Confluent cultures of undifferentiated preadipocytes (a) and mature adipocytes after differentiation for 15 days (b,c). The high amount of fat droplets, visible as light globules (b,c), demonstrates the cells being differentiated to mature adipocytes. Cells were photographed with 100x (a,b) and 400x (c) magnification.
