Figure 7. p16INK4a and
Bmi1 staining of three biopsies from each age group, shown as
the number of positive cells counted in a total 10 visual fields
for each sample. The average number of p16INK4a
positive cells per field was less than 5 in donors younger than
30 years of age, 10 in donors older than 30 of years and younger
than 50 years of age, and 30 in donors older than 50 years of
age (A). The number of Bmi1 positive cells was determined
in the same way. The average number of Bmi1-positive cells per
field was 50 in donors younger than 30 years of age, 30 in
donors older than 30 of years and younger than 50 years of age,
and 20 in donors older than 50 years of age (B).
