A core-shell gel particle of the invention contains a crosslinked hyaluronic acid, has a higher equilibrium swelling capacity at the surface than at the center, the equilibrium swelling capacity showing a change curve with an inflection point from the center to the surface, and has a probe pushing force of 20 nN or less from the surface to a depth of 800 nm.

Core-shell crosslinked hyaluronic acid gel particles, production method for same, and medical material

Provided is an agent for preserving a biological component, comprising a hydrogel, the hydrogel comprising a crosslinked product formed from a compound having a plurality of hydroxyl groups and a modified hyaluronic acid having substituents capable of reacting with the hydroxyl groups to form a crosslinked structure.

Agent for preserving biological component

The present invention provides a crosslinked hyaluronic acid composition including self-crosslinking hyaluronic acid particles having an equilibrium swelling capacity of 3-fold to 10-fold, and an aqueous solvent, wherein a dry weight of the self-crosslinking hyaluronic acid particles based on the total volume of the crosslinked hyaluronic acid composition is 3 w/v % to 8 w/v %. The crosslinked hyaluronic acid composition of the invention uses self-crosslinking hyaluronic acid particles of which the equilibrium swelling capacity is within the above predetermined range. Accordingly, the viscosity does not sharply increase even if the concentration thereof is increased. Therefore, if the crosslinked hyaluronic acid composition is applied to an injection, it is possible to obtain a sufficient curative effect on knee osteoarthritis even with a small frequency of administration.

Crosslinked hyaluronic acid composition and self-crosslinking hyaluronic acid particles
