Table 2.

The reproduction rate of Sca-1⁺ CSCs at 24 h, 48 h and 27 h after transfection by the MTT assay in blank, NC, miRNA-21 mimic, and miRNA-21 inhibitor groups.

Group	Reproduction rate (%)
	24 h	48 h	72h
Blank	100	100	100
NC	−6.79*	−7.99*	−8.75*
miR-21 mimic	17.67*	19.6*	35.10*
miR-21 inhibitor	−20.25*	−27.48*	−30.63*

MTT – methyl thiazolylte-trazolium; NC – negative control; CSCs – cardiac stem cells

^*Compared to blank group, P<0.05.
