Slime mold (Moens, 1976)L1 2.1 ± 0.1 (n= 3)L2 − L1 = 2.8
L24.9 ± 0.3 (n = 6)
Rat kangaroo (PtK1 cells;Armstrong and Snyder, 1989)L1 13.2 (n = 5)L2 − L1 = 4.2
L2 17.4 (n = 5)
Rat kangaroo (PtK1 cells; Snyder et al., 1986)L1 12.2 (n ≥ 6)L2 − L1 = 4.2
L2 16.4 (n ≥ 6)

Data presented as means ± se, which were calculated based on the cited publications for spindles with similar lengths, or as mean only according to the publications. (n = no. of spindles examined). In the case of S. cerevisiae, values of the extra-long spindles at late stages of cell division (telophase/cytokinesis) were not included here.
