Migration of cultured vascular cells in response to plasma and platelet-derived factors
TLDR
Results indicate that PDGF is the primary factor in serum responsible for the migration of cultured aortic smooth muscle cells and that PF4 is a critical factor required to induce the Migration of pericytes.Abstract:
Phagokinetic migration of cultured vascular cells was tested in response to human platelet-rich serum ('serum') and human platelet-poor plasma serum ('plasma'). The cell types tested included bovine aortic endothelial cells, human umbilical vein endothelial cells, human haemangiomal capillary endothelial cells, bovine adrenal microvascular pericytes, and bovine aortic smooth muscle cells. Human serum stimulated a significant increase in the rate of migration for all five cell types. Human plasma stimulated the endothelial cells to migrate but had no effect on the migration of pericytes or smooth muscle cells. Highly purified platelet-derived growth factor (PDGF) stimulated dose-dependent migration of smooth muscle cells causing a 50% increase in phagokinetic track area relative to controls. Neither pericyte nor endothelial cell migration was stimulated by PDGF. Rabbit antiserum to human PDGF completely blocked the smooth muscle cell migration induced by either 10% serum or 1 ng/ml pure PDGF. Purified platelet factor IV (PF4) stimulated migration of pericytes but not of smooth muscle cells nor endothelial cells. Sheep antiserum to human PF4 completely blocked the pericyte migration induced by either 10% serum or 1 microgram/ml pure PF4. These results indicate that PDGF is the primary factor in serum responsible for the migration of cultured aortic smooth muscle cells and that PF4 is a critical factor required to induce the migration of pericytes. Other factors present in both plasma and serum control the migration of vascular endothelial cells.read more

Pericyte Loss and Microaneurysm Formation in PDGF-B-Deficient Mice
TL;DR: Comparisons made between PDGF null mouse phenotypes suggest a general role for PDGFs in the development of myofibroblasts, and endothelial cells of the sprouting capillaries in the mutant mice appeared to be unable to attract PDGF-Rbeta-positive pericyte progenitor cells.

TL;DR: It is concluded that only a small fraction of smooth muscle cells in an artery proliferate in response to the injury stimulus, and do so shortly after injury, or not at all.

A method for producing specific antisera with small doses of immunogen.
TL;DR: The method has succeeded in producing specific antisera to the subunits of HCG and testosterone conjugates with one immunization of 20 to 100 μg of immunogen, and the potential of the method for producing specificantisers to glycoprotein and other hormones with limited amounts of purified material prompts this report.
