Due to a production error, the legend to Table was printed incorrrectly. The sentence:

^‡T test showed no significant differences (P > 0.05) between values.

should have read:

^‡T test showed significant differences (P < 0.05) between values.

Rates were determined by linear regression analysis of each MT analyzed over 5–20 displacements measured 2–5 s apart. Data are given as mean ± SD of the rates measured for each MT, with n = number of MTs and cells measured.
