eGFP expression increased after 5-Aza-2′-Deoxycytidine treatment.

<p>A) Bright field (upper row) and fluorescent (bottom row) images of D1 sorted corrected cells at different experimental time (scale bar: 150 µm). B) eGFP expression, analyzed by Real Time PCR, after 24 h and 48 h of treatment with 0.5 µM 5-Aza-2′-Deoxycytidine respect to untreated (0 h) (*p = 0.002); untreated cells, at 24 h and 48 h, usually showed a decreasing relative eGFP expression (data not shown).
