Heterogeneous cell types in the corpus luteum of sheep, goats and cattle.
Data on the structure, quantitation, origins and functions of the large luteal (LL) and small luteal (SL) cells of sheep, goats and cattle are reviewed. Both LL and SL cells show ultrastructural features consistent with a steroidogenic function. However,

The effect of exogenous glucose infusion on early embryonic development in lactating dairy cows [PDF]
peer-reviewedThe objective of this study was to examine the effect of intravenous infusion of glucose on early embryonic development in lactating dairy cows. Nonpregnant, lactating dairy cows (n = 12) were enrolled in the study (276 ± 17 d in milk). On d

Differential actions of second messenger systems in the corpus luteum.
Our current working hypothesis for the intracellular mechanism of action for LH and PGF-2 alpha is shown in Fig. 8. Luteinizing hormone appears to act primarily on the small luteal cell through the cAMP/protein kinase A effector system and thereby ...

Comparison of synchronized-ovulation protocols and traditional synchronized-estrys programs using prostaglandin F2(alpha) [PDF]
Five treatments were developed to compare a new synchronized ovulation protocol, which programs follicular development with the regression of the corpus luteum, and traditional prostaglandin protocols that only control the regression of the corpus ...

Structural and functional properties of the corpus luteum of pregnancy.
In domestic ruminants the parenchyma of the corpus luteum consists of two subpopulations of steroidogenic cells commonly referred to as small and large luteal cells.

Morphological Aspects in Corpus Luteum Formation in Mice
Immediately after ovulation, in the follicular cavity, by multiplying and metaplasia of granulosa and internal sheath cells, a transient endocrine gland is formed, known as the corpus luteum (corpus luteum). Although in adult mice, ovulation occurs every

Biosynthesis of retinal in bovine corpus luteum
Bovine corpus luteum tissue was sliced and incubated with β-[15,15′-3H]carotene. The conversion of radioactive β-carotene into radioactive retinal was substantiated utilizing column chromatography, thin-layer chromatography, high-speed liquid ...

Review: Comparative of monitoring estrus cycle in livestock: Hormonal features and ultrasound
The estrus cycle is a period in which a female animal shows the ability to become pregnant, and this event will continue over some time. The estrus cycle has two different phases, the follicular phase characterized by the presence of graffian follicles ...
