Pericytes and glial cells are accessory cells of neurovascular networks, which have been reported to participate in scar formation after tissue injury. A pericyte extends along the long axis of a capillary, sending processes around its circumference. Pericytes lie within the basal lamina of the capillary. Pericytes help to regulate blood flow through capillaries and participate in blood vessel repair after injury. 2021-03-29 Pericytes are specialized mesodermal cells which line the blood vessels.

Primary histologic changes in diabetes: Thickened retinal capillary basement membrane; Selective loss of capillary pericytes; Microaneurysms 2003-06-01 R.B. Dettmeyer, in Encyclopedia of Forensic and Legal Medicine (Second Edition), 2016 Introduction. Forensic histopathology as a specialist field in its own right within forensic medicine has undergone an expansion in terms of its required application and, by adopting and applying modern methods of investigation, has gained in diagnostic importance. This is particularly true of the field of This contributed book discusses the recent updates and novel functions of pericytes. This book is helpful for cell biology graduate students, postdoctorants as well as researchers that work on the pericyte field and want to be updated in the multitude of roles of pericytes in health and disease.
Pericytes (Peri- around) are cells that lie close to the endothelial cells of blood capillaries and small venules into which the capillaries drain. They are a potential source of new fibroblasts and smooth muscle cells, and help to repair damage.

Star-shaped, their many processes envelop synapses made by neurons. In humans, a single astrocyte cell can interact with up to 2 million synapses at a time. Astrocytes are classically identified using histological analysis; many of these cells express the intermediate filament

Epicardium, myocardium and endocardium histology. Epicardium histology. Myocardium histology. Endocardium histology. What are the valves of the heart composed of? Hepatic Histology: Sinusoids. Sinusoids are low pressure vascular channels that receive blood from terminal branches of the hepatic artery and portal vein at the periphery of lobules and deliver it into central veins.
