Aberrant Differentiation (IMAGE) Tokyo Medical and Dental University Caption A. ISCs undergo self-renewal and have the capacity to produce more differentiated epithelial cells, such as immature secretory epithelial cells. The balance between self-renewal and differentiation is strictly maintained in ISCs. B. In Irf2-/- mice, augmented IFN signaling causes aberrant differentiation of ISCs into immature secretory epithelial cells, that causes ISC reduction.
