The studies conducted to determine the stage of its usability in prospective fertility restoration testicular tissues taken from prepubertal patients undergoing oncology treatment were screened. In addition, current status spermatogonial stem cell cultures, tissue and organoid research their potential examined.
 Spermatogonial cells are only found tissue. Germinal serial not found. Since s...

Spermatogonial stem cells (SSCs) maintain spermatogenesis throughout the reproductive life of mammals. While A(single) spermatogonia comprise the rodent SSC pool, the identity of the stem cell pool in the primate spermatogenic lineage is not well established. The prevailing model is that primate spermatogenesis arises from A(dark) and A(pale) spermatogonia, which are considered to represent res...

The past 30 years have been marked by unparalleled accomplishments in the medical treatment of malignancy. Prior to advances in chemotherapeutic and radiation treatment, many oncologic conditions had dismal survival rates. Today, medical interventions have success rates that approach complete remission for many malignancies. An inadvertent complication of these therapies, however, has been the ...

The existence of spermatogonial stem cells in the testis offers clinically relevant options for preservation and restoration of male fertility. New approaches based on male germ cell transplantation and testicular tissue grafting can be applied to generate a limited number of sperm cells and could therefore be considered important new avenues for restoration of fertility in oncological patients...

The formation of mature spermatozoa is one of the most essential functions in life. A concerted sequence of events is needed to proliferate, maintain and mature germ cells starting with spermatogonial stem cells and culminating in mature gametes. Apart from the genetic background, this process requires highly organized tissue in which the complex process of spermatogenesis is strongly regulated...

OBJECTIVE To develop an efficient infusion technique for human spermatogonial stem cell transplantation. DESIGN A mixture with ultrasonic contrast, computerized tomography (CT) contrast, and Chinese ink was injected into isolated human testes through different sites (the rete testis, the head of the epididymis, the deferent duct, and blind testicular infusion). Ultrasound transducer was used ...

The mature mammalian testis is a marvelous organ that produces numerous sperm cells during its reproductive phase. This biologically significant process consists of three steps: stem cell self-renewal and differentiation, meiosis and genetic recombination, and haploid cell morphogenesis into sperm (Russell et al., 1990). The first step provides a good model for investigating the molecular mecha...

Stem cells are unique that have the ability to differentiate into with specific functions and renew themselves produce new stem cells. One type of actively studied is Spermatogonial Cells (SSC). SSC a unipotent cell develops spermatozoa in mammalian testis. can be transplanted male testis recipients improve genetic quality livestock propagate valuable livestock. transplantation procedure starte...
