Biomimetic Nanomedicine for Aging‐Impaired Bone Regeneration: From Microenvironmental Dysfunction to Precision Therapeutics

open access: yesAdvanced NanoBiomed Research, EarlyView.
Aging disrupts the cellular, immune, vascular, and neural processes required for bone regeneration. This review connects these pathological barriers with biomimetic nanomedicine design, highlighting strategies for cellular rejuvenation, immune modulation, vascular regeneration, and neuro–bone coupling.

Biology of RANK, RANKL, and osteoprotegerin [PDF]

open access: yesArthritis Research & Therapy, 2007
The discovery of the receptor activator of nuclear factor-kappaB ligand (RANKL)/RANK/osteoprotegerin (OPG) system and its role in the regulation of bone resorption exemplifies how both serendipity and a logic-based approach can identify factors that regulate cell function. Before this discovery in the mid to late 1990s, it had long been recognized that
