Lack of evidence for GDF11 as a rejuvenator of aged skeletal muscle satellite cells
نویسندگان
چکیده
Recent high-profile studies report GDF11 to be a key circulating 'anti-aging' factor. However, a screen of extracellular proteins attempting to identify factors with 'anti-aging' phenotypes in aged murine skeletal muscle satellite cells did not identify GDF11 activity. We have been unable to confirm the reported activity of GDF11, similar to other laboratories offering conflicting data and describe our attempts to do so in this short take.

Restoring systemic GDF11 levels reverses age-related dysfunction in mouse skeletal muscle.
Parabiosis experiments indicate that impaired regeneration in aged mice is reversible by exposure to a young circulation, suggesting that young blood contains humoral "rejuvenating" factors that can restore regenerative function. Here, we demonstrate that the circulating protein growth differentiation factor 11 (GDF11) is a rejuvenating factor for skeletal muscle. Supplementation of systemic GD...
متن کاملIsolation and optimization of mice skeletal muscle satellite cells using preplating method and culture media substitution
Introduction: Satellite cells are known as the main regenerative cell type in skeletal muscles. Our study established a modified digestion and preplating method for the isolation of slow or weak adherent cells for the enrichment of satellite cells. Low-survival rate of these primary stem cells prompted us to address whether cell culture medium substitution might change cell viability status. M...
متن کاملUrsolic Acid Improve Skeletal Muscle Hypertrophy by Increasing of PAX7, Myod and Myogenin Expression and Satellite Cells Proliferation in Native Broiler Chickens
Ursolic acid (UA) is known as a naturally occurring triterpene pentacyclic compound in some medicinal herbs including savory that affects the skeletal muscle. In the current study, the effect of UA was evaluated on C2C12 cells and satellite cells (SCs) isolated from native broiler chicks. First in the in vitro experiment, the C2C12 cell line obtained from the Stem Cell Technology Research Cente...
متن کاملIs Growth Differentiation Factor 11 a Realistic Therapeutic for Aging-Dependent Muscle Defects?
This "Controversies in Cardiovascular Research" article evaluates the evidence for and against the hypothesis that the circulating blood level of growth differentiation factor 11 (GDF11) decreases in old age and that restoring normal GDF11 levels in old animals rejuvenates their skeletal muscle and reverses pathological cardiac hypertrophy and cardiac dysfunction. Studies supporting the origina...
متن کاملCorrection: GDF11/BMP11 activates both smad1/5/8 and smad2/3 signals but shows no significant effect on proliferation and migration of human umbilical vein endothelial cells
GDF11/BMP11, a member of TGF-β superfamily, was reported to rejuvenate heart, skeletal muscle and blood vessel architecture in aged mice. However, the rejuvenative effects of GDF11 were questioned recently. Here, we investigated the effects of GDF11 on smad and non-smad signals in human umbilical vein endothelial cells (HUVECs) and the effects of GDF11 on proliferation and migration of HUVECs a...
