PHC3 and Stroke: Indeed, triple immunofluorescent staining with antibodies against PH3, a marker of the G2/M phases of proliferating cells [23], revealed that stroke increased PH3+ cells with single γ-tubulin+ basal body at the center of β-catenin+ pinwheel structure and these cells were in the mitotic telophase as evident by a pair of PH3+ nuclei (Fig. 2).
