MSC proliferation on the BCP and nHA-coated BCP scaffolds. (A) Percentage of living cells, P _Live. (B) Attachment density, C _Attach. P _Live did not differ significantly between the BCP and nHA-coated BCP groups at either day 1 or day 14, but did increase significantly from day 1 to day 14 on both scaffold types. From day 1 to day 14, C _Attach of MSCs on BCP and nHA-coated BCP scaffolds increased 5.7- and 7.6-fold, respectively. Data are given as mean ± SD, and n = 12 with dissimilar letters indicating a significant difference (P < 0.05).
