Figure 1. Screening fibroblast cell lines for young and aged phenotypes.

Figure 1

Expression of p16, p21, senescence associated β-gal and measures of cell area were performed. Results for each cell line are presented followed in parentheses by the relative rank (from highest to lowest) of the cell line in relation to the other cell lines. The last column is the average rank score for all four measurements. Three fibroblast cell lines with the highest average ranking were from aged donors (AG04383, AG04387, AG04064) and the three with the lowest ranking were from young donors (AG11747, AG11242, AG5415).
