Co-transplantation of mesenchymal stem cells improves spermatogonial stem cell transplantation efficiency in mice

Stem Cell Research & Therapy, 2018
Background Spermatogonial stem cell transplantation (SSCT) could become a fertility restoration tool for childhood cancer survivors. However, since in mice, the colonization efficiency of transplanted spermatogonial stem cells (SSCs) is only 12%, the ...

Comparative Transcriptome Analysis of Differentially Expressed Genes and Signaling Pathways between XY and YY Testis in Yellow Catfish. [PDF]

PLoS ONE, 2015
YY super-males have rarely been detected in nature and only been artificially created in some fish species including tilapia and yellow catfish (Pelteobagrusfulvidraco), which provides a promising model for testis development and spermatogenesis.

Spermatogonial stem cells as a source for regenerative medicine

Middle East Fertility Society Journal, 2012
Several researchers have reported the derivation of multipotent cells from both mouse and human spermatogonial stem cells. These spermatogonia-derived stem cells show similarities with embryonic stem cells both for phenotype and functionality, indicating

Y/X-Chromosome-Bearing Sperm Shows Elevated Ratio in the Left but Not the Right Testes in Healthy Mice

Life, 2021
The sex chromosomes play central roles in determining the sex of almost all of the multicellular organisms. It is well known that meiosis in mammalian spermatogenesis produces ~50% Y- and ~50% X-chromosome-bearing sperm, a 1:1 ratio. Here we first reveal

Setting Up a Cryopreservation Programme for Immature Testicular Tissue: Lessons Learned After More Than 15 Years of Experience

Clinical Medicine Insights: Reproductive Health, 2019
Young boys undergoing gonadotoxic treatments are at high risk of spermatogonial stem cell (SSC) loss and fertility problems later in life. Stem cell loss can also occur in specific genetic conditions, eg, Klinefelter syndrome (KS).

Abdominal wall ectopic testis - Case report and review of literature

Journal of Pediatric Surgery Case Reports, 2018
Undescended testis is a common condition which affects about 2–4% of male infants and more commonly seen in preterm infants. The descent of testis is a complex process which requires cross talk between various hormones and testes.
