FIG. 4.
Phase-contrast microscopic photographs of adipocytes in 2 weeks after differentiation defined medium only (control) (A), PGF2α (B), latanoprost (C), travoprost (D), bimatoprost (E), and tafluprost (F). Differentiated cells showed marked lipid accumulation and round cell morphology (arrow), whereas undifferentiated cells retained their spindle-like and fibroblastic appearance throughout the duration of the experiment (arrow head, ×100).
