Platelet-derived growth factors enhance proliferation of human stromal stem cells

Studies on new procedures for bone reconstruction suggest that autologous cells seeded on a resorbable scaffold can improve the treatment of bone defects. It is important to develop culture conditions for ex vivo expansion of stromal stem cells (SSC) that do not compromise their self-renewing and differentiation capability. Bone marrow SSC and platelet gel (PG) obtained by platelet-rich plasma provide an invaluable source for autologous...
