Implementing BMP‐7 Chemically Modified RNA for Bone Regeneration with 3D Printable Hyaluronic Acid‐Collagen Granular Gels

open access: yesAdvanced Healthcare Materials, EarlyView.
This study developed 3D‐printable THA‐Col microgels for delivering BMP‐7 cmRNA. The key result is that hMSCs transfected on the biomaterials showed BMP‐7 secretion levels comparable to pre‐transfected hMSCs, therefore introducing a cmRNA‐activated matrix to promote bone healing.
