Fig 4. Changes of the telomerase activity and the telomere length with prolonged culture.

Fig 4

(A) Relative telomerase activity in aged and young MDPSCs, and aged and young DPSCs at the 8th, 12th and 20th passages. *p<0.05. Data are expressed as the means ± SD of 3 determinations. The experiments were repeated four times (4 lots), and one representative experiment is presented. (B) Southern blot analysis of telomeres in aged and young MDPSCs, and aged and young DPSCs at the 8th, 12th and 20th passages. Molecular sizes (kbp) are indicated on the left. The experiments were repeated four times (4 lots), and one representative experiment is presented.
