Introduction: Mesenchymal stem cells (MSCs) counteract the decline of physiologic functions but their regenerative power decreases with age. In particular osteogenic differentiation capacity of MSCs has been shown to decrease with age thereby contributing to slowed down bone formation and osteoporosis. While much is known about cellular aging of MSCs, little is known about extrinsic factors influencing their functionality. Here we set out to identify circulating factors of the...

Introduction: Research on biomaterials for bone regeneration generates a plethora of new biomaterials requiring evaluation with reliable and comparable methods of biocompatibility and functionality for clinical translation. To reduce the burden of in vivo assessment, there is a need for refined in vitro assays that are predictive of in vivo outcomes. This retrospective study correlated in vitro results with in vivo outcomes observed...

Levels of circulating vesicular microRNA-31 increase with age as well as in the case of osteoporosis and inhibit osteogenic differentiation capacity of mesenchymal stem cells

Aging is a complex process that results in the decline of physiologic functions due to accumulation of damage in cells and tissues. Mesenchymal stem cells (MSCs) counteract this decline but their regeneration capacity decreases with age. In particular osteogenic differentiation potential of MSCs has been shown to decrease with age thereby contributing to slowed down bone formation and osteoporosis. While much is known about cellular aging of MSCs, little is known about factors...
