“…rhBMP-2, -4, and -7 are capable of stimulating the differentiation of DPSCs and form the regenerative dentin [69][70][71]. When reconstituted in a collagen gel drop and stimulated by microencapsulated and control-released BMP4, BMP7 and Wnt3a, postnatal dental epithelial and mesenchymal cells can orchestrate de novo formation of enamel-and dentin-like tissues in two integrated layers in vivo [72,73].…”
