    Promoting Muscle Regeneration With an Immune Factor

    A paper published today in Nature Aging has shown that a macrophage-regulating factor has a significant impact on muscle regeneration. Healing slows with aging The researchers note two key reasons for the decline of regenerative abilities with aging. The first is stem cell exhaustion, the gradual depletion of stem cells and ensuing lack of functional […] More
