the complex process of spermatogenesis is regulated by various factors. studies on spermatogonial stem cells (sccs) have provided very important tool to improve herd genetic and different field. 0.2 to 0.3 percent of total cells of seminiferous tubules is consist of spermatogonial stem cells. to investigate and biomanipulation of these cells, proliferation and viability rate of cells should be ...

The continuous production of mammalian sperm is maintained by the proliferation and differentiation of spermatogonial stem cells, which originate from primordial germ cells in the early embryo. Previously, we reported that the transplantation of fetal male gonadal tissue into the recipient testis was effective obtaining functional sperm. This transplantation technique is a promising new approac...

Background Male infertility management has made significant progress during the past three decades, especially after the introduction of intracytoplasmic sperm injection (ICSI) in 1992. However, many boys and men still suffer from primary testicular failure due to acquired or genetic causes. New and novel treatments are needed to address these issues. Spermatogenesis originates from spermatogon...

Adult stem cells show excellent perspectives for applications in the field of regenerative medicine. In the last two decades, great strides have been made in spermatogonial stem cell research showing the potentiality of these stem cells in organ regeneration. Spermatogonial stem cells, derived from post-natal or adult mice, not only differentiate into cell types other than the spermatozoa when ...
