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

Figure 1

Scanning electron microscopy. Porous foamed hydroxyapatite scaffolds (a) were used for cell culture. After 28 days of culture, numerous cells attached to the scaffold could be observed in cultures with collagen-1 (b), whereas considerably less cells were attached to scaffolds in culture with hyaluronan (c).
