Production of cellular substance

Abstract

Abstract PURPOSE:To obtain the titled cellular substance, having high safety, excellent biocompatibility, capable of regulating pores and useful for medical applications, by dissolving a copolymer of lactic acid and glycolic acid in an organic solvent, adding a specific filling substance, solidifying the solution and removing the organic solvent and filling substance. CONSTITUTION:The aimed cellular substance obtained by dissolving a polymer of lactic acid or copolymer thereof with glycolic acid in an organic solvent (e.g. dioxane), adding a filling substance, substantially inert to the above- mentioned solvent and soluble in water thereto, solidifying the solution, removing the above-mentioned solvent, adding water thereto and removing the afore- mentioned filling substance. Furthermore, e.g. sucrose, is preferably used as the filling substance.
