Figure 7. SMA (red) is used to indicate where distal EdU+ cells reside within the ductal system.
Before the chase period, all EdU+ cells remain within the duct. However, after the chase period, some EdU+ (sic LREC) become periductal. Additionally, there is an increased number of EdU positive cells (green) distal to the nipple after chase in the inguinal gland, as shown previously. EdU+ cells are indicated with white arrows in the colocalized images. The sections are counterstained with DAPI (blue).
