The Study was conducted by the Sloan Center on Aging & Work at Boston College between November 2007 and September 2008 (Time 1: November 2007 to March 2008; Time 2: May 2008 to September 2008). The Center collaborated with 9 U.S. workplaces (12 departments) on this study.
Heart muscle cells can take approximately 20 years to completely renew themselves. Never Cells that cannot repair â Itâs unfortunate for many, but old age can take itâs toll on the eyes and brain.
Using these dating methods, it was inferred that fat cells (adipocytes) replace at a rate of 8Â±6% per year (BNID 103455). This results in the replacement of half of the bodyâs adipocytes in â8 years. A surprise arrived when heart muscle cells were analyzed. The long held dogma in the cardiac biology community was that these cells do not replace themselves.
