Comparison of Calcium and Barium Microcapsules as Scaffolds in the Development of Artificial Dermal Papillae

Figure 6

Short-term study of DPC-Ca and DPC-Ba microcapsules transplanted into rat ears. Large hair follicles formed after Ca microcapsule implantation at weeks 1–4 (a, b, e, f, i, j, m, and n). At 2 weeks, large DP formed near the transplanted site without the surrounding DPC microcapsule (e, f). No abnormal hair follicle structures were found in Ba microcapsules at 1 to 2 weeks after transplantation (c, d, g, and h). At 3 to 4 weeks, Ba (k, l, o, and p) microcapsules produced large hair follicles but fewer compared with Ca (i, j, m, and n) microcapsules. (Bar = 100 μm.)
