Abstract

PURPOSE: To obtain the polysaccharide-calcium phosphate which is useful for living body or supporting body for cultivating cell by forming the title substance from a gel formation agent selected from at least one kind of polysaccharide among carageenan, phaselerane, etc., and a specific solid calcium phosphate.
CONSTITUTION: The title substance is prepared from the gel formation agent constituted of at least one kind of polysaccharide selected among carageenan, phaselerane, low methoxypectin, and geranic rubber and solid calcium phosphate having a Ca/P ratio of 1.5-1.9. As such calcium phosphate, the compound containing hydroxy apatite or tricalcium phosphate as main constituents is preferable. Further, in order to accelerate gel formation, hydroxy apatite contained as main constituent, or calcium compound having the higher solubility than that of tricalcium phosphate, e.g. calcium phosphate containing calcium oxide as subconstituents can be used. Therefore, the polysaccharide-calcium phosphate complex gel which is useful for living body, supporting body for cultivating cell, and the like can be obtained.
