Abstract

The purpose of the present invention is to provide the following: novel mesenchymal stem cells having an excellent therapeutic effect on various diseases, particularly diseases associated with fibrosis; and a pharmaceutical composition containing such mesenchymal stem cells. The present invention is a therapeutic agent for fibrosis that contains ROR1-positive mesenchymal stem cells and / or a culture supernatant thereof and that is for preventing or treating a disease associated with fibrosis. The mesenchymal stem cells are CD29-, CD73-, CD90-, CD105-, and CD166-positive and are preferably derived from the umbilical cord or fat. In addition, the abovementioned disease associated with fibrosis is preferably a liver disease, a lung disease, a kidney disease, or a heart disease.

Description

technical field

[0001] The present invention relates to a pharmaceutical composition for preventing or treating diseases accompanied by fibrosis containing ROR1-positive mesenchymal stem cells, a preparation method thereof, and prevention of diseases accompanied by fibrosis using ROR1-positive mesenchymal stem cells or disposal method. Background technique

[0002] In recent years, drug development and regenerative medical research using cells or tissues of living organisms are advancing and attracting attention. Among them, ES cells and iPS cells are being rapidly researched as organ regeneration technology or drug discovery and screening tools. On the other hand, cell therapy that isolates and uses somatic stem cells (mesenchymal stem cells) from bone marrow, adipose tissue, umbilical cord, etc., uses adult stem cells in regenerative medicine to repair tissues damaged by diseases, etc. Since it is inherently functional, it has attracted attention and been researched as a...

[0107] [Preparation of ROR1-positive mesenchymal stem cells]

[0108] The method for preparing ROR1-positive mesenchymal stem cells is not particularly limited, and can be prepared, for example, as follows. That is, mesenchymal stem cells are isolated from umbilical cord, adipose tissue, bone marrow and other tissues according to methods known to those skilled in the art and cultured, and ROR1 is isolated by using an anti-ROR1 antibody that specifically binds to ROR1 through a cell sorter, magnetic beads, etc. Positive cells can thus be obtained. In addition, ROR1-positive mesenchymal stem cells can also be obtained by inducing the expression of ROR1 in mesenchymal stem cells by culturing using a medium described later. In the cell cluster obtained by this induction, preferably 70% or more of the cell cluster are ROR1-positive, more preferably 80% or more are ROR1-positive, still more preferably 90% or more are ROR1-positive, and particularly preferably substantially uniform ...
