Fig. 2. CD133+ cells are restricted to the
2ß1hi population and are largely quiescent. Basal cells were selected for
2ß1hi and
2ß1low expression. (A)
2ß1hi population labelled with antibodies to CD133 (red) and basal cell marker 34ßE12 (green). Co-localization (yellow/orange; yellow arrow). Scale bar: 5 µm. (B,C) Graph of
2ß1hi population (B) and
2ß1low population (C) labelled with anti-CD133 antibody (shaded area) and analysed by flow cytometry. Isotype control is depicted as a solid black line. (D) Dot-plot showing flow cytometric analysis of basal cells double-labelled with anti-CD133 (APC) and Ki-67 (FITC) from a representative experiment (n=3).
