Growth factor releasing implants towards osseointegration. The histological sections of peri-implant bone around HA and VEGF-HA modified Ti implants. Optical micrographs of histological sections showed significantly thicker trabecular around VEGF-HA loaded Ti implants (b) than HA-coated counterparts (a) at 12 weeks within sheep tibiae. The yellow arrows indicate the newly formed blood vessels abundant around VEGF-HA loaded Ti implants. Reproduced with permission from ref. 99
