Figure 1From: Effect of troglitazone on tumor growth and pulmonary metastasis development of the mouse osteosarcoma cell line LM8 Effect of TGZ on cell morphology and PPARγ expression. (A) Subconfluent LM8 cells were treated with or without 50 μM TGZ for 3 days, fixed with ethanol, and stained with HE. The values given in the photographs represent the ratio of the number of spindle-shaped cells to the number of total cells and are the means ± SE for five fields. Magnification: ×200. (B) Subconfluent LM8 cells were treated with or without 50 μM TGZ for 3 days, and the expression of PPARγ was examined by immunofluorescence staining (magnification: ×200) and Western blot analysis.Back to article page
