Histology of repaired calvariae 4 and 8 weeks of postimplantation in vivo. (a) Hematoxylin and eosin staining of calvariae defects in the blank, CS-0%P24/nHA, CS-10%P24/nHA, CS-10%P24/nHA plus ADSC, CS-10%P24/nHA plus HUVEC, and CS-10%P24/nHA plus ADSC/HUVEC coculture groups. Red arrows show new blood vessel formation in or around the scaffolds. (b) Masson’s trichrome staining of repaired calvariae in each group. and 50 μm.
