Figure 3. SA-b-Gal activity in MK/T-1 and parental cells

SA-b-Gal activity was not detected in passage 190 MK/T-1 cells (Left panels: MK/T-1) while the parental cells had already upregulated SA-b-Gal at high levels by passage 9 (Right panels: Parental). All preparations shown are representative fields and were incubated in identical SA-b-Gal staining solutions for equal lengths of time. Individual cells are arrowed in each panel.
