Percentage of surface marker expression on cells expanded for 10 days on different nanofibre matrices and tissue culture polystyrene surface. Values were expressed as the mean ± s.d. (n = 3 independent experiments). Asterisk (*) denotes p < 0.05 when compared with TCPS control.

cells expanded on various substrate	CD34+(%)	CD133+(%)	CXCR4+ (%)	CD34+/CXCR4+ (%)
unexpanded cells	85.7 ± 3.3	97.4 ± 1.3
tissue culture polystyrene (TCPS)	7.8 ± 0.7	8.1 ± 0.8	38.0 ± 6.1	1.8 ± 2.0
EDA-grafted nanofibres (two-step grafting)	25.3 ± 6.6*	11.6 ± 2.1*	37.5 ± 4.5	3.9 ± 2.5
AEMA-grafted nanofibres (one-step grafting)	21.6 ± 4.1*	13.8 ± 2.5*	40.6 ± 7.2	8.0 ± 2.6*
