WebIntroduction. Although both pericytes and vascular smooth muscle cells arise from the mural cell population and both contribute to vessel wall stability and tone (Kumar et al., 2024), these cells play critical but distinct roles in regulating vascular structure and remodeling.In smaller vessels and capillaries, pericytes cover and directly interact with the … WebMar 16, 2024 · According to the existing research, pericytes express α-smooth muscle actin (SMA), smooth muscle myosin, tropomyosin, nestin, vimentin, desmin, neuron glial …
WebIt also delayed the radiation-induced vascular damage accompanied by increased α-smooth muscle actin-positive pericyte coverage and blood perfusion. Moreover, RT significantly reduced the IL-12-induced levels of alanine aminotransferase in blood. However, it did not further improve the IL-12-induced anti-tumor effect on distant tumors.

In conclusion, our study represents the first detailed look at the transcriptomic landscape across idiopathic pulmonary arterial ... WebEnveloped in the basement membrane, pericytes have intimate association with endothelial cells which demarcates them from smooth muscle cells. In vitro studies suggest that basement membrane is produced by pericytes and endothelial cells ( …
WebMar 2, 2024 · Pericytes Are Not Adipocyte Progenitors Pericytes have been designated a source of white adipocyte progenitors ( Tang et al., 2008) and recent reports suggested that at least a subset of beige adipocytes is derived from smooth muscle ( Long et al., 2014 ).
WebApr 1, 2015 · However, elucidation of the mechanism by which this occurs is at an early stage, and further studies are needed to determine the chemotactic signals driving pericyte accumulation in the airway wall, as well as the ability of these cells to differentiate into a more smooth muscle cell-like phenotype. red big snakeWebMar 21, 2024 · Recent evidence suggests that capillary pericytes are contractile and play a crucial role in the regulation of microcirculation. However, failure to detect components of … red bijiliWebApr 13, 2024 · Notably, the hyperconstriction of blood vessels is pathological and is facilitated by smooth muscle and pericytes.
