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

Figure 2

Numbers of liver cells in culture. Cells were cultured for 5, 15, and 28 days with (w) or without (wo) hydroxyapatite scaffolds embedded in hyaluronic acid gel (HyA), collagen-1 gel (C1), or no gel (NG), and cell numbers were determined by correlation with DNA concentration. Data are given as means from 6 biological repeats ± standard deviation.
