"Research indicates that the best estimate of your age is from markers in your cells."
As everyone is different and ages at a different pace, years or any other method might not be as effective in telling someone's age as it is biomarkers. A few examples of biomarkers are the interleukin 6, the transferrin receptor, the insulin-like growth factor, the albumin, the creatinine, and several others.

"The cells examined from the 2,400 people in this study were from blood."
All these biomarkers mentioned above can be found in the blood, in fact, much of what is considered to be a biomarker has to do with blood cells counting and receptors in them as well as biomolecules that are found in the blood. There are many other biomarkers that are measured through the blood such as the total cholesterol, the haemoglobin and white blood cell counts.

Answer from: Quest

layer 3 is younger than layer 6.

Answer from: Quest

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
