() Chromatin and transcription transitions chromatin and transcription transitions of mammalian adult germline stem cells and spermatogenesis of mammalian adult germline stem cells and spermatogenesis. Along with many of the genome-wide transitions in chromatin composition throughout. To better understand how chromatin regulates AGSC biology and gametogenesis, we derived stage-specific high-resolution profiles of DNA methylation, 5hmC, histone modifications/variants, and RNA-seq in AGSCs and during spermatogenesis. The maintenance and regulation of SSC function are strictly dependent on a supportive niche that is composed of multiple cell types. Note that GS cells showed the expressions of Meiosin and Stra8 in response to RA, whereas ES cells showed the expression of Stra8 but not Meiosin. Enter the password to open this PDF file: Cancel OK.

Chromatin and Transcription Transitions of Mammalian Adult Germline Stem Cells and Spermatogenesis. Jenkins TG, Aston KI, Pflueger C, Cairns BR, Carrell DT ().

During spermatogenesis, germ cells undergo massive cellular reconstruction and dynamic chromatin remodeling to facilitate highly diverse transcriptomes, which are required for the production of functional sperm. Here, we use the Drosophila GSC lineage to systematically analyze the transcriptome of discrete but continuously differentiating germline cysts. To better understand AGSCs chromatin and transcription transitions of mammalian adult germline stem cells and spermatogenesis and gametogenesis, we derived high-resolution profiles chromatin and transcription transitions of mammalian adult germline stem cells and spermatogenesis of transcription, DNA methylation, 5hmC, and multiple histone. Human adult spermatogonial stem cells (hSSCs) must balance self-renewal and differentiation.

Transcription and imprinting dynamics in developing postnatal male germline stem cells. However, it remains unknown how germline chromatin is organized to promote the dynamic, complex transcriptomes of spermatogenesis. These differentiate synchronously to spermatocytes (SpC) that replicate their chromosomes and enter meiosis.

To understand how this is achieved, we profiled DNA methylation and open chromatin (ATAC-seq) in SSEA4 + hSSCs, analyzed bulk and single-cell RNA transcriptomes (RNA-seq) in SSEA4 + hSSCs and differentiating c-KIT + spermatogonia, and performed validation studies via immunofluorescence. E(Pc) acts in the cyst stem cell (CySC) lineage to negatively control the transcription of genes associated with multiple cell signaling pathways, including both the JAK-STAT and the EGF signaling.

Based chromatin and transcription transitions of mammalian adult germline stem cells and spermatogenesis on these findings, it is believed that bivalent domains maintain the development potential of these genes throughout the germline.

First, spermatogonial stem cells (SSCs) give rise to extensive numbers of undifferentiated spermatogonia cells. The fate and function of epigenetic marks during the germline-to-embryo transition is a key issue in developmental biology, with relevance to stem cell programming and trans-generational inheritance.
