[ad_1] Angiogenesis, the complex set of processes by which new blood vessels are produced, becomes less efficient with advancing age. One important consequence is a loss of capillary density, which has a range of detrimental effects on tissue function, particularly in energy-hungry tissues such as the brain and muscle. Regeneration from injury is also … Read more
[ad_1] This article serves as a high level overview of the present state of bioprinting of three-dimensional sections of living tissue. The field has stalled at the hurdle of vascularization for more than a decade now; it has proven to be challenging to make the leap from tiny functional organoid tissues to something larger. … Read more
[ad_1] Researchers here identify a mechanism by which the practice of calorie restriction promotes muscle stem cell function, and thus repair and maintenance of muscle tissue. In animal studies calorie restriction is shown to produce both (a) a short-term effect associated with improved regeneration, and (b) a long-term effect in the sense of slowing … Read more
