- a problem to be solved is that a method for culturing and growing adherent animal cells normally in a floating state and re-establishing the cultured and grown adherent animal cells in a desired place has not been established. .
- the cell release method according to the present invention comprises culturing in a cell culture solution in a state where the adherent animal cells are adhered to the surface of the carrier, and then the cell release solution containing ratatopherin and the cell culture.
- the serum concentration is 5 to 20% because the serum concentration is less than 5% or 20%. This is because if it exceeds, there is a disadvantage that the proliferation rate of the cells decreases.
- the concentration of ratatopherin was set to 10 to 500 M because the cell release effect was small when the concentration of ratatopherin was less than 10 M, and the cell release effect was saturated when the concentration exceeded 500 M.
- the components obtained by removing lactofrin from the cell free solution may be substantially the same as the components of the cell culture solution in that the released cells can be cultured as they are. I like it.
- the cell release solution according to the present invention is characterized in that it comprises a cell culture solution containing at least 1 to ratatopherin: LOmM.
- the concentration of ratatopherin in the culture solution was set to 1 to LOmM because it is easy to use if the ratatopherin concentration is within this range.

- the concentration of ratatopherin in the culture medium was set to 10 to 500 M. If the concentration of ratatopherin was less than 10 M, the effect of floating the cells was reduced, and the cells floated when the concentration exceeded 500 M. This is because the effect is saturated.
- the cell solution containing the adhering animal cells in the floating state and ratatopherin is placed in the planned fixing portion, and then the culture solution not containing ratatophorin is added to the fixed fixing portion.
- the concentration of ratatophosphorin in the cell solution reduced in concentration by a culture solution not containing ratatopherin is preferably less than 10 ⁇ . Below 10 cm, suspension cell colonization is a significant force.
- a cell solution containing adhering animal cells in a floating state is placed in a part to be fixed, and then the cell of the adhesive animal cell is put into the cell liquid in the part to be fixed.
- a cell colonization method in which a deadline substance that abolishes stray effects is added to fix the adherent animal cells to the area to be fixed, wherein the cell fluid is 5 to 20% serum and 10 to 500 ⁇ ⁇ ratatopherin. It is characterized by including.
- the cell fixing solution a culture solution containing glycosaminodarlican can be used.
- the concentration of glycosaminodarlican in the cell solution when the adherent animal cells in a floating state are fixed is preferably 10 to 500 gZml. This is because if the concentration of glycosaminoglycan is less than 10 ⁇ gZml, the effect of fixing floating cells is insufficient, and if it exceeds 500 gZml, the effect of fixing floating cells is saturated.
- the cell fixing solution according to the present invention contains glycosaminodarlican in the culture solution! It is characterized by this.

- the adherent animal cells refer to, for example, nerve cells, glial cells, epithelial cells, various undifferentiated cells (mesenchymal cells, stem cells, etc.), cancer cells and the like.
- the culture solution includes not only a nutrient containing cells to grow but also a simple one that retains cells such as physiological saline.
- cells that float and adhere to cells have a higher cell proliferation ability than cells that can be cultured normally in a suspended state. There is an effect that normal cells having no cell can be obtained rapidly and in large quantities.
- the cells can be cultured in a suspended state, there is an effect that the cultured cells can be easily transported and transported.
