The term pericytes was later coined by Zimmermann in 1923. He demonstrated that pericytes were: a) present around capillar-ies in a wide range of species including fish, amphibians, reptiles, birds and mammals; b) continuous with smooth muscle cells of arteries and veins; c) highly branched with distinctive cytoplasmic

Pericytes are embedded in basement membrane , where they communicate with endothelial cells of the body's smallest blood vessels by means of both direct physical contact and paracrine signaling . [3] This video “Pericyte: Definition, Structure & Function” is part of the Lecturio course “Histology” WATCH the complete course on http://lectur.io/pericytes Pericytes are perivascular cells with multifunctional activities which are now being elucidated. The functional interaction of pericytes with endothelial cells (EC) is now being established, using current molecular and cytochemical techniques. The detailed morphology of the pericyte has been well de … We found a pericyte: endothelial cell ratio of 1:12.4 (+/-7.1), and a difference of alpha-smooth muscle actin expression between the subpapillary plexus and the microvessels of the Stratum reticulare.

Pericytes histology

Myoepithelial cells (sometimes referred to as myoepithelium) are cells usually found in glandular epithelium as a thin layer above the basement membrane but generally beneath the luminal cells. These may be positive for alpha smooth muscle actin and can contract and expel the secretions of exocrine glands.They are found in the sweat glands, mammary glands, lacrimal glands, and salivary glands. Human dermal pericytes express 3G5 ganglioside – A new approach for microvessel histology in the skin Peter Helmbold Department of Dermatology, Martin Luther University, Halle – Wittenberg, Halle, Germany 2017-08-22 Recent publications on 3-D histology 1.

Pericytes are emerging as the predominant source of the activated, matrix depositing, stromal cell population seen in progressive fibrosis. Further, pericyte activation leads to their detachment from the vasculature, triggers unstable microvasculature and leads to rarefaction.

Comparison between these two transplantation sites revealed the importance of vascular smooth muscle cells and pericytes in sustaining vascular and tissue integrity. 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.

Lymphatic circulation Lymph is fluid that drains from the extracellular space of tissues. This fluid normally forms as capillary fluid passes out of the vessels, and is composed of water, electrolytes, and lesser amounts of plasma proteins. 2011-07-30 · The histology of the cardiovascular system plays the main role in its function. The cardiovascular function consists of the heart, arteries, microvascular bed, veins and lymphatic vessels.

Loss of pericytes was associated with an overall reduction in tumor vascularity (Figure 2D-F). In contrast, the vasculature of organs not involved with tumor, including lung, heart, liver, and kidney, in imatinib-treated mice showed normal histology and no increase in apoptosis (not shown). Although pericytes associate with greater than 97% of tumor vessels, the association between pericytes, ECs, and matrix is abnormal [8, 53]. The importance of pericyte coverage may be in part due to survival factors produced by pericytes. After a brief historical background, we consider the following aspects of pericytes: A) Origin in embryonic vasculogenesis (mesenchymal stem cells, neurocrest and other possible sources) and in embryonic and postnatal life angiogenesis (pre-existing pericytes, fibroblast/ myofibroblasts and circulating progenitor cells).
