SpletPDGF, particularly PDGF-BB, is the strongest chemotactic and mitogenic agent for the fibrogenic cells of the liver. During liver injury, expression of this growth factor and its cognate receptor are highest in areas of greatest damage. PDGF is secreted in response to injury by platelets, Kupffer cells, stellate cells, and hepatic myofibroblasts. Splet12. dec. 2007 · Platelet-derived growth factor (PDGF)-BB is a homodimeric growth factor with a broad range of target cells, notably mesoderm-derived cells, such as pericytes and mesangial cells, but also ectoderm-derived glial cells and neurons. PDGF-BB binds to two distinct receptor tyrosine kinases denoted PDGF receptor (PDGFR)- α and – β [ 1 ].

"SpletPlatelet-derived growth factor (PDGF) is a family of cysteine-knot-type growth factors that are synthesized in several cells including the brain cells such as the neuronal progenitors, neurons, astrocytes, and oligodendrocytes. PDGF acts in both an autocrine and a paracrine manner and exerts active roles in embryonic development up until adulthood. " - Pdgf bb pericyte
