THE SMOOTH MUSCLE CELL

The Smooth Muscle Cell

These studies have examined the ability of smooth muscle cells from developing aorta of the prepubertal rat to utilize amino acids in the synthesis and secretion of connective tissue proteins. Prepubertal rats, previously given either an alcohol carrier or estradiol-17-beta, were each given an intravenous injection of proline-(3)H. The animals were sacrificed after 15 and 30 min, and 4 hr. Ligh...

The smooth muscle cell. III. Elastin synthesis in arterial smooth muscle cell culture

Primate arterial smooth muscle cells and skin fibroblasts were examined for their ability to synthesize elastin in culture. In the presence of the lathyrogen beta-aminopropionitrile, the smooth muscle cells incorporate [3H]lysine into a lysyl oxidase substrate that was present in the medium and associated with the cell layer. A component having a mol wt of 72,000 and an electrophoretic mobility...

UnTEThering (smooth muscle) cell plasticity.

C ellular plasticity has become the subject of intense research, with perhaps the greatest example provided by the recent Nobel Prize winners Drs Yamananka and Gurdon and the demonstration that terminally differentiated fibro-blasts can be coaxed into assuming an embryonic stem cell-like fate. Emerging evidence suggests that plasticity inherent in cells may be hijacked in the progression of dis...

The effect of adrenomedullin and proadrenomedullin N- terminal 20 peptide on angiotensin II induced vascular smooth muscle cell proliferation

Objective(s): The study aimed to investigate the effects of adrenomedullin (ADM) and proadrenomedullin N- terminal 20 peptide (PAMP) on angiotensin II (AngII)-stimulated proliferation in vascular smooth muscle cells (VSMCs). Materials and Methods: Thoracic aorta was obtained from Wistar rats and VSMCs were isolated from aorta tissues and then cultured. In vitro cultured VSMCs were stimulated w...
