Figure 6. Analysis of FDC-P1 uptake of gangliosides G_M3 and G_D1a from AFT-024-cell-conditioned medium.

Results are expressed as the percentage of total radioactivity incorporated. FDc corresponds to myeloid progenitors isolated after co-culture submitted to different metabolic labelling protocols as described in the Experimental section. COC, metabolic labelling during the last 12 h of 48 h of co-culture; ST, metabolic labelling only of stromal cells prior to co-culture for 48 h; PDMP, metabolic labelling only of stromal cells and treatment of FDC-P1 cells with 10 μM PDMP prior to co-culture for 48 h in the presence of 10 μM PDMP; PREC, metabolic labelling only of myeloid precursor cells prior to co-culture for 48 h.
