Blue-green microalga Spirulina platensis (SP) gained more attention for its antioxidant and/or anti-inflammatory properties magnifying its beneficial effects as a feed additive and for cosmetic and biomedical applications. This study was performed to examine the impact of SP on the cutaneous wound and burn healing and to develop an understanding of the correlation between the sequelae of wound healing and the molecular expression patterns of wound healing-related genes as angiogenic basic fibroblast growth factor (bFGF) and vascular endothelial growth factor (VEGF) and fibrosis-related genes as transforming growth factor-β (TGF-β) and α-smooth muscle actin (α-SMA) in rat wound models. To achieve these goals, two experiments were performed on 32 Wister male rats that were divided into 4 groups of 8 rats each. Each experiment was represented by 2 groups; the control group (CG) and the Spirulina group (SG). A full-thickness wound (1.5× 1.5 cm) and burn wound (2× 2 cm) were made on the back of each generally anaesthetized rat and the areas of wound and burn were measured on days of
