Fig. 2.

Morphology and confluency of parental ST14A (a, b), N548mu (8–2 clone) (c, d), and N548wt (7–12 clone) (e, f) cells in regular passaging conditions (i.e., at 33°C in serum; a, c, e) and after exposure to serum-deprived medium at 39°C for 48 hr (b, d, f). N548wt evokes increased cell survival, whereas N548mu leads to higher cell death in the cultures with respect to parental ST14A cells.
