Age-linked DNA tags varied between individual mouse cells
An analysis of 1,132 mouse white blood cells across four ages linked faster cell division to greater gains in chemical DNA tags.An analysis of 1,132 mouse white blood cells across four ages linked faster cell division to greater gains in chemical DNA tags.

Who was studiedMouse white blood cells
What changedDNA tagging varied widely among mouse white blood cells; a subset had much higher levels, especially in older mice
The catchDNA methylation served as a stand-in measure of cellular aging
