Patent
Q - Cells SE | Date: 2012-05-10

A method for picking up a substrate includes leading an electrostatic holder to the substrate, applying an electrical voltage having a first voltage value to the electrostatic holder in such a way that the substrate is accelerated in the direction of the electrostatic holder, and reducing the voltage applied to the electrostatic holder to a second voltage value, the absolute value of which is lower than the first voltage value.


A cell preparation containing mesenchymal stem cells whose immunosuppression ability is maintained is produced by means of a serum-free or low-serum culture. A method for producing a cell preparation containing mesenchymal stem cells, comprising the steps of: (A) proliferating mesenchymal stem cells in a serum-free medium A containing an FGF, a PDGF, a TGF-, an HGF, an EGF, at least one phospholipid, and at least one fatty acid; and (B) screening mesenchymal stem cells whose immunosuppression ability is maintained or improved, from the mesenchymal stem cells thus proliferated in the step (A).


Disclosed are: a culture medium containing a specific growth factor and at least one phospholipid; a composition for preparation of the culture medium; a kit; and a method. A technique can be provided which uses a serum-free or low-serum culture medium and has a promoting effect on the proliferation of an animal cell comparable to the promoting effect obtained by the culture in a serum-containing culture medium.
