Most neuroepithelial cells in the embryos of Xenopus laevis and Notophtalmus viridescens become round upon entering into mitosis. However, many maintain their elongated form, or show long cytoplasmic processes, during mitosis. It therefore seems possible that, in these species, two groups of microtubules are present during mitosis: cytoplasmic microtubules and mitotic microtubules.
非洲爪蟾和绿红东美螈胚胎中的大多数神经上皮细胞在进入有丝分裂时会变圆。然而，许多细胞在有丝分裂期间保持其细长形态，或显示出长的细胞质突起。因此，在这些物种中，有丝分裂期间似乎可能存在两组微管：细胞质微管和有丝分裂微管。
