Progesterona e hormônio folículo-estimulante interagem e promovem a sobrevivência e o desenvolvimento in vitro de folículos pré-antrais caprinos [PDF]

, 2012
Este trabalho veri_icou os efeitos da progesterona e do hormonio foliculo-estimulante (FSH) na sobrevivencia e no crescimento de foliculos pre-antrais caprinos. Fragmentos de tecido ovariano foram cultivados por 1 ou 7 dias em Meio Essencial Minimo (MEM)

Cryopreservation of swine ovarian tissue : effect of different cryoprotectants on the structural preservation of preantral follicle oocytes [PDF]

, 2009
The present study aimed to test different cryoprotectants on cryopreservation of pig ovarian tissue. Pig ovaries (n = 3) were collected at a local slaughterhouse. From each ovary, ten cortex samples were taken.

Development of antral follicles after xenografting of isolated small human preantral follicles

Reproductive BioMedicine Online, 2008
Small human pre-antral follicles can be enzymatically isolated from the surrounding stroma, and are able to survive after 7 days of xenografting. The aim of the present study was to assess the developmental capacity of enzymatically isolated human follicles after long-term xenografting to severe combined immunodeficient (SCID) mice.

Canine preantral follicles cultured with various concentrations of follicle-stimulating hormone (FSH)

Theriogenology, 2010
The objective was to evaluate the effects of various concentrations of exogenous FSH during in vitro culture of isolated canine preantral follicles. Preantral secondary follicles (>200 microm) were isolated by microdissection and cultured for 18 d in supplemented alpha-Minimum Essential Medium (alpha-MEM).

Effects of lowered temperatures and media on short-term preservation of zebu (Bos indicus) preantral ovarian follicles [PDF]

, 2004
The maintenance of follicle quality during the transportation of ovaries is essential for the successful cryopreservation and in vitro development of preantral follicles. The objective of this study was to evaluate the effect of cooling ovarian tissue on

Ultrastructural features of agouti (Dasyprocta aguti) preantral follicles cryopreserved using dimethyl sulfoxide, ethylene glycol and propanediol [PDF]

, 2012
The objective was to develop an efficient protocol for cryopreservation of agouti (Dasyprocta aguti) ovarian tissue. Agouti ovarian fragments were placed, for 10 min, in a solution containing MEM and fetal bovine serum plus 1.5 M dimethyl sulfoxide (DMSO)

FOLLICLE POPULATIONS IN MARE OVARIES: FROM PREANTRAL TO PREOVULATORY FOLLICLES

Enciclopédia Biosfera, 2015
The purpose of this study was to describe morphological and quantitative aspects of preantral and antral follicles in the equine ovary. Six ovaries were collected from necropsied mares and sliced lengthwise parallel to the ovulation fossa. The slices were fixed and processed for histological evaluation under light microscopy.

Comparative Single‐Cell Transcriptomic Atlas Reveals the Genetic Regulation of Reproductive Traits

Advanced Science, EarlyView.
A cross‐species single‐cell transcriptomic atlas of reproductive and central nervous system tissues from sheep and humans reveals conserved cellular programs and regulatory networks that regulated fertility. Integration with GWAS for sheep lifetime average litter size identifies UNC5–SLIT–BMP signaling as a core pathway coordinating neuroendocrine ...
