Abstract

Background and aim: Cell encapsulation using biodegradable material has promising results for tissue engineering. Since pressure is an effective factor on stem cell behaviour and various concentrations of alginate create different pressures on the cells, therefore our goal was to evaluate the mechanical effect of 1/2% (w/v) and 1/8% (w/v) alginate containing high guluronic acid on viability and osteogenic capacity of HUCWJ cells.

Methods: Cell viability was evaluated by MTT assay after 1, 7 and 14 days. Alkaline phosphatase activity was evaluated by alkaline phosphatase assay kit after 14 and 21 days. Alizarin red S staining was performed for calcium deposition among histological section.

Results: MTT assay showed significant difference in the mean of viability rates between groups in day 14 (p < 0.05). Alizarin red S staining was higher in the group 1.8%. In addition, there was statistically significant higher ALP activity in the group 1.8% compared to the group 1.2%.
