Rejuvenation of aged progenitor cells by exposure to a young systemic environment. Physiol.

Long-term high-level exercise promotes muscle reinnervation with age.

3, 226–237 (2007). Comp. The less oxidative environment may encourage the survival of more of the activated satellite cells so that they can participate in muscle repair.

Med. the best experience, we recommend you use a more up to date browser (or turn off compatibility mode in A., Gurley, C. M., Gaddy, D., Knox, M., Fluckey, J. D., et al. Nevertheless, some studies have not found a loss of satellite cells in old muscles as compared to muscles from young animals (van der Meer et al., 2011b), but this is complicated by the fact that although muscle mass/bodyweight was lower in the old animals, the absolute muscle mass was similar in young and old animals. Sci. 591, 3789–3804. Fiber typing in aging muscle. 292, E151–E157. Chem. Schultz, E., Gibson, M. C., and Champion, T. (1978). Stretch overload-induced satellite cell activation in slow tonic muscle from adult and aged Japanese quail. bFGF and LIF signaling activates STAT3 in proliferating myoblasts. The satellite cell in male and female, developing and adult mouse muscle: distinct stem cells for growth and regeneration. Skeletal muscle hypertrophy following resistance training is accompanied by a fiber type-specific increase in satellite cell content in elderly men. J. Physiol.

In the context of treating sarcopenia, it is important to note that not all changes in diet that might slow muscle loss, necessarily affect satellite cell function.

(2014). Single-cell analysis of regulatory gene expression in quiescent and activated mouse skeletal muscle satellite cells. Cytol. These data suggest that although ROS production was higher in isolated satellite cells from aged muscles, there was not a marked reduction in mitochondrial function of the remaining mitochondria (Minet and Gaster, 2012). doi:10.1093/gerona/gln050, Verdijk, L. B., Koopman, R., Schaart, G., Meijer, K., Savelberg, H. H., and van Loon, L. J. 36, 608–617. (2011). Population of muscle satellite cells in relation to age and mitotic activity. doi:10.1016/j.mam.2011.10.001, Xu, Z., Huang, G., Gong, W., Zhou, P., Zhao, Y., Zhang, Y., et al. doi:10.1016/j.ydbio.2004.08.015, Olguin, H. C., Yang, Z., Tapscott, S. J., and Olwin, B. This review discusses data pertaining to the satellite cell responses and function in aging skeletal muscle, and the impact that three compounds: resveratrol, green tea catechins, and β-Hydroxy-β-methylbutyrate have on regulating satellite cell function and therefore contributing to reducing sarcopenia or improving muscle mass after disuse in aging.

Phillips, S. M., Tipton, K. D., Aarsland, A., Wolf, S. E., and Wolfe, R. R. (1997). The lower regenerative potential of aged muscles is correlated nicely with the decline in satellite cell function (Jang et al., 2011; Chakkalakal and Brack, 2012; Collins-Hooper et al., 2012; Bernet et al., 2014) and a reduction in the Pax7 pool of myogenic stem cells (Collins et al., 2007).

The regulation of Notch signaling controls satellite cell activation and cell fate determination in postnatal myogenesis. Biol. Development 138, 3647–3656. (Lond.) Age (Dordr.) Sci. Biophys. Pax7 is critical for the normal function of satellite cells in adult skeletal muscle. 28, 463–499.

In adults, satellite cells can be recruited to supply myoblasts for routine muscle fibre homeostasis, or for the more sporadic demands of … CAS  Describe the function of oligodendrocytes. Satellite cells that are isolated from sarcopenic muscles from old rodents and humans have a greater propensity for apoptosis and greater levels of apoptotic signaling proteins (Fulle et al., 2012, 2013).
