1. A method for treating a liver-related disease, comprising:

administering adipose tissue-derived multilineage progenitor cells to a subject,

wherein the adipose tissue-derived multilineage progenitor cells are a population of cells obtained by:

(a) removing erythrocytes from a population of adipose tissue-derived cells, thereby to form a population of preadipose tissue-derived multilineage progenitor cells;

(b) culturing the resultant population of the preadipose tissue-derived multilineage progenitor cells;

(c) removing cells other than the adipose tissue-derived multilineage progenitor cells using ethylenediaminetetraacetic acid (EDTA) and without using trypsin.

2. The method according to claim 1 , wherein adipose tissue-derived multilineage progenitor cells are administered via portal vein.

3. The method according to claim 1 , wherein the liver-related disease is non-inflammatory.

4. The method according to claim 3 , wherein the liver-related disease is hemophilia or familial hypercholesterolemia.
