The fraction, X2, of a population of D. discoideum cells competent to relay an aggregative signal has been measured as a function of time, t, spent in interphase. X2(t) is less than 0.I up to 5 h, increases slowly to 0.4 by 8 h 20 min, and saturates at I by 10 h. The hypothesis that cellular interactions might enhance X2(t) was tested by mixing populations of cells set into interphase at different times. No interactions were found. External stimulation did not affect X2(t).
已测定盘基网柄菌细胞群体中能够传递聚集信号的部分X2随处于分裂间期的时间t的变化情况。在5小时之前，X2(t)小于0.1，到8小时20分钟时缓慢增加至0.4，并在10小时时达到饱和值1。通过混合在不同时间进入分裂间期的细胞群体，对细胞间相互作用可能增强X2(t)这一假设进行了检验。未发现相互作用。外部刺激不影响X2(t)。
