Fig. 7. Measurement of mpc apoptosis. (A) Example of flow cytometric analysis of mpc apoptosis in co-cultures of mpcs with MPs. CD14 labelling is used to discriminate MPs from mpcs. The apoptotic mpc population is gated in red: annexin V+ CD14- cells and DIOC-6- CD14- cells. (B) Example of spontaneous (dotted lines) and STS-induced (continuous lines) apoptosis in mpc cultures. (C) Expression of CD14 by CD45 cells in co-cultures of mpcs with MPs.
