basic FUNCTION	potent mitogen for cells of mesenchymal origin, also involved in transformation process
	potent negative regulator of smooth muscle cell (SMC) differentiation
	might be involved in the activation of primordial follicles
	growth factor involved in the recruitment and function of pericytes
	PDGFB signaling in trophoblasts is a key component of the unique placental hematopoietic microenvironment that protects hematopoietic stem/progenitor cell (HSPC) from premature differentiation
	induces senescence and transformation in normal human fibroblasts, but has a limited ability to induce senescence
	mitogen for hepatic stellate cells (HSC)

CELLULAR PROCESS	cell life, proliferation/growth

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

signal transduction

cell to cell signaling

a component

homodimerizing or heterodimerizing with PDGFA,(PDGFBB or PDGFAB)

INTERACTION

DNA

RNA

small molecule

protein	PDGFRA, PDGFRB
	XLKD1
	PDGFB may regulate THBD expression in VSMCs during vascular remodelling
	SERPINA12 significantly inhibited PDGFB-induced smooth muscle cells (SMCs) migration
	PDGFB-induced activation of MAPK14 was significantly suppressed by SERPINA12
	SF1 antagonizes PDGFB-induced growth and dedifferentiation of vascular smooth muscle cells
	LAMTOR5 upregulates PDGFB via activating transcription factor Sp1 to promote proliferation of breast cancer cells
	angiogenesis is stimulated by KLK12 acting via a PDGFB-dependent paracrine pathway
	LHX2 promotes tumor growth and metastasis by inducing autocrine and paracrine PDGFB signaling
	NOTCH2 inhibits PDGFB-dependent proliferation and its expression is decreased by PDGFB
