This result suggests that central spindle distributed cam may also involve in the regulation of furrow ingression 此现象说明分布在中区纺锤体的cam也参与调控了分裂沟的缢裂加深。

We found that either the abnormal central spindle structure or the absence of central spindle distributed cam could inhibit the furrow formation . it indicates that the central spindle distributed cam might involve in the regulation of furrow formation 我们发现中区纺锤体结构异常、中区纺锤体处cam的缺失均会影响分裂沟的形成，提示分布在中区纺锤体处的cam很可能参与调控了分裂沟的形成。
