CFP and YFP, but Not GFP, Provide Stable Fluorescent Marking of Rat Hepatic Adult Stem Cells
Figure 2
Stable, long-term expression of CFP fluorescence in stably transfected
rat hepatic ASC clones. Three cell clones expanded from CFP-transfected
colonies, B1, B2, and B3 (as described in text), were propagated and serially
analyzed for CFP expression. At the indicated number of population doublings,
the percentage of fluorescence-expressing cells was determined by flow
cytometry for each specified clone. The
cells have been passaged for a maximum of 140 population doublings.
