Reverse transcriptase-polymerase chain reaction (RT-PCR) was performed on cells transfected with pGRN145 Endogenous hTRT mRNA was detected with the primer set RA58 (5′-GGCTGAAGTGTCA-CAG-3′) and hTRT3′UTR (5′-GGCTGCTGGTGTCT-GCTCTCGGCC-3′). Exogenous hTRT mRNA was detected with the primer set RA58 and RA55 (5′-TCCGCACGTGAGAAT-3′). RT-PCR showed that the hTRT mRNA derived from the transfected cDNA, but not the endogenous hTRT mRNA, was present in telomerase-positive RPE (n = 4) and BJ (n = 3) clones (34). Ribonuclease protection assays were performed on BJ cells transfected with pZeoSV-hTRT and on H1299 cells (NCl-H1299, American Type Culture Collection). The probe corresponded to hTRT sequences spanning amino acids 541 to 647. The abundance of the catalytic subunit was comparable to that in H1299 cells (34). 21. DNA isolation and TRF analyses for the RPE and BJ clones were performed essentially as described (7), except that in some cases the DNA was resolved on 0.6% agarose gels and electroblotted to nylon membranes (78), and for mean TRF calculations, the average of the weighted and unweighted means was used [M. Levy, R. C. Allsopp, A. B. Futcher, C. W. Greider, C. B. Harley, J. Mol. Biol. 225, 951 (1992)].

Senescence is defined as less than one PD in 2 weeks; near-senescence is defined as less than one PD per week. Young BJ and RPE cells typically double in 1 to 2 days.
