Abstract excerpt
To determine if bone morphogenetic protein-2 (BMP-2) can induce the endochondral maturation of resting zone (RC) chondrocytes, confluent fourth-passage cultures of these cells were pretreated for 24, 36, 48, 72, or 120 h with recombinant human BMP-2. At the end of pretreatment, the media were replaced with new media containing 10(-10)-10(-8) M 1,25-(OH)2D3 or 10(-9)-10(-7) M 24,25-(OH2)D3 and the cells incubated...
