In order to investigate the function of gonadal somatic cells in the sex differentiation of germ cells, we produced chimera fish containing both male (XY) and female (XX) cells by means of cell transplantation between blastula embryos in the medaka, Oryzias latipes. Sexually mature chimera fish ...
Sensitive system for visualising biotinylated DNA probes hybridised in situ: rapid sex determination of intact cells A fast and sensitive method for detecting biotinylated deoxyribonucleic acid (DNA) probes was used for sex determination of cells and tissues by in situ hy......
This suggests that SMAD4 and STRA8 are essential intrinsic factors that determine the female fate of germ cells, collaborating to suppress expression of male genes. Mammalian sex depends on a male-specific gene, sex-determining region Y (SRY), which is located on the Y chromosome. Individuals ...
We describe here a novel reporter mouse line that expresses enhanced green fluorescent protein under the control of an Sf1 promoter fragment, marking Sertoli and granulosa cell precursors during the critical period of sex determination. These cells were purified from gonads of male and female ...
In Drosophila , mutations at the transformer-2 , the double-sex , or the intersex loci interfere with the normal sexual development of somatic cells. In order to study the effect of mutations at these loci on germ cell development, mutant germ cells were introduced into normal female or norma...
The median incidence of sex chromosome aneuploidy in the oligozoospermic group was 4.5% (range, 0.8-7.3%), while in the control group it was 0.7% (range, 0.2-1.2%)., CONCLUSION: The incidence of aneuploidy in somatic cells is significantly greater in oligozoospermic men than in normal ...
However, XX germ cells that develop in masculinized animals also express mgm1. Therefore, somatic sex-determining signals have already acted on XX germ cells in 10-hour-old embryos. 展开 关键词: germline mgm1 sex determination sex-specific marker Drosophila ...
Sex-Specific Apoptosis Regulates Sexual Dimorphism in the Drosophila Embryonic Gonad Sexually dimorphic development of the gonad is essential for germ cell development and sexual reproduction. We have found that the Drosophila embryonic gonad is already sexually dimorphic at the time of initial gonad ...
Influence of sex steroids on the production of prostaglandins F2 alpha and E2 and response to oxytocin in cultured epithelial and stromal cells of the bovi... The uterus is a primary target for sex steroid action in vivo during the estrous cycle and pregnancy. Cell cultures have been used to...
