Unique Epigenetic Programming Distinguishes Regenerative Spermatogonial Stem Cells in the Developing Mouse Testis (ChIP-seq)

Project description:Background: Spermatogonial stem cells (SSCs) sustain the process of steady-state spermatogenesis in the mammalian testis, which is critical to the ongoing production of sperm and male fertility. SSCs can both self-renew to perpetuate the SSC population, and give rise to progenitors to propel the spermatogenic differentiation pathway. SSCs are detectable as a small subpopulation of undifferentiated spermatogonia that demonstrate regenerative capacity in a transplantation assay, and can be selectively recovered on the basis of expression of an Id4-eGfp sortable marker transgene. Enriched populations of SSCs and progenitors display consistent differences in gene expression patterns suggesting they represent discrete spermatogonial subtypes. Results: Here we describe distinct spermatogonial subtype-specific epigenetic programming profiles associated with subtype-specific differential gene expression on the basis of genome-wide patterns of six different histone modifications, chromatin accessibility, and DNA methylation. We find that similarly expressed genes show no differences in epigenetic programming, whereas differentially expressed genes show distinct histone modification patterns as well as subtype-specific differences in patterns of distal intergenic low-methylated regions. Motif-enrichment analysis of differentially programmed elements predicts a set of transcription factors that may regulate this spermatogonial subtype-specific epigenetic programming, and gene-specific chromatin immunoprecipitation analyses confirm subtype-specific differences in binding of a subset of these factors to target genes. Conclusions: Taken together, these results indicate that SSCs and progenitors are discrete spermatogonial subtypes that appear to be differentially programmed to carry out mutually exclusive functions including self-renewal and maintenance of regenerative capacity in SSCs and lineage commitment and loss of regenerative capacity in progenitors.

Unique Epigenetic Programming Distinguishes Regenerative Spermatogonial Stem Cells in the Developing Mouse Testis.

Project description:Spermatogonial stem cells (SSCs) both self-renew and give rise to progenitors that initiate spermatogenic differentiation in the mammalian testis. Questions remain regarding the extent to which the SSC and progenitor states are functionally distinct. Here we provide the first multiparametric integrative analysis of mammalian germ cell epigenomes comparable with that done for >100 somatic cell types by the ENCODE Project. Differentially expressed genes distinguishing SSC- and progenitor-enriched spermatogonia showed distinct histone modification patterns, particularly for H3K27ac and H3K27me3. Motif analysis predicted transcription factors that may regulate spermatogonial subtype-specific fate, and immunohistochemistry and gene-specific chromatin immunoprecipitation analyses confirmed subtype-specific differences in target gene binding of a subset of these factors. Taken together, these results show that SSCs and progenitors display distinct epigenetic profiling consistent with these spermatogonial subtypes being differentially programmed to either self-renew and maintain regenerative capacity as SSCs or lose regenerative capacity and initiate lineage commitment as progenitors.
