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

Figure 3

Structural stability microcapsules. Thousands each of DPC-Ba and DPC-Ca microcapsules were assessed by determining change in structural integrity under an inverted microscope at 10 and 60 min after being stirred in flask (a). Cells inside the fragmented Ca microcapsules escaped (b). Cells were retained inside the membrane of Ba microcapsules, even after fragmentation (c). 1 mL of Ba and Ca microcapsules of 400 μm diameter were injected through 7#, 9#, and 16# pinheads, and integrated microcapsules were counted under a phase-contrast microscope (d). (Bar = 100 μm.)
