  • METHOD FOR ISOLATING AND EXTRACTING ADIPOSE-DERIVED STEM CELLS FROM ADIPOSE TISSUE AND CULTURING SAME WITHOUT USING COLLAGENASE, AND KIT FOR ISOLATING AND EXTRACTING ADIPOSE-DERIVED STEM CELLS
    Publication number: 20200407690
    Abstract: Adipose-derived stem cells are isolated and extracted from an adipose tissue without using collagenase. An adipose tissue is covered with a nonwoven fabric sheet having sufficient interfiber space and pressed by an appropriate force. Thus, the adipose tissue infiltrates among fibers of the nonwoven fabric and then comes into contact with fibers surrounding the same. By immersing the nonwoven fabric as such in a culture medium, a number of adipose-derived stem cells are allowed to crawl out from the adipose tissue and then adhered to the fiber surface.

  • Structure used for animal cells, method of separating animal cells, and method of adjusting elasticity of surface of structure used for animal cells
    Patent number: 10513683
    Abstract: A structure used for animal cells is provided which includes an elastic body layer having a flat surface on which animal cells are left. The elastic body layer has a surface whose elasticity is changed by partially supporting the elastic body layer from the rear side or by changing a thickness of the elastic body layer.

  • Substrate for controlling movement direction of animal cells, and cell identification method and cell separation method using the same
    Patent number: 9958429
    Abstract: The present invention provides a control substrate for controlling a movement direction of animal cells. The control substrate for controlling a movement direction of animal cells has a surface which includes a plurality of grooves, the grooves are formed from a bottom between opposing walls and the opposing walls forming the grooves wherein the walls include a plurality of columnar protrusions. Vertex parts of the columnar protrusion are formed to face between vertex parts of two columnar protrusions formed in the opposing wall and such vertex parts face the same direction.
