  • Method for preparing stem cells from fat tissue
    Patent number: 9631176
    Abstract: The present invention provides a method for preparing homogeneous stem cells and/or precursor cells in a large amount, in a simple and efficient manner, from human (in particular, the subject per se). The present invention further provides a method for preparing tissue implant or graft in a large amount by the use of the stem cells and/or precursor cells of the present invention. The present inventors have unexpectedly discovered that an aspirate from liposuction contains a large number of stem cells and have established a method for preparing stem cells from such an aspirate from liposuction, and thereby achieved the above-mentioned object.

  • Cell differentiation of adipose-derived precursor cells
    Patent number: 9074190
    Abstract: The present invention provides a simple method for controlled differentiation of adipose-derived precursor cells. A method is provided for preparing a differentiated cell. The method comprises A) obtaining a mixture by mixing a) an adipose-derived precursor cell and b) a differentiated cell corresponding to a desired site; and B) culturing the mixture under sufficient conditions which allow the adipose-derived precursor cell to differentiate. The present invention also provides a composition for cell implantation comprising a) an adipose-derived precursor cell and b) a differentiated cell corresponding to a desired site.
