Telomerase activity analysis. Telomerase activity is presented in the form of relative absorbance. human embryonic stem (hES) cell or induced pluripotent stem (iPS) cells were grown in Matrigel-coated feeder-free wells and harvested for analysis. The iPS cell clones (stem cells from exfoliated deciduous teeth (SHED) at passage 33; stem cells from apical papilla (SCAP) at 27; dental pulp stem cells (DPSCs) at 41) used for this assay were the same as those for karyotyping. Their non-transduced counterparts were all at passage 3. 293T cells were used as positive control; heated 293T cell extract was negative control (HI).
