240-270 / 1000+ resultsresearch Differentiation and Apoptosis in Pilomatrixoma
Pilomatrixoma involves abnormal hair keratin production and cell death, causing debris and cysts.
research Polyclonal origin and hair induction ability of dermal papillae in neonatal and adult mouse back skin
Dermal papillae cells, important for hair growth, come from multiple cell lines and can be formed by skin cells, regardless of their origin or hair cycle phase. These cells rarely divide, but their ability to shape tissue may contribute to their efficiency in inducing hair growth.
