Why injured bones do not heal as well with age?
A study published on March 18, 2019, by the Proceedings of the National Academy of Sciences (PNAS), found that increases in chronic inflammation, not the passage of time, is the main reason why injured bones do not heal as well with age. Note: Despite all advances in stem cells research and the application of these therapies in many countries all over the world, stem cells therapies are not legally approved yet in San Diego, Los Angeles, Chicago, Dallas, New York, Jacksonville, Seattle, Houston, San Francisco, Salt Lake City, Miami, Beverly Hills and other US cities. However, stem cell treatments are legal in Costa Rica.
