Adoptive immune cells obtained by a method including (a) obtaining mammalian antigen-presenting associated cells; (b) culturing the resulting cells from step (a) in a culture liquid contained in a culture vessel coated with a sugar chain-containing polymer; and (c) detaching the cells from step (b) by shaking the culture vessel without treating the cells with an enzyme and without using a cell detaching tool. A method for treating a malignant tumor, type I diabetes, an atopic allergic disease or an infection, by administering the adoptive immune cells to a patient. A pharmaceutical composition for treating a malignant tumor, type I diabetes, an atopic allergic disease or an infection, including the adoptive immune cells and a pharmaceutically acceptable carrier.

Adoptive immune cells for tumor vaccines

The present invention provides a method for preparing adoptive immune cells comprising the following steps of a) obtaining mammalian antigen-presenting associated cells; b) culturing the resulting cells in a culture vessel coated with a sugar chain-containing polymer; and c) detaching the cells by shaking the culture vessel without treating the cells with enzyme and without using a cell detaching tool; adoptive immune cells obtained by this preparing method; a culture vessel coated with a sugar chain-containing polymer for use in this preparation method; a kit for preparing an adoptive immune cell vaccine; and a method and a medicine for treating a malignant tumor, type I diabetes, atopic allergic diseases or infections using the adoptive immune cells.

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.
