Open-Porous Hydroxyapatite Scaffolds for Three-Dimensional Culture of Human Adult Liver Cells

Figure 4

Immunocytochemistry of liver cell cultures. Liver cells were cultured for 28 days and stained, and images were taken by confocal microscopy. (a) Cells cultured in collagen-1 gel; (b) cells cultured in collagen-1 gel on hydroxyapatite scaffold; (c) cells cultured on hydroxyapatite scaffold only. Blue = DAPI, red = phalloidin, and green = CK19.
