Muscle tissue containing injected microspheres at low magnification. Tissue samples were retrieved and sectioned at day 2 (A, B) and day 50 (C, D). Multiple images were assembled to represent the entire region containing microspheres. The polymer used for microsphere fabrication was high MW (A, C) and low MW (B, D). Labels indicate polymer (P) and muscle tissue (M). Scale bar represents 1.7 mm.
