Rapamycin Inhibits the Growth and Collagen Production of Fibroblasts Derived from Human Urethral Scar Tissue

Figure 1

Primary culture of fibroblasts derived from human urethral scar tissue (FHUS). (a) Long, spindle-like cells surrounded the scar tissue after 1 week of tissue culture. Magnification: 40x. (b) A swirl-shaped arrangement of cells was evident after 3 weeks of tissue culture. Magnification: 40x. (c) Immunostaining for vimentin resulted in the staining of filaments within the cytoplasm, indicating that the cells were fibroblasts. Magnification: 400x.
