Summary
Ovarian function relies on blood vessel growth (angiogenesis), crucial for follicle and corpus luteum development. Understanding factors like FGF2 and VEGFA can improve treatments for infertility.
Area of Science:
- Reproductive biology
- Vascular biology
- Endocrinology
Background:
- Ovarian function depends on a dynamic vascular system for nutrient and hormonal support.
- Angiogenesis is critical for follicular growth, ovulation, and corpus luteum development.
- Vascular Endothelial Growth Factor A (VEGFA) is essential throughout ovarian development.
Purpose of the Study:
- To investigate the dynamic interplay between Fibroblast Growth Factor 2 (FGF2) and VEGFA in regulating luteal angiogenesis.
- To explore the role of pericytes and their interactions with endothelial cells in ovarian angiogenesis.
- To develop novel strategies for alleviating luteal inadequacy and infertility through targeted angiogenesis promotion.
Main Methods:
- Development of a novel ovarian physiological angiogenesis culture system.
- Analysis of dynamic expression patterns of angiogenic factors like FGF2 and VEGFA.
- Investigation of pericyte-endothelial cell interactions in vitro.
Main Results:
- FGF2 expression is dynamically upregulated during the follicular-luteal transition in cows, suggesting a key role in luteal angiogenesis.
- The novel culture system successfully formed organized endothelial cell networks, facilitating study of angiogenic factor interactions.
- Evidence suggests pericytes actively drive angiogenesis, highlighting the importance of pericyte-endothelial interactions.
Conclusions:
- Targeted promotion of angiogenesis, particularly understanding FGF2 and VEGFA roles, holds potential for treating ovarian dysfunction and infertility.
- The developed culture system provides a valuable tool for elucidating complex angiogenic regulatory mechanisms in the ovary.
- Further research into pericyte involvement may uncover new therapeutic targets for reproductive health.

01:24Regulation of Angiogenesis and Blood Supply
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...
01:10Mechanism of Angiogenesis
Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...
02:07Oogenesis
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...
01:26Ovaries
The ovaries are roughly the size of almonds and measure approximately 2 to 3 centimeters in length. These paired structures are situated within the pelvic region and are anchored by the mesovarium—a peritoneal extension that also connects them to the wider structure of the broad ligament. The support system extends to the suspensory ligament, housing blood and lymphatic vessels. In addition, the ovarian ligament tethers the ovaries to the uterus.

01:07Development of Blood Vessels
The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...

01:30Hormonal Control of the Ovarian Cycle
The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
