BIOMEDICINE: Repair by Satellite

satellite cells contribution to exercise mediated muscle hypertrophy and repair

satellite cells (scs) are the most abundant skeletal muscle stem cells. they are widely recognized for their contributions to maintenance of muscle mass, regeneration and hypertrophy during the human life span. these cells are good candidates for cell therapy due to their self-renewal capabilities and presence in an undifferentiated form. presently, a significant gap exists between our knowledg...

Autoimmune diseases, such as rheumatoid arthritis and multiple sclerosis, are complex disorders characterized by an inflammatory response against the body's own tissues. Recent findings reveal new insights into how these diseases are initiated and progress and the factors that contribute to their clinical symptoms. Such work also pinpoints potential new therapeutic targets including the integra...

This issue’s Biomedicine Select highlights new insights into the role of mitochondria in disease. Several new studies implicate abnormal mitochondria in the destruction of neurons of the substantia nigra, the cause of Parkinson’s disease (PD). Meanwhile, an elegant computational approach has enabled identification of candidate genes for several mitochondrial diseases including the mitochondrial...

Angiogenesis (the recruitment and formation of new blood vessels) may be a limiting step in the growth of tumors. Recent work in animal models of human cancer suggests that even transient angiogenic signals can irreversibly block tumor dormancy, promoting tumor growth. Another report concludes that the production of an-giogenic factors may result from activation of a signaling pathway in the in...
