Quantitative comparison of the CFP-fluorescent cell fractions of cultures under undifferentiated and differentiated conditions. Flow cytometry quantification of the R2 region of flow histograms (see, e.g., in Figure 5) for three fluorescent cell clones (same as Figure 2). Data are the average % fluorescent cells at 24 weeks in cultures ± standard deviation (SD). Cells were analyzed under normal culture conditions (undifferentiated) and under conditions that increase differentiated progeny (differentiation), as described in the text.

	% CFP fluorescence (mean ± SD; n = 2) condition
Strain	Undifferentiated	Differentiated
B1	94 ± 0.02	94 ± 0.88
B2	33 ± 1.6	28 ± 0.87
B3	87 ± 0.32	79 ± 2.3
