Purpose Of Review: This review summarizes recent investigations into the cellular and molecular effects of skeletal aging on the inflammatory response and stem cell function after fracture.
Recent Findings: Proper regulation of the inflammatory phase of fracture healing is essential. Aging is associated with chronic inflammation, which inhibits bone formation and promotes bone resorption. Osteogenic differentiation and anti-senescence pathways in skeletal stem cells are impaired in geriatric fractures. As the population ages, fragility fractures will continue to represent a significant clinical problem, which will require innovative clinical solutions. Skeletal stem cells in geriatric individuals demonstrate defects in anti-senescence pathways that lead to impaired osteogenic differentiation in vitro in humans. Small molecule-based therapies can partially reverse the aging phenotype. In the future, molecular- or cell-based therapies modulating either inflammatory cells or skeletal stem cells represent potential therapeutic targets to augment contemporary fracture healing interventions in osteoporotic or aging individuals.

Lacking of suitable fish muscle stem cell line has greatly hindered the fabrication of cell-cultured fish meat. Here, we established and characterized a spontaneously immortalized marine fish muscle stem cell line (EfMS) from brown-marbled grouper (Epinephelus fuscoguttatus), which could actively proliferate with good genetic stability and well maintain the stemness of myogenesis potential for over 50 passages. Taurine was found to be able to serve as a substitute of fish muscle extract in maintaining stemness.

Background: Skeletal muscle atrophy significantly affects quality of life and has socio-economic and health implications. This study evaluates the effects of entacapone (ENT) on skeletal muscle atrophy linked with oxidative stress and proteolysis.
Methods: C2C12 cells were treated with dexamethasone (Dex) to simulate muscle atrophy.

Objective: Aim: To determine the effect of cell therapy on the intensity of lipid peroxidation processes in the liver, kidneys and lungs of rats of different ages under conditions of experimental cranio-skeletal trauma (CST).
Patients And Methods: Materials and Methods: In the experiments, 129 white male Wistar line rats of different age groups were used: immature rats aged 100-120 days and weighing 90-110 g; mature rats aged 6-8 months and weighing 180-200 g; and old rats aged 19-23 months and weighing 300-320 g. In each age group, CST was modeled under thiopental sodium anesthesia.

Skeletal disorders pose significant challenges to health and quality of life, underscoring the critical need for innovative bone repair methods. Recent studies have spotlighted the promising role of extracellular vesicles (EVs) derived from bone marrow mesenchymal stem cells (BMSCs) in conjunction with biomimetic peptide (BP) WKYMVm (WK) for bone repair. This research leveraged a self-healing hydrogel as a carrier, effectively loading EVs and WK to enhance treatment efficacy.
