Project description:The maintenance of spermatogenesis in adult males is dependent on a population of mitotic germ cells with self-renewal potential known as undifferentiated spermatogonia. Regulation of undifferentiated spermatogonia function is dependent on transcriptional and post-transcriptional mechanisms. We have identified an essential role for the RNA helicase DDX5 in undifferentiated spermatogonia through generation of a UBC-CreERT2;Ddx5flox/flox mouse model that allows tamoxifen-dependent Ddx5 ablation. To identify genes regulated by DDX5, we generated lines of cultured undifferentiated spermatogonia from these mice and treated cells with tamoxifen (TMX) to induce Ddx5 knockout or vehicle (VEH) as a control, and performed RNA-sequencing analysis to compare these conditions.

Identification of gene targets of the transcription factor SALL4 in undifferentiated spermatogonia

Project description:Sustained spermatogenesis in adult males and recovery of fertility following germ cell depletion are dependent on undifferentiated spermatogonia with self-renewal potential. We have previously demonstrated a critical role for the transcription factor Spalt-like 4 (SALL4) in spermatogonial differentiation. However, it remains unclear whether SALL4 has broader roles within the spermatogonial pool despite its ability to co-regulate genes with PLZF, a transcription factor required for undifferentiated cell maintenance. To identify genes regulated by SALL4 in the male germline, we established cultures of undifferentiated spermatogonia from a Sall4 inducible knockout mouse model. Cells were treated with vehicle (as control) or tamoxifen to induce gene deletion, then cells harvested and analysed by microarray to identify genes mis-expressed upon loss of SALL4.
