RESULTS: After 24 hours of preinduction, cells changed from spindle to polygonal or irregular, with many short rod-shape processes and 2-3 nucleoli. Whirlpool shape growth disappeared, and was disordered. After 1-3 hours of induction, cells gradually became round, with significant cell contraction, strong refraction, bipolar or pluripolar processes connected each other into a net. After 5 hours of induction, grades one and two branches were detected.

结果：预诱导24 h，胞体由原来的长梭形变成多角形或不规则形，伸出多个短棒状突起，可见2~3个核仁，细胞间漩涡状生长趋势消失，排列无规律；诱导1~3 h，细胞逐渐变圆，胞质收缩明显，折光性增强，双级或多极的突起互相连接呈网状；诱导5 h，突起出现一、二级分支。
