Expression of markers of differentiated neural cells and activated caspase 3 in EBs and oligospheres

Cell type	CM1, %	NeuN, %	Nestin, %	GFAP, %	O4, %	O1, %
EB	6  ± 4	6  ± 2	89  ± 2	13  ± 1	38  ± 3	35  ± 5
Oligosphere	10  ± 5	27  ± 4	9  ± 4	6  ± 2	51  ± 7	54  ± 9

Data are given as cell-type percent as indicated by immunoreactivity to phenotypic markers in EBs and oligospheres (mean ± SEM, n = 5 for each).
