US 2018/0022789 A1 · GELATIN PARTICLES, METHOD FOR PRODUCING GELATIN PARTICLES, GELATIN-PARTICLECONTAINING CELLS, METHOD FOR PRODUCING GELATIN-PARTICLE-CONTAINING CELLS, AND CELLULAR STRUCTURE

Abstract

Gelatin particles include: gelatin that serves as a main component; and an auxiliary component carried on the gelatin, the gelatin particles being configured such that where the particle size of the gelatin particles is X, the ratio A/B of the average concentration A (mass %) of the auxiliary component contained in a surface part having a thickness of 0.01X from the surface of the gelatin particles based on the total mass of the gelatin particles to the average concentration B (mass %) of the auxiliary component contained in an inner part of the particles deeper than the surface part based on the total mass of the gelatin particles is less than 0.25.
