内容記述 | It has been reported that Paramecium proliferates slower when cultured under hypergravity. In order to gain an insight into the mechanism underlying the sensitivity to hypergravity, the proliferation under hypergravity was compared with that under lowering temperature or reduced nourishment, where cell proliferation rate is known to be reduced. Proliferation experiments was conducted under different conditions with three variables; gravity, temperature, and nourishment. In each experiment, control cells were grown under 1 G at 24 C with 100 percent nourishment through three experiments. In order to assess the proliferation under different conditions, the kinetic parameters of proliferation were obtained through a numerical analysis based the least squares fitting of the logistic growth equation. Maximum proliferation rate was reduced under hypergravity, lowering temperature and reduced nourishment. Saturation density was maintained under lowering temperature, while those were lower under hypergravity and reduced nourishment. Logistic parameter which was maintained under hypergravity became smaller under lowering temperature, and larger under reduced nourishment. It was also reported that hypergravity reduced the cell size of Paramecium. The maximum cell volume significantly decreased under hypergravity, while it tended to increase under lowering temperature and decrease under reduced nourishment. These results indicate that the mechanism of reduced proliferation rate under hypergravity is different from those under lowering temperature and reduced nourishment. | |||||
