Cell Fractionation of Anterior Pituitary Glands from Beef and Pig
Fresh anterior pituitary glands from beef and pig were separated by differential centrifugation into subcellular fractions. Nuclei and debris were obtained at 700 g for 15 minutes, secretory granules at 7000 g for 20 minutes, mitochondria at 34,000 g for 15 minutes, and microsomes at 78,000 g for 3 hours. Electron micrographs were taken of the individual fractions. Each fraction was analyzed fo...
متن کاملN-terminal amino acid analysis of growth hormones from human, monkey, whale, and beef pituitary glands.
The isolation of growth hormone (somatotropin) from human, monkey, and whale pituitary glands has recently been reported (l-3). Preliminary studies on the hormone proteins from these species have suggested that phenylalanine is their sole N-terminal amino acid residue (l-3), in contrast to the two N-terminal residues, alanine and phenylalanine, which have been reported for the bovine somatotrop...
متن کاملPituitary Hormones: Posterior Pituitary & Anterior Pituitary
The pituitary gland, also known as hypophysis, is a small pea-sized gland about 1 cm in diameter and 0.5 to 1 gram in weight. The pituitary gland resides in a small bony cavity situated at the base of the brain, known as sella turcica, and a pituitary stalk (infundibulum) maintains a connection between the pituitary gland and hypothalamus. The secretion of hormones by the pituitary gland is und...

متن کاملMitogenic activity of pituitary hormones on cell cultures of normal and carcinogen-induced tumor epithelium from rat mammary glands
Cell suspension containing normal or tumor epithelium were readily obtained by enzymatically digesting rat mammary glands from perphenazine-treated (prolactin-hypersecreting) cycling, female virgin animals or hormone- responsive mammary tumors from animal treated with dimethylbenzanthracene. Cell suspensions were fractioned into predominantly epithelial and predominantly stromal cells by their ...
