Twenty-four hour old cell cultures were treated with HA in the maintenance medium and then incubated for different times: 24 hours for VERO cells, 48 hours for MDCK and MARC 145 cells, 72 hours for PK15 cells and 6 days for JJHAN cells. Then, the MTT assay was performed. Cell viability was calculated as the percentage of optical density of the HA-treated cultures in comparison with that one of untreated controls (100% viability).
