Sex chromatin of trophoblastic tumors
American Journal of Obstetrics and Gynecology, 1966Abstract The incidence of sex chromatin was determined in 48 trophoblastic tumors. Of 30 cases of hydatidiform mole and chorioadenoma destruens, 29 (97 per cent) were sex chromatin positive or female. Fourteen (78 per cent) of 18 choriocarcinomas were also sex chromatin positive.

Testicular biopsies from 16 patients with Klinefelter's syndrome were examined for the presence of sex chromatin in Sertoli cells. The examination revealed a dimorphism which could be correlated with the presence of two morphologically different types of

A sex chromatin and Y body survey of Toronto newborns.
Canadian journal of genetics and cytology. Journal canadien de génétique et de cytologie, 1974Sex chromatin determinations were performed on the amniotic membranes of 72,739 newborns in 11 Toronto hospitals. These analyses, carried out between I October 1967 to 31 May 1971, identified 40 XXY subjects, 16 XXX, 1 XO, 1 XXYY as well as 9 mosaics of ...

Sex chromatin in avian species
Canadian Journal of Zoology, 1972A comparison of nuclear chromatin bodies in squash preparations of interphase cell nuclei of white Chinese geese (Cygnopsis cygnoid), domestic ducks (Anas platyrynchos var. domestica), and domestic chicken (Gallus domesticus) with those of ferret (Putorius furo) embryonic cells from skin, gastrointestinal muscularis, kidney, and spinal cord was made ...

Peripheral Position of Sex Chromatin
Nature, 1961IN examining buccal smears for sex chromatin, one finds a surprisingly high incidence of sex chromatin bodies not merely at the nuclear membrane but also more precisely at the periphery of what appears to be a disk-shaped nucleus. The following discussion will provide evidence that, as in tissue cultures1, the sex chromatin is characteristically at the

Nature, 1964 Sex Chromatin and Human Chromosomes
1962Publisher Summary This chapter reviews the work done on sex chromatin and human chromosomes in the past few years. Evidence reviewed suggests that sex chromatin is chromosomal in origin and is most likely formed from one X chromosome only. There is overwhelming support for the diploid number of human chromosomes being 46 and not 48.
