as stated in title, for example, why do red blood cells live and die in a matter of a few months, but cardiac and oocyte cells last for up to 50 years? i understand it has to do with telomeres somewhat, but vaguely. can anyone elaborate?
In: 24
Certain human cells live longer than others due to factors like their functions and the presence of telomeres, which protect against cellular aging. For example, neurons and heart muscle cells are long-lived because they don’t undergo frequent cell division, while skin cells and blood cells have shorter lifespans due to their rapid turnover and exposure to external factors.
