Visible-light-triggered BMP-2 release from enzymatically crosslinked marine collagen-alginate hydrogel blends enhances osteogenesis in dental pulp stem cells

{{output}}
Objectives: Achieving spatiotemporal control over osteoinductive signaling remains a key challenge in craniofacial tissue engineering. Conventional BMP-2 delivery from photocrosslinked hydrogels often leads to uncontrolled burst ... ...
