a Diagram of the placement of the subcutaneous pockets and gel implants. Animal sample size was n = 2, each animal had n = 4 samples implanted for n = 4 per condition. Created in BioRender. Daso, R. (2025) https://BioRender.com/6gg4lm0 Photos of b. The alginate gel control and c. TR-CP/alginate composite gel in their subcutaneous pocket 2 weeks post implantation. d–i Hematoxylin-eosin staining of skin sections with implanted gels at 1 and 2 weeks post implantation where G indicates gel area visible as dark purple color and arrow points to microvasculature observed in the TR-CP/alginate samples, which appear as small ovoid vessels containing red-stained erythrocytes. Scale bar d, e, g, h = 1.5 mm, f, i = 50 µm. The micrographs pictured (d-i) were 1 of 2 biological samples per gel per time point.
