Abstract:
The present inventions relates to beads as biocompatible material adapted for use within the human or animal body. Said beads arc highly useful for tissue engineering, in situ tissue regeneration, as well as for drug and/or cells delivery. In addition, said beads may support biotechnological applications such as cell carriers.

Claim (Index 10):
A crosslinked polysaccharide bead having a substantially spherical or ovoid shape obtained by\n a) preparing an alkaline aqueous solution comprising at least one polysaccharide and a cross linking agent; b) in the absence of surfactant dispersing said alkaline aqueous solution into an hydrophobic phase consisting of a vegetal oil, in order to obtain a water-in-oil (w/o) emulsion; and c) transforming the w/o emulsion into beads by placing said w/o emulsion at a temperature from about 4\u00b0 C. to about 80\u00b0 C. for a sufficient time to allow the cross-linking of said at least one polysaccharide; wherein said polysaccharide is selected from the group consisting of mixtures of dextran and pullulan and mixtures of dextran, pullulan and fucoidan, wherein said crosslinked polysaccharide bead is free of any organic solvent and surfactant, and wherein said crosslinked polysaccharide bead has a mean diameter of more than 10 \u03bcm.
