Cell viability staining of primary human primary PDL cells exposed to control (TCP), non-cross-linked HA (HA_ncl) and cross-linked HA (HA_cl) surfaces. For cell viability, Live-Dead staining was done with viable cell appearing in green and dead cells in red. The results from these experiments demonstrated that both HA_ncl and HA_cl are highly biocompatible at dilutions of 1:100 and 1:10 as well as pre-coated onto cell culture plastic
