Abstract: [Problems] To provide a novel use of multipotential stem cells originating in a fat tissue. [Means for Solving Problems] It is intended to provide a cell preparation which contains multipotential stem cells originating in a fat tissue and is usable for an ischemic disease, impairment of renal function, wound, urinary incontinence or osteoporosis. As the multipotential stem cells originating in a fat tissue, use is made of cells which proliferate in the case of centrifuging cells separated from a fat tissue and culturing the thus sedimented cells (an SVF fraction) under low-serum conditions. In an embodiment, a cell preparation containing the SVF fraction is provided.
