This 3 panel image displays meiosis in a mouse oocyte triple labelled for microtubules (panel 1 and green), phosphorylated-Transforming Acidic Coiled-Coil protein (TACC3; panel 2 and red), and nucleic acids (blue). This oocyte was injected with siTPX2-5h, a doublestranded siRNA against TPX2 (targeting protein for Xenopus kinesin-like protein, xklp2)and rescued with the coinjection of YFP-TPX2DN, a truncated version of TPX2, which lacks the 118 first amino acids.

Time-lapse images were acquired using a Photometrics CCD camera (CoolSnap HQ2) mounted on a Leica DMI600B microscope using a Leica HC PL APO 20X/0.7 NA objective enclosed in a thermostatic chamber (Life Imaging Services). Immunofluorescence methods can be found in the cited paper and in Brunet S. et al. (1999) J Cell Biol 146: 1–11.
