basic FUNCTION	inducing bone formation in conjunction with transforming growth factor beta (TGFB1, TGFB2)
	pituitary secretory protein, playing an important role in the regulation of cellular growth
	may be modifiing the hypertrophic response to extrinsic factors such as hypertension and aortic stenosis
	its downregulation is a fundamental requirement for proper arteriogenesis
	important regulator of left ventricular mass through modulation of the TGF-beta pathway
	DSPP, MEPE, VCAN, OGN play complementary roles during odontogenesis
	may be a crucial humoral bone anabolic factor that is produced by muscle tissues
	may be an important factor produced by muscle-derived cells and secreted into blood that exhibits bone anabolic effects
	might play an important role in bone formation by osteoblasts at the well differentiated stage
