Microinsemination with first-wave round spermatids from immature male mice.
In several mammalian species, including mice, round spermatids have been used to produce normal offspring by means of microinsemination techniques. In this study, we examined whether mouse round spermatids retrieved from immature testes undergoing the first wave of spermatogenesis had acquired fertilizing ability comparable to cells from mature adults. Microinsemination with round spermatids wa...
متن کاملGeneration of histocompatible androgenetic embryonic stem cells using spermatogenic cells.
Androgenetic embryonic stem (aES) cells, produced by pronuclear transplantation, offer an important autologous pluripotent stem cell source. However, the isolation of aES cells, particularly individual-specific aES cells, with the use of fertilized embryos has limited the practical applications of this technology in humans. In this study, we applied a new approach, essentially described as soma...
متن کاملImmature sound localisation and abnormal development.
This investigation tested the hypothesis that high risk infants showing immaturity in localisation of a sound stimulus would be more likely to have appreciable neurodevelopmental dysfunction. The cohort comprised 112 infants, 66 of whom were classified as 'high risk'. Every infant underwent a neurological and developmental assessment, a sound localisation response test, and an audiological exam...
متن کاملMurine cytomegalovirus infects spermatogenic cells.
Murine cytomegalovirus replicated in reproductive tissue of male mice infected with the virus. We examined three strains of mice latently infected by injection at birth with 100 plaque-forming units of the virus. As adults, these mice contained within their testes 4--6 viral genomic equivalents per 100 cells, as tested by hybridization between mouse DNA and cytomegalovirus DNA. Acutely infected...
متن کاملO-6: Maturation of Spermatogenic Cells in Artificial Seminiferous Tubules
Background This study aimed to investigate whether Artificial Seminiferous Tubules (AST) coated with testicular extra cellular matrix (ECM) support maturation of spermatogenic cells from immature testes. MaterialsAndMethods Medical grade tubes coated with testicular ECM were used. Testes from immature mice were loaded in the concentration of 10000- 20000/ml. Tubes were then immersed in germ cel...
