Telomerase activity and telomere length of primary or hTERT-stromal cells.
(A) Telomerase activity. Lane 1, primary stromal cells; lane 2, hTERT-stromal cells at PD = 10; lane 3, hTERT-stromal cells at PD = 60; lane 4, hTERT-stromal cells at PD = 100. (B) Telomere length. Lane 1, primary stromal cells; lane 2, hTERT-stromal cells at PD = 10; lane 3, hTERT-stromal cells at PD = 60; lane 4, hTERT-stromal cells at PD = 100.
