Morphology of human WJCs and expression of GFP in WJCs. a After initial culturing for 3 days, fibroblast-like cells migrated out from the enzyme-digested Wharton’s jelly tissues and adhered to the culture dish, and the fibroblastic colony formation could be observed. b After 3 days in culture, passage 3 Wharton’s jelly MSCs appeared to be mostly spindle-shaped or triangular. c Fluorescent imaging of WJCs infected with AAV2 expressing EGFP with multiplicity of infection (MOI) of 1 × 105 vector genome/cell. d Vector incorporation was 79.7 % at 5 days after AAV2-EGFP infection (bar = 50 μm). EGFP enhanced green fluorescent protein
