Pericytes, which are multi-potential stem cells, co-create the walls of the microvessels: capillaries, terminal arterioles and postcapillary venules. These cells are localized under the basement membrane, tightly encircling the endothelium. The most frequently mentioned molecular markers of pericytes include NG2 (neural-glial antigen 2), β-type platelet-derived growth factor receptor (PDGFRβ), smooth muscle α-actin (α-SMA), regulator of G protein signalling 5 (RGS5), the adhesion protein CD146 and nestin. Different functions in physiological processes are assigned to pericytes such as maintaining the integrity and senescence of endothelial cells, transregulation of vascular tone or the potential to differentiate into other cells. Probably they are also involved in pathological processes such as tissues fibrosis. In this review, we focus on the participation of pericytes in the process of blood vessel formation, the regeneration of skeletal muscle tissue and fibrosis. Strong evidence for pericytes' participation in endothelial homeostasis, as well as in pathological conditions such as fibrosis, reveals a broad potential for the therapeutic use of these cells. Targeted pharmacological modulation of pericytes, leading to blocking signalling pathways responsible for the differentiation of pericytes into myofibroblasts, seems to be a promising strategy for the treatment of fibrosis in the early stages.
