B) Paclitaxel treatment did not affect the number of EdU+ cells within the HF outer root sheath (ORS) following washout. In contrast, palbociclib treated HFs lacked EdU incorporation following drug washout (adjusted p value = 0.0001 [***]). The number of EdU+ cells was significantly decreased in the outer root sheath (ORS) of HFs dual treated with both paclitaxel and palbociclib (adjusted p value = 0.0021 [**]). Ordinary one-way ANOVA with multiple comparisons performed using N of 12-13 HFs from 3 patients. Values plotted represent the mean total number of cells counted per HF analysed. Error bars are standard error
