Three-dimensional cell culture material having sugar polymer containing cell recognition sugar chain
Amcite Research, Ltd., Kanagawa-ken, JP;
Abstract
A cell culture material comprising a sugar containing polymer in which at least one kind of sugar chain is bonded as a side chain via a spacer molecule is made into a three-dimensional shape whereupon a three-dimensional cell material is prepared. With regard to the sugar containing polymer, a sugar containing polymer having a carboxyl group such as alginic acid, hyaluronic acid, pectic acid or a derivative thereof is preferably used. Sugar chain having a specific recognition to a cell is bonded as a side chain and, therefore, when the cell is incubated using the cell culture material, it is possible to maintain and improve the proliferation, morphology and function of the cells and to retain the cell form in a form of near that in vivo due to a specific interaction between the cell and the sugar chain.
