Abstract

An object of the present invention is to provide novel mesenchymal stem cells demonstrating superior therapeutic effects against various diseases, a novel pharmaceutical composition containing these mesenchymal stem cells, and a method for preparing the same. The present invention relates to ROR1-positive mesenchymal stem cells. The ROR1-positive mesenchymal stem cells are preferably positive for CD29, CD73, CD90, CD105 and CD166 and are derived from umbilical cord or adipose tissue.

Claims (4)

1. A method for treating fibrosis, comprising administering ROR1-positive mesenchymal stem cells derived from umbilical cord tissue and/or a supernatant thereof proliferated in formulated medium,

wherein the RORI-positive mesenchymal stem cells are positive for CD29, CD73, CD90, CD I 05 and CD 166, and

wherein the formulated medium comprises at least two types of components selected from the group consisting of PTEN inhibitors, p53 inhibitors, p38 inhibitors, Wnt signaling activators and ROCK inhibitors.

2. The method for treating fibrosis of claim 1 , wherein the formulated medium comprises a PTEN inhibitor in a concentration ranging from 10 nM to 10 μM, a p53 inhibitor in a concentration ranging from 100 nM to 1 mM, a p38 inhibitor in a concentration ranging from 1 nM to 1 μM, a Wnt signaling activator in a concentration ranging from 1 μM to 10 mM and a ROCK inhibitor in a concentration ranging from 1 nM to 10 μM.
