Gunther J. Tichythe time we began our studies, it was known that peptide growth factors were potent mitogens for granulosa cells of the pig and other species (1,2). In addition, insulin at high concentrations was known to influence granulosa cell growth and differentiation (3), but effects of IGFs on ovarian cells混合 发表于 2025-3-23 22:49:37
Gunther J. Tichyvarian regulators. To further assess the role of these peptides in ovarian function, we have employed a neutralizing monoclonal antibody to IGF-I to block the actions of IGFs in porcine follicular fluid and in granulosa cell-conditioned medium. Granulosa cells from immature porcine follicles were cu钉牢 发表于 2025-3-24 06:05:10

Gunther J. Tichyty allows tumor cells to invade locally and into neighboring organs, penetrate blood vessels, and metastasize to distant organs. Metastasizing tumor cells show increased migratory capacity and altered matrix degradation and deposition. A partial loss of epithelial cell fate differentiation and a gai强制令 发表于 2025-3-24 13:39:11

Gunther J. Tichyine epithelial cells must double within two days and return to normal levels in the next two. This process is repeated throughout the reproductive lifetime of the animal, which means that the murine uterine epithelium will be reconstituted approximately 90 times in one year.

The ovaries (under pituitary control) promote glandular growth and differentiation, while the pituitary itself directly controls lactation. Proliferation of normal mammary epithelium seems to require both estrogen and progesterone, but ceaplomb 发表于 2025-3-25 02:25:11
