Bone morphogenetic protein 2 (BMP2)

The human bone morphogenetic protein 2 is a bone-growth regulatory factor well known to be a potent osteoinductive protein.

Characterization of BMP2's effects in cartilage regeneration (by KEYSTONE_A 2020)

BMP2 and VEGF inhibition promote expression of cartilaginous pathways on sorted skeletal stem-cell (SSC) in vitro (Figure 3). Skeletal stem-cells (SSCs) isolated from the articular surface, periosteum and bone marrow all produced higher amounts of cartilage with addition of BMP2 + sVEGFR1 when compared with addition of PBS only (Figure 4). For in vivo experiments, cotransplantation with BMP2 + sVEGFR1 can also promote cartilage formation (Figure 5).
