Figure 1. Clonogenic potential of antisense p16INK4a transduced cells. A) CFE performed at selected cell passages indicated by numbers of cell doublings. B) CFE values of keratinocytes transduced with antisense p16INK4a (red bars) or with empty vector (blue bars) were plotted against cell passages. C) Aborted colony values (% of paraclones) of keratinocytes transduced with antisense p16INK4a (red line) or with empty vector (blue line) were plotted against cell passages.
