Graphs showing the accumulation of various brush cell differentiation markers as ${\text{EGFP}}_{\mathit{Gfi}\mathit{1}b}^{+}$ cells mature during their migration up the crypt towards the villus (mean±S.E.M.). The data was derived from crypts isolated from 3 Gfi1b^EGFP/+ mice. The distributions were determined by scoring the following total numbers of ${\text{EGFP}}_{\mathit{Gfi}\mathit{1}b}^{+}$ cells: Dclk1⁺ (435), Krt18⁺ (386), UEA-I⁺ (626), and Ptgs1⁺ (283).
