MTT test showed the cells cultured on heparinized, non-heparinized gels and culture dishes were viable and the various culture conditions had no significant effect on the number of viable cells. The cells also could proliferate in all conditions. However, in long term, the proliferation rate in conventional culture condition was higher than on the gels. * Significant difference with control cultured for 14 days (p < 0.05); ¥ Significant difference with control cultured for 7 days (p < 0.05); δ Significant difference with control cultured for 14 days (p < 0.05); £ Significant difference with cells cultured on heparinized gels for 14 days (p < 0.05)
