FIG. 2.

Percentages of Oil Red O–positive cells. Cells were adipogenically induced for 2 weeks and stained for lipid vesicles. The dark columns represent cells with Oil Red O vesicles, whereas the light columns represent Oil Red O–negative cells counted in the corresponding samples. No Oil Red O–positive cells could be found in the uninduced control cells (data not shown) such as in induced Flp-In-3T3 cells. (Dark grey bars) adipocytes (%); (light grey bars) cells not differentiated (%).
