Endothelial cells release ________ that stimulate smooth muscle contraction and accelerate the repair process.

Question

Quizplus · Accepted Answer

Endothelins are peptide molecules that are released by the endothelial cells, and they play a significant role in the regulation of vascular tone by stimulating smooth muscle contraction. They also promote cell growth and accelerate the repair process by stimulating cell proliferation and migration. Platelets are not released by endothelial cells; they are formed in the bone marrow and are involved in blood clotting. Histamines and heparins are also not released by endothelial cells but rather by mast cells and basophils, respectively. CSFs, or colony-stimulating factors, are signaling molecules produced by various cells in the body that regulate the production and function of different types of blood cells.
