Another study injected PRP into the vertebrae of postmenopausal women with low bone density. CT scans showed improved bone formation in the PRP-treated areas after 6 months.PRP's potential for osteoporosis is thought to come from growth factors like PDGF, TGF-β, and IGF-1 which are concentrated in the platelets. These can recruit osteoblasts and stimulate new bone matrix formation.
