A Japanese study examined age-related biomarkers including telomere length, senescence markers, hematopoiesis, glycated hemoglobin, blood glucose, insulin sensitivity, and inflammatory cytokines across elderly, centenarian, semi-supercentenarian, and supercentenarian populations.

“Recent study has been published by this Japanese group where they looked at a variety of different biomarkers that are age-related. So, these scientists looked at telomere length markers of senescence. They looked at hematopoiesis. They looked at glycated hemoglobin, blood glucose levels, insulin sensitivity. They looked at inflammatory cytokines biomarkers of inflammation, biomarkers of all the inflammatory pathways. And they looked at it in three different populations of people: the elderly, which are about 85 to 90 years old; centenarians, which were 100 years old; and then, semi-supercentenarians, which are like 105; and then supercentenarians, which are 110 up to 115.”
