3D-printed shape memory scaffolds from Pickering emulsion for codelivery of exosomes and Mg²⁺ to promote bone regeneration

Key Points

• Enhanced bone regeneration was observed with 3D-printed scaffolds that delivered exosomes and magnesium.
• The scaffolds effectively used Pickering emulsion for improved structural stability and drug delivery.
• Assessment using exosomes and magnesium showed significant healing in bone tissue, indicating effective delivery mechanisms.
• This study highlights the potential for 3D-printed scaffolds in tissue engineering, warranting further exploration in clinical applications.
