Figure 5From: Hydroxyapatite bioactivated bacterial cellulose promotes osteoblast growth and the formation of bone nodulesBC polymer with and without hydroxyapatite promotes ALP activity. Following culture onto BC polymers ALP activity was measured by alkaline phosphatase substrate p-NPP. Different levels of ALP activity were observed in the range of 5 to 9 mM with the hydroxyapatite rich BC polymers; compared with the BC polymer without hydroxyapatite. Data were presented as the mean + S.D. (n = 4).Back to article page
