The following is an edited excerpt.
A new study done by researchers at Stanford has shown some remarkable epigenetic differences between the stem cells of younger mice and older mice.
Scientists found that as stem cells age, they show higher levels of gene deactivating methylation across the board. However, what this ultimately has to do with the aging of an individual requires more studies. It’s possible that the higher levels of methylation could ultimately lead to more DNA damage, and thus a higher chance for the sorts of genetic abnormalities common in older individuals, like cancer.
