In vitro culture of buffalo (Bubalus bubalis) preantral follicles

Theriogenology, 2002
Growth of buffalo preantral follicles in culture was studied to investigate the effect of size of preantral follicles, individual or group culture, long-term culture of preantral follicles for (40 days), addition of human follicle stimulating hormone (FSH), insulin-transferrin-selenium (ITS), growth factors (epidermal growth factor (EGF), fibroblast ...

Morphogenetic reaggregation and luteinization of mouse preantral follicle cells

American Journal of Anatomy, 1979
AbstractSmall (60‐90 μm) and large (100‐130 μm) preantral follicles were isolated from adult mouse ovaries by a collagenase‐dissection technique. These follicles were composed of resting oocytes surrounded either by granulosa cells, only, or by granulosa and undifferentiated theca cells.

In-vivo and in-vitro development of preantral follicles

Theriogenology, 1997
Abstract This paper presents the state of the art concerning the in vitro growth and differentiation of preantral follicles, i.e. from the primordial to the antral stage, in mammals. Attention is paid to their normal structure and development, nomenclature, isolation and culture methods, effects of systemic and local compounds on their development ...

Hormones and preantral follicle growth in women.

Mayo Clinic proceedings, 1976
Studies of follicular morphology in biopsies of human ovarian tissue obtained from women with a syndrome of hypogonadotropic hypogonadism have been reviewed. Follicular maturation was consistent with that seen in ovarian tissues removed at postmortem examination of infants.

[Development of human fetal preantral follicles in vitro].

Zhonghua fu chan ke za zhi, 2000
To study oocyte maturation of human fetal preantral follicles in vitro, the effects of different factors on oocyte maturation.Preantral follicles were obtained from fetal ovaries from termination of 20-28 weeks gestation. Factors involved in the development, maturation of fetal preantral follicles were studied in tissue and cell culture by means of ...
