Human blood retains DNA-marking patterns formed before birth

Each blood cell carried about 300,000 acquired DNA-marking changes before birth, including more than 3,000 in large segments that remained stable for decades.Each blood cell carried about 300,000 acquired DNA-marking changes before birth, including more than 3,000 in large segments that remained stable for decades.

Most DNA-mark differences in human colon cells traced to embryos

By around age 60, a colorectal cell lineage had about 1.2 million DNA-mark differences from a reference pattern; about 60% dated to early embryos.By around age 60, a colorectal cell lineage had about 1.2 million DNA-mark differences from a reference pattern; about 60% dated to early embryos.
