What is the difference between spermatogonia and primary spermatocytes? Each spermatogonia is diploid containing 46 chromosomes. Some spermatogonia undergo changes as they grow and increase in size by accumulating and assimilating the nourishing materials and are called primary spermatocytes which periodically undergo meiosis and others that are left behind are termed as spermatogonia. Difference Between Spermatogenesis and Oogenesis Overview. Spermatogenesis and oogenesis are the processes by which male and female gametes are formed. Spermatogenesis is the process by which sperms are formed, whereas oogenesis is the process by which ova are formed. Mitosis is then carried out on these type B spermatogonia in order to To study the transcriptional difference of spermatogonia between WT and SCARKO, we detected 22 upregulated genes and 80 down-regulated genes in SCARKO spermatogonia . GO term and KEGG pathway analysis revealed that downregulated DEGs were significantly related with those that function in spermatogenesis, reproductive process, male gamete However, a large proportion of the TEX genes appear to be vertebrate-specific - confirming the differences in spermatogenesis between vertebrates and invertebrates . germ cells (from spermatogonia to spermatids), Sertoli cells, and Leydig cells. This is true not only in humans but also in all mammals such as the mouse and the rat. In the Following is the process involved in spermatogenesis: 1. Mitosis and Meiosis: Mitosis: The process of cell duplication is known as mitosis. Two daughter cells are formed with accurately the similar DNA and chromosomal content of the original diploid (2N) mother cell. Human cells comprise of 46 chromosomes. In mammals, spermatogenesis is maintained throughout life by a small subpopulation of type A spermatogonia called spermatogonial stem cells (SSCs). In rodents, SSCs, or Asingle spermatogonia, form the self-renewing population. SSCs can also divide into Apaired (Apr) spermatogonia that are predestined to differentiate. Spermatogenesis and folliculogenesis involve cell-cell interactions and gene expression orchestrated by luteinizing hormone (LH) and follicle-stimulating hormone (FSH). FSH regulates the proliferation and maturation of germ cells independently and in combination with LH. In humans, the requirement for high intratesticular testosterone (T) concentration in spermatogenesis remains both a dogma Johnson and Neaves revealed age-related differences between 2- and 20-year-old stallions in the Leydig cell population. For normal and efficient regulation of spermatogenesis, dead spermatogonia and residual bodies are degraded and phagocytosed by Sertoli cells through a phospholipid phosphatidylserine (PS)-dependent pathway .
