EM examination of DCs originating from DP and SP HPCs.

DCs were sorted as indicated in the legend of Figure 5, from 9 day cultures under the standard condition with TGF-β1 added from culture day 0. Both DP HPC-derived (A) and SP HPC-derived (B) DCs present BGs (arrows). Note that typical cytoplasmic rod-shaped BGs, located at the vicinity of the Golgi apparatus, are present in DP HPC-derived DCs; in SP HPC-derived DC BGs are predominantly formed by a sandwiching process of the plasma membrane. Bars represent 200 nm. Data are from 1 of 2 experiments.
