Resilient Calvarial Bone Marrow Supports Retinal Repair in Type 2 Diabetes

Advanced Science, EarlyView.
Skull bone (calvarium) marrow in diabetic mice stay structurally intact and keeps making blood cells, unlike the bone marrow of the leg bones. The skull marrow is exposed to cerebrospinal fluid (CSF), which contains protective molecules called oxysterols.

Pearl‐Like Bioinspired Coating Enables Regulation of Mg Degradation for Osteoporotic Bone Repair

Advanced Science, EarlyView.
In this study, inspired by pearl architecture, we developed a layered Ca–P “brick” and Fn‐mimetic peptide “mortar” coating on Mg alloys. The Ca–P layer moderates corrosion and offers mineral cues, while the peptide enhances adhesion and regulates immune‐vascular responses.
