Identification and maintenance culture of mouse ABSCs. A Characterization of the cells in colonies. Most were p63/Krt5 double-positive cells (scale bar, 100 μm). B Morphological manifestations of mouse ABSCs during maintenance culture. Brightfield images show that mouse ABSCs can maintain the formation of stem cell colonies during passage, and cells within the clones are in a cuboidal or cobblestone shape and retain cell–cell contact
