Figure 7
Sequential passage experiments with primary and recombinant cells. (A) Left panel, Results of sequential passages of A634 derived primary, A634 derived K4DT, A634 derived K4DTā+āTERC and A634 derived K4D cells. Right panel, Results of sequential passages of A640 derived primary, A640 derived K4DT, A640 derived K4DTā+āTERC and A640 derived K4D cells. X indicates the termination of cell growth. (B) Left panel, senescence-associated Ī²-galactosidase staining of A634 derived K4DTā+āTERC cells at passage 36. Right panel, senescence-associated Ī²-galactosidase staining of A640 derived K4D cells at passage 38. Arrows indicates the positively stained cells.
