Pericytes and renal mesangial cells are some examples of modified myofibroblast-like cells. Myofibroblasts may interfere with the propagation of electrical signals [5] controlling heart rhythm, [6] leading to arrhythmia in both patients who have suffered a heart attack and in foetuses. Ursodiol is a promising drug for this condition. [7]
Parietal epithelial cell (PEC) Podocyte; Angioblast → Endothelial cell; Mesangial cell. Intraglomerular; Extraglomerular; Juxtaglomerular cell; Macula densa cell; Stromal cell → Interstitial cell → Telocytes; Kidney proximal tubule brush border cell; Kidney distal tubule cell; Connecting tubule cells; α-intercalated cell; β-intercalated ...
Pancreatic stellate cells (PaSCs) are classified as myofibroblast-like cells that are located in exocrine regions of the pancreas. [ 1 ] [ 2 ] PaSCs are mediated by paracrine and autocrine stimuli and share similarities with the hepatic stellate cell . [ 2 ]
Lipofibromatosis, a mixture of lipofibromatosis tumors with different gene abnormalities; [27] these tumors differ from lipofibromatosis-like neural tumors which have not been classified as fibroblastic and myofibroblastic tumors. Giant cell fibroblastoma [28] Dermatofibrosarcoma protuberans [29] Fibrous hamartoma of infancy [7]
Unlike the epithelial cells lining the body structures, fibroblasts do not form flat monolayers and are not restricted by a polarizing attachment to a basal lamina on one side, although they may contribute to basal lamina components in some situations (e.g. subepithelial myofibroblasts in intestine may secrete the α-2 chain-carrying component ...
IMT lesions typically consist of, and are defined by, myofibrolastic spindle cells, [7] i.e. specialized cells that are longer than wide, have a microscopic appearance that merges the appearances of fibroblasts and smooth muscle cells (see myofibroblast), occur in normal as well as tumor tissues, and in normal tissues are commonly designated ...
The normal fibroblast cells receive a hormone signal from nearby cancer cells, indicating that it must become activated, and is thus classed as a CAF. [2] It is unclear why normal fibroblasts transition into CAFs but it has been found that by adding transforming growth factor-β to fibroblasts in culture they start to display features of CAFs ...
The site of keratinocyte stem cells remains unknown but stem cells are likely to reside in the basal layer of the epidermis and below the bulge area of hair follicles. The fibroblast involved in scarring and contraction is the myofibroblast, [30] which is a specialized contractile fibroblast. [31] These cells express α-smooth muscle actin (α ...
