In an example where female tissue was transplanted into a male host, donor cells contributing to the developing testis retained a female identity and expressed a marker of female function. Our study demonstrates that avian somatic cells possess an inherent sex identity and that, in birds, sexual ...
In Drosophila, the enhancer-trap line mgm1 is already specifically expressed in male germ cells. Staining is first detected in 10-hour-old embryos and it is found in later stem cells. This line, which reveals the earliest sex-specific gene expression in the germline known so far, is a use...
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 ...
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 ...
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......
The two X chromosomes in the female cells were similar in size and morphology but differed in the DNA replication pattern. Studies of the meiotic chromosomes in the male germ-line cells revealed 23 autosome bivalents and the sex chromosomes either as an XY bivalent or X and Y univalents. ...
Role of Kidneys in Sex Differences in Angiotensin II–Induced HypertensionNovelty and Significance The significance of kidneys in regulation of sodium and water balance and hemodynamics has been demonstrated both in patients and animal models. In the pre......
(s): Cytogenetic analysis of somatic cells and determination by fluorescence in situ hybridization of aneuploidy frequencies for the gonosomes (sex chromosomes) and chromosome 18 in sperm from whole and Percoll-separated semen.Main Outcome Measure(s): Somatic and gametic aneuploidy were scored....
The origin of EFNB1 mutations in craniofrontonasal syndrome: frequent somatic mosaicism and explanation of the paucity of carrier males. Craniofrontonasal syndrome (CFNS) is an X-linked disorder that exhibits a paradoxical sex reversal in phenotypic severity: females characteristically have ... SRF ...
Each set consisted of compatible and common-AB diploids otherwise almost isogenic. One of the sets included two compatible diploids with a large proportion of dikaryotic cells. The sectors were isolated and analysed for evidence of aneuploidy and frequent crossing over to determine whether they ...
