. The gene expression profiles of GFRα1+, NGN3+ and KIT+ spermatogonia, as well as the whole testis samples, were investigated here by microarray (Ikami et al. development. 2015).
