Enriching a cellulose hydrogel with a biologically active marine exopolysaccharide for cell-based cartilage engineering ArchiMer
Rederstorff, E.; Rethore, G.; Weiss, P.; Sourice, S.; Beck-cormier, S.; Mathieu, E.; Maillasson, M.; Jacques, Y.; Colliec-jouault, Sylvia; Fellah, B. H.; Guicheux, J.; Vinatier, C..
The development of biologically and mechanically competent hydrogels is a prerequisite in cartilage engineering. We recently demonstrated that a marine exopolysaccharide, GY785, stimulates the in vitro chondrogenesis of adipose stromal cells. In the present study, we thus hypothesized that enriching our silated hydroxypropyl methylcellulose hydrogel (Si-HPMC) with GY785 might offer new prospects in the development of scaffolds for cartilage regeneration. The interaction properties of GY785 with growth factors was tested by surface plasmon resonance (SPR). The biocompatibility of Si-HPMC/GY785 towards rabbit articular chondrocytes (RACs) and its ability to maintain and recover a chondrocytic phenotype were then evaluated in vitro by MTS assay, cell counting...
