Experiments on decalcification and activation of osteoinductive ability, comparison between the osteogenesis of demineralized bone matrix in orthotopic and in heterotopic sites, and correlation between immune response to allograft of bone and osteoinductive activity of the graft, were reported in this paper. 1. Syngeneic deminerolized bone matrix and the mixture of DBM with bone ash or acid-soluble protein extracted from demineralization was implanted into muscle pouch of mice, subsequently, the inhibition of DBM osteoinduction by bone ash or acid-soluble protein was demonstrated with histological and by means of alkaline phosphatase assay.

Although we have not a tool to directly modulate the cellular Cdc42/Rac activity at present, nevertheless, from the abolish of BDNF-triggered attraction by either DN-Cdc42 and CA-Cdc42, we propose that an intracellular Cdc42 activity gradient may also be sufficient to determine the turning direction, say, filopodia extend preferentially at the higher Cdc42 activity side, and the growth cone turn towards this direction in the hence.

虽然我们目前还没有一个直接操纵细胞内 Cdc42或其下游分子活性的方法，但从 DN-Cdc42和 CA-Cdc42均阻断到 BDNF 和 ryanodine 的吸引作用来看，我们推测， Cdc42的活性梯度很可能也能够决定生长锥转动方向，即丝状伪足在 Cdc42活性高的一侧优先延伸，生长锥朝向该侧转动。
