Recent developments in testis tissue xenografting.
Development of the mammalian testis and spermatogenesis involve complex processes of cell migration, proliferation, differentiation, and cell-cell interactions. Although our knowledge of these processes has increased in the last few decades, many aspects still remain unclear. The lack of suitable systems that allow to recapitulate and manipulate both testis development and spermatogenesis ex si...
متن کاملXenografting of adult mammalian testis tissue.
Xenografting of testis tissue from immature males from several mammalian species to immunodeficient mouse hosts results in production of fertilization-competent sperm. However, the efficiency of testis tissue xenografting from adult donors has not been critically evaluated. Testis tissue xenografting from sexually mature animals could provide an option to preserve the genetic material from valu...
متن کاملTissue, cell type and stage-specific ectopic gene expression and RNAi induction in the Drosophila testis
The Drosophila testis has numerous advantages for the study of basic cellular processes, as production of sperm requires a highly orchestrated and complex combination of morphological changes and developmentally regulated transitions. Experimental genetics using Drosophila melanogaster has advanced dramatically with the advent of systems for ectopic expression of genetic elements in specific ce...
متن کاملXenografting of human fetal testis tissue: a new approach to study fetal testis development and germ cell differentiation
BACKGROUND Abnormal fetal testis development can result in disorders of sex development (DSDs) and predispose to later testicular dysgenesis syndrome (TDS) disorders such as testicular germ cell tumours. Studies of human fetal testis development are hampered by the lack of appropriate model, and intervention systems. We hypothesized that human fetal testis xenografts can recapitulate normal dev...
متن کاملP-209: Decreased Expression of Histone Acetyltransferase CDY1 Gene in Testis Tissue May Lead to Decreased Expression of Transition Protein (TNP) and Protamine (PRM) Genes,Causing Male Infertility
Background: Infertility is a complex medical problem. About 15% of couples are infertile, and male infertility being involved in roughly 50% of the cases. Among these, many cases are associated with a severe impairment of spermatogenesis. During the last stage of spermatogenesis (spermiogenesis), sperm chromatin endures complex modifications in which histones are lost and depositioned with tran...
