Figure 4: Circulating ALDH

(A to C) The frequency of circulating ALDHhiSSCmid cells co-expressing CD34 with the macrophage scavenger receptor (CD68) was decreased in patients with T2D compared with control subjects. (D to F) The frequency of circulating ALDHhiSSCmid cells co-expressing CD68 with the M1 macrophage–associated marker CD80 was equal in patients with T2D compared with control subjects. (G to I) The frequency of circulating ALDHhiSSCmid progenitor cells co-expressing CD68 with the M2 macrophage–associated marker CD163 was decreased in patients with T2D compared with control subjects. Values are mean ± SEM. *p < 0.05 with the Student's t-test. Other abbreviations as in Figure 1.
