Growth Hormone-Releasing Peptide 6 Enhances the Healing Process and Improves the Esthetic Outcome of the Wounds

Figure 6

Microscopic aspect of the rabbits’ ears wounds. (a) Representative image of “nipple” in which, above the cartilage and the perichondrium, there is a prominent accumulation of extracellular matrix. (b) Representative image of the effect induced by the GHRP-6 intervention. Note the reduction of extracellular matrix accumulation within the injured area. The “flattening” aspect is indicated by the solid line arrow. The dotted arrows indicate that the elevation within the center of the scar is similar to the adjacent intact skin. Images suggest that GHRP-6 reduced the local hypercellularity associated with the cartilage cells response. H/E 10x magnification.
