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

Figure 7

Long-term study of DPC-Ca microcapsules transplanted into rat ears and the histology of Ca microcapsules at different weeks. From 12 to 36 weeks, the number and size of large hair follicles decreased (a, b, c, d, e, and f). At 18 weeks, Ca microcapsules were found at the transplanted site, with no surrounding inflammatory cells (g). At 20 weeks, some inflammatory cells were around the microcapsules (h). At 36 weeks the number of inflammatory cells was reduced, with fibers around the microcapsules (i). (Bar = 100 μm.) Red circle: microcapsules and formed HFs. Blue circle and arrow: microcapsules surrounded associated with inflammatory cells.
