Improving early in vivo osseointegration and removing residual cancer cells after tumor removal requires the development of novel bone implants with osteogenic and anti-cancer properties. Here, curcumin and vitamin D3 (Cur/VitD3) are loaded into calcium phosphate (CaP) matrices to improve in vivo osteogenesis and inhibit the proliferation of human osteosarcoma cells. Patient-specific, 3D-printed tricalcium phosphate (TCP) loaded with Cur/VitD3 increases the viability of in vitro osteoblast cells after 11 days. When delivered in combination, Cur/VitD3 loaded hydroxyapatite (HA)-coated Ti64 implant promotes new bone formation by 2.7-fold compared to the control after 6 weeks. This delivery system also decreases osteosarcoma cell viability relative to the 3D-printed TCP after day 11, indicating its anti-cancer properties. These findings contribute to the understanding of multifunctional CaP bone grafts to improve early osteogenesis after severe bone trauma and suppress the proliferation of osteosarcoma cells after tumor resection surgery.

Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
