I wonder if BMP2 & PDGF have names that we’re familiar with. I checked the article, but didn’t see it.
“Two growth factors—bone morphogenetic protein 2 (BMP2) and platelet-derived growth factor (PDGF)—are currently approved by the Food and Drug Administration (FDA) to assist with bone healing.”
BMP2 has problems, but is used (injected, it seems) for spinal fusions and other bone work.

Platelet-derived growth factor seems to be used for a variety of occasions, also injected:

I think I’d prefer the PDGF.
