発明の名称 (英語) METHOD FOR EVALUATING HYDROGEL NEW
発明の概要(英語) Provided is a method for evaluating a hydrogel, the method including: a first measurement step for culturing adhesive cells on a hydrogel, staining living cells using a stain which exhibits color in a living cell, and measuring the number of living cells by microscopy; a second measurement step for cleaning the hydrogel after the first measurement step and measuring the number of living cells by microscopy; and an adhesion evaluation step for evaluating adhesion of cells to the hydrogel on the basis of the measurement result of the first measurement step and the measurement result of the second measurement step.
従来技術、競合技術の概要(英語) BACKGROUND ART
In recent years, three-dimensional network structure having a hydrogel polymer, and medical attention as materials. Hydrogels, the three-dimensional network structure held by a large amount of water.
As the hydrogel, pullulan, dextran, collagen, alginate, polyvinyl alcohol derived from a variety of the hydrogel are known, their mechanical strength, moisture-retaining property, the cell adhesion, such as biocompatible applications in accordance with the characteristics. For example, a cell adhesion of the hydrogel is high, the field of regenerative medicine as a scaffold of the cells can be used. On the other hand, the cell adhesion of the hydrogel, containing a therapeutic agent and the like can be used as a wound dressing.
For example, to Patent Document 1, tissue repair, a cell suitable for use in tissue regeneration can be used as a scaffold of the crosslinked dextran and pullulan mixture of the hydrogel are disclosed.
