Platelet-derived endothelial cell growth factor (PD-ECGF) is a 45-kDa single chain polypeptide, which stimulates the growth and chemotaxis of endothelial cells in vitro and angiogenesis in vivo. Purification from human platelets and cDNA cloning of PD-ECGF disclosed that it is a novel type of angiogenic factor without sequence similarity to hitherto known proteins. PD-ECGF is present in human platelets as well as in placenta. Amino acid sequencing of PD-ECGF from human placenta revealed that the placental form has an additional 5 amino acids at the N-terminus. In cultured cells, it is produced by normal fibroblasts as well as some transformed cell lines. PD-ECGF lacks a hydrophobic signal sequence and remains inside the producer cells. PD-ECGF may act at sites of injury as a wound hormone and thus play an important role under several physiological and pathological conditions.

UI	MeSH Term	Description	Entries
D010920	Placenta	A highly vascularized mammalian fetal-maternal organ and major site of transport of oxygen, nutrients, and fetal waste products. It includes a fetal portion (CHORIONIC VILLI) derived from TROPHOBLASTS and a maternal portion (DECIDUA) derived from the uterine ENDOMETRIUM. The placenta produces an array of steroid, protein and peptide hormones (PLACENTAL HORMONES).	Placentoma, Normal,Placentome,Placentas,Placentomes
D011247	Pregnancy	The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.	Gestation,Pregnancies
D001792	Blood Platelets	Non-nucleated disk-shaped cells formed in the megakaryocyte and found in the blood of all mammals. They are mainly involved in blood coagulation.	Platelets,Thrombocytes,Blood Platelet,Platelet,Platelet, Blood,Platelets, Blood,Thrombocyte
