Sorting on basis of size within the SP fraction of embryonic-derived neurosphere cells

Size of cellsa	Relative percentage within SP	Stem cell frequency in SP	Resort profileb
Small (<10 μm diameter)	41 ± 8%	5.5%	Small-36 ± 16%
			Large-19 ± 9%
Large (>12 μm diameter)	23 ± 6%	9.7%	Small-17 ± 6%
			Large-26 ± 14%

^a The cell diameters were based on the profile obtained using a standard 3 μm bead.

^b The originally isolated small and large SP fractions were resorted. The resort profiles were similar to the large and small adult-derived SP fractions.
