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]

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 ...
Histopathologically, FMTs consist of neoplastic connective tissue cells which have differented into cells that have microscopic appearances resembling fibroblasts and/or myofibroblasts. The fibroblastic cells are characterized as spindle-shaped cells with inconspicuous nucleoli that express vimentin , an intracellular protein typically found in ...
Fibroblasts from different anatomical sites in the body express many genes that code for immune mediators and proteins. [16] These mediators of immune response enable the cellular communication with hematopoietic immune cells. [17] The immune activity of non-hematopoietic cells, such as fibroblasts, is referred to as “structural immunity”.
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 ]
These cells create a stromal niche for cancer cells and especially cancer stem cells, where they employ both paracrine and direct cell-contact to maintain stemness in cancer stem cells. In turn, this enables these cancer stem cells to escape chemotherapy and radiotherapy, while the cancer-associated fibroblasts also create an environment that ...
The connective tissue of the lamina propria is loose and rich in cells. The cells of the lamina propria are variable and can include fibroblasts, lymphocytes, plasma cells, macrophages, eosinophilic leukocytes, and mast cells. [2] It provides support and nutrition to the epithelium, as well as the means to bind to the underlying tissue.
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 ...
