We propose that the noncell-autonomous effects of Spemann's organizer on dorsoventral patterning are executed in part by diffusible signals that directly bind to and neutralize ventral BMPs during gastrulation.

我们提出，施佩曼组织器对背腹式的非细胞自发功能，有部分是通过原肠胚形成过程中，直接结合和抵消腹部BMP的扩散性信号所发挥的。

Combining Chinese practical situation and according to the analyses, there are some main conclusions made as following: 1. If the price elasticity of cocoon supply is over that of cocoon demand, the automatic fluctuation of the cocoon price would be emanative, which can cause the cyclical abnormal fluctuation and serious imbalance of cocoon market.
