sup][4],[5],[6] It had been reported that ectopic expression of NuMA, including interference of NuMA by microinjection of its antibodies,[sup][7] mutations at the spherical domains at the amino or carboxyl terminal domains,[sup][5] and overexpression of NuMA,[sup][8] would bring on aberrant spindles, such as multipolar spindles.
The oocytes were incubated in microdrops of M16 medium (M7292; Sigma-Aldrich, USA) containing 200 [micro]M IBMX covered with mineral oil (Sage, USA) at 37[degrees]C under 5% CO2 in atmosphere until microinjection was conducted.
