The role of nerve cell density in the regulation of bud production in hydra was examined. Animals with different rates of bud production were produced by altering the temperature, population density and illumination of their cultures. When the distribution of cell types was examined in animals with different rates of bud production, the density of nerve cells in those animals was found to be correlated with their rate of bud production. Transfer of animals from one environment to another resulted in immediate changes in the rate of differentiation of large interstitial cells into nerve cells. This suggests that the density of nerve cells may play a role in regulating the rate of bud production in hydra.
研究了神经细胞密度在水螅芽体产生调节中的作用。通过改变培养环境的温度、种群密度和光照,培育出了具有不同芽体产生速率的水螅。当检测不同芽体产生速率的水螅体内细胞类型的分布时,发现这些水螅体内神经细胞的密度与它们的芽体产生速率相关。将水螅从一种环境转移到另一种环境中,会导致大的间质细胞向神经细胞分化的速率立即发生变化。这表明神经细胞密度可能在调节水螅芽体产生速率中发挥作用。
