Central to the growth and development of the corpus luteum, therefore, is luteal vascular growth, which appears to be regulated primarily by the angiogenic growth factors, basic fibroblast growth factor and vascular endothelial growth factor. In addition, the corpus luteum is a complex tissue ...
Summary 1. Published descriptions of the development of the corpus luteum show that the majority of the luteal cells are derived from the granulosa cells. 2. In the vertebrates, other than mammals, the development of a corpus luteum does not appear to be associated solely with viviparity. 3....
The influence of episodic LH pulses before and subsequent to ovulation on size and function of the corpus luteum (CL) in cattle was examined. Treatments were 1) control; 2) LHRH antagonist starting 2 days before the preovulatory LH surge (Antagonist [Ant] -2); 3) LHRH antagonist at initia...
The apoptosis of granulosa cells is involved in follicular atresia and degeneration of the corpus luteum. The mechanisms that regulate follicular atresia a... K Yukiyo,K Kazuhiro,S Toshiharu,... - 《Molecular Human Reproduction》 被引量: 51发表: 2005年 内分泌因子、生长因子、细胞因子与卵巢卵泡的...
Observations were made on the number of primary, secondary, and tertiary oocytes, and also De Graaf follicles and corpus luteum. Data were statistically analyzed using One Way ANOVA method. The results showed there were no significantly differences (P>0.05) on the number of primary, secondary, ...
DEVELOPMENT OF FEMALE RATS INJECTED SHORTLY AFTER BIRTH WITH TESTOSTERONE OR >>ANABOLIC STEROIDS<< The present work is concerned with early effects of a single injection of 1.5 mg testosterone propionate into 5 day old female rats (injected rats). Effects of anabolic steroids given to rats shortly...
Under the primary influence ofestrogensfrom the maturing ovary atpuberty, the ductal cells proliferate and form branches. Afterovulation,progesteronefrom thecorpus luteum, anorganthat develops in the ovary each time an ovum has been shed and has the function of preparing the uterus for receiving the...
The corpus luteum is a temporary ovarian structure; it is defined as the remnants of a mature follicle that has released an egg, and its function is dependent on whether the egg is subsequently fertilized. Interestingly, Tie1 knockdown in ovaries significantly decreased the weights of ovaries and...
Specimens were obtained from the uteri of heifers on Days 17, 18, 20 to 30 and at 3-day intervals up to Day 45 of gestation and this material was examined by light microscopy, transmission and scanning electron microscopy. A reduction in height of the uterine epithelium on Day 18 was the...
