Pericytes are present in capillaries where proper adventitia and muscle layer are missing (thus distingushing this cell type from adventitial cells). They are relatively undifferentiated and may become fibroblasts, macrophages, or smooth muscle cells. pericyte BTO:0002441 cell of Rouget Pericytes are CD10-positive, CD13-positive, CD31-negative, CD45-negative, CD106-positive, CD117-negative, CD140-positive, CD144-negative, CD146-positive, CD271-positive, CD325-positive, NG2-positive, RGS5-positive, SMA-positive, and desmin-positive. A subpopulation is CD248-positive. They are also capable of producing angiopoietin 1, CXCL12, TGF-beta, and VEGF-A. pericyte adventitial reticular cell adventitial cell perictye pericyte of Rouget FMA:63174 CT Splenic Pericyte connective tissue cell mural cell perivascular cell Homo sapiens sequence collection lymph node vessel large intestine anal canal cecum mucosa colonic mucosa ileocecal valve heart retina eye rectum caecum vermiform appendix ascending colon transverse colon descending colon sigmoid colon anus red pulp of spleen umbilical artery gut-associated lymphoid tissue venule blood vessel capillary placenta medulla of lymph node umbilical vein dermis right cardiac atrium left cardiac atrium heart right ventricle heart left ventricle interventricular septum skin of body spleen subcutaneous adipose tissue capsule of lymph node trabecula of lymph node umbilical cord prostate gland connective tissue myenteric nerve plexus submucosa of anal canal submucosa of colon mucosa of anal canal chorionic plate vasculature of retina submucosa of cecum submucosa of appendix mucosa of appendix adventitia lamina propria of mucosa of colon muscularis mucosae of colon vascular system lamina propria of large intestine subserosa large intestine smooth muscle circular layer large intestine smooth muscle longitudinal layer muscle layer of colon splenic flexure of colon hepatic flexure of colon placenta blood vessel spleen pulp venule of lymph node chorionic plate blood vessel anchoring villus chorionic mesoderm (from chorionic plate) floating villus immature intermediate villus mature intermediate villus placental disc sheathed capillary stem villous vessel stem villus terminal villus villous capillary
