Masson's trichrome staining for collagen in control and A. squamosa treated wound tissues from first and second week, respectively (magnification 20x). Control (a) shows collagen fibers with incomplete epithelialization whereas (b) treated tissue shows dense collagen deposition. In the second week, control (c) depicts thin collagen layer at the wound site and (d) treated tissue shows complete epithelialization with uniform collagen deposition. IE: incomplete epithelialization, CE: complete epithelialization, E: epithelialization, BV: blood vessels, and C: collagen. Scale bar: 50 μm.
