Effect of successive enucleations of bovine corpora lutea on formation and function of subsequent luteal tissue.
I T has been demonstrated that exogenous progesterone exerts a stimulatory effect on ovulation in cattle (Hansel and Trimberger, 1952) as well as an inhibitory effect (Ulberg, Christian and Casida, 1951; Trimberger and Hansel, 1955; Nellor and Cole, 1957; Labhsetwar et al., 1964). However, the role of endogenous luteal progesterone in the regulation of bovine corpus luteum formation and functio...
متن کاملLevel set segmentation of bovine corpora lutea in ex situ ovarian ultrasound images
BACKGROUND The objective of this study was to investigate the viability of level set image segmentation methods for the detection of corpora lutea (corpus luteum, CL) boundaries in ultrasonographic ovarian images. It was hypothesized that bovine CL boundaries could be located within 1-2 mm by a level set image segmentation methodology. METHODS Level set methods embed a 2D contour in a 3D surf...
متن کاملExpression of fibroblast growth factor 13 (Fgf13) mRNA in bovine antral follicles and corpora lutea
Recent studies have suggested a paracrine role for several fibroblast growth factors (FGFs) in the regulation of follicle and luteal development. Fgf13 is a non-secreted FGF that has been previously localized to the developing gonads, but it is not known if it is expressed in the adult ovary. The objective of the present study was to determine the expression pattern of Fgf13 mRNA in the bovine ...
متن کاملMolecular characterization and expression of DERL1 in bovine ovarian follicles and corpora lutea
The endoplasmic reticulum (ER) is a major site of protein synthesis and facilitates the folding and assembly of newly synthesized proteins. Misfolded proteins are retrotranslocated across the ER membrane and destroyed at the proteasome. DERL1 is an important protein involved in the retrotranslocation and degradation of a subset of misfolded proteins from the ER. We characterized a 2617 bp cDNA ...
متن کاملComparison of induced corpora lutea from prepuberal gilts and spontaneous corpora lutea from mature gilts: in vitro progesterone production.
Prepuberal (P) gilts were induced to ovulate with pregnant mare serum gonadotropin followed 72 h later by human chorionic gonadotropin (hCG). Three P gilts and three mature (M) gilts each were ovariectomized on d 10, 14, 18, 22 and 26 (d 0 = day of hCG for P gilts and onset of estrus for M gilts). Gilts ovariectomized on d 14, 18, 22 and 26 were hysterectomized on d 6 to ensure maintenance of t...
