Abstract

Spermatogonial stem cells (SSCs), which are at the basis of spermatogenesis process, are valuable cells with different applications in biotechnology and regenerative medicine. Understanding the molecular basis of SSC self-renewal and differentiation at various developmental stages of the male organism is crucial to find key factors in the SSCs fate and function. Therefore, this study was aimed to use single-cell RNA-sequencing dataset analysis for identification of differentially expressed genes (DEGs) and their regulators in 3 and 7 days old mouse-derived single SSCs (mSSCs). Results showed 68 upregulated and 203 downregulated genes in 7 days old mouse-derived SSCs compared to 3 days old mSSCs, which were associated with 1493 and 3077 biological processes, respectively. It also found that DAZL, FKBP6, PAIP2, DDX4, H3F3B, TEX15, XRN2, MAEL, and SOD1 are important factors with the higher gene expression pattern, which may be pivotal for mSSCs fate and function during development of germ cells. Moreover, NR3C1, RXRA, NCOA, ESR1, PML, ATF2, BMI1, POU5F1, and CHD1 were the main central regulators for the upregulated DEGs, while HNF1A, C/EBPα, and NFATC1 were the master regulators for the downregulated DEGs. In this regard, two sign...Continue Reading

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
