In vitro activation induces telomerase in naive and memory tonsil B cells. (A) The results shown are representative of telomerase induction in naive and memory tonsil B cells with in vitro activation. Similar results were obtained in three independent experiments. (B) Relative levels of telomerase activity in naive and memory tonsil B cells induced by different stimulation conditions. The relative levels of telomerase activity were determined as described in the text and in the legend of Fig. 2.
