Mouse study shows aging muscle leaves a molecular fingerprint in its supporting matrix

Aging is often described done what we tin spot and feel: weaker muscles, reduced mobility and slower recovery. But down these disposable changes are deeper biologic shifts successful cells, tissues and the molecular structures that enactment them. A caller survey published successful BMC Genomics offers a person look astatine 1 of these hidden layers of aging: the extracellular matrix, oregon ECM, successful skeletal muscle.
