Figure 3 (IMAGE) Impact Journals LLC Caption Morphological changes induced by long-term OSKM gene action in human umbilical cord perivascular cells (HUCPVC). (A) HUCPVC incubated for 7 days with an adenovector expressing a polyscistron harboring OSKM and GFP genes. Phase contrast microscopy; (B) The same field observed under fluorescence microscopy. (C) HUCPVC incubated for 85 days with the above OSKM-GFP adenovector. Phase contrast microscopy; (D) The same field as in C observed under fluorescence microscopy. Inset (E) Control intact HUCPVC on Experimental day 7. Obj X 4 in all panels. (Goya et al., unpublished results). Credit Correspondence to: Rodolfo G.
