Steady and Temporary Expressions of Smooth Muscle Actin in Hair, Vibrissa, Arrector Pili Muscle, and Other Hair Appendages of Developing Rats
The hair erection muscle, arrector pili, is a kind of smooth muscle located in the mammalian dermis. The immunohistochemical study using an antibody against smooth muscle alpha actin (SMA) showed that the arrector pili muscle develops approximately 1-2 weeks after birth in dorsal and ventral skin, but thereafter they degenerate. The arrector pili muscle was not detected in the mystacial pad dur...
متن کاملReport of a rare case of bullous mycosis fungoides
Mycosis fungicides (MF), on extremely rare occasions, can be associated with vesiculobullous eruptions. We describe a 74-year-old man with previous documented histopathologic diagnosis of poikilodermic type of MF who recently developed some flaccid acral bullae on erythemoatous MF plaque and normal skin. Histopathology and direct immunoflourscence studies revealed extensive lichenoid chan...
متن کاملA case of acquired smooth muscle hamartoma on the sole.
A smooth muscle hamartoma is a benign proliferation of smooth muscle bundles within the dermis. It arises from smooth muscle cells that are located in arrector pili muscles, dartos muscles, vascular smooth muscles, muscularis mammillae and the areolae. Acquired smooth muscle hamartoma (ASMH) is rare, with only 10 such cases having been reported in the English medical literature to date. Most of...
متن کاملAndrogenetic alopecia: new insights into the pathogenesis and mechanism of hair loss
The hair follicle is a complete mini-organ that lends itself as a model for investigation of a variety of complex biological phenomena, including stem cell biology, organ regeneration and cloning. The arrector pili muscle inserts into the hair follicle at the level of the bulge- the epithelial stem cell niche. The arrector pili muscle has been previously thought to be merely a bystander and n...
متن کاملThe Basement Membrane of Hair Follicle Stem Cells Is a Muscle Cell Niche
The hair follicle bulge in the epidermis associates with the arrector pili muscle (APM) that is responsible for piloerection ("goosebumps"). We show that stem cells in the bulge deposit nephronectin into the underlying basement membrane, thus regulating the adhesion of mesenchymal cells expressing the nephronectin receptor, α8β1 integrin, to the bulge. Nephronectin induces α8 integrin-positive ...
