摘要:
It is intended to provide a method of preparing a decellularized soft tissue whereby swelling after an ultrahigh pressure treatment can be inhibited, etc. The above-described method of preparing a decellularized soft tissue comprises the application step wherein an ultrahigh hydrostatic pressure is applied to an isolated soft tissue in a medium to thereby disrupt cells in the soft tissue, and the removal step wherein the disrupted cells are removed. As the medium, use is made of an aqueous solution containing a water-soluble polysaccharide such as dextran.

Disclosed is a polymer brush composite including a substrate, a solid layer disposed on the substrate and containing at least one of a metal or a metal oxide, and a plurality of polymer chains penetrating the solid layer in such a manner that one end of each of the polymer chains is disposed on the upper side of the substrate and the other end of each the polymer chains is exposed at a surface of the solid layer on an opposite side of the solid layer to the substrate. The polymer brush composite exhibits good adhesion between an organic polymer compound and an inorganic material and has the surface the organic polymer compound and the inorganic material uniformly coexist.

An apparatus and method for inoculating a biological substrate with cells include provision for rotating a container in which the substrate and a cell suspension are received about first and second axes of rotation. The apparatus comprises said container, first drive means for rotatably supporting the container about the first axis, and second drive means for rotatably supporting the first drive means about the second axis. The first and second axes of rotation do not lie in the same plane and extend in different directions so that the container revolves around the second axis while the container is rotating about the first axis. The inoculation method utilizes this apparatus.
摘要:
Methods and apparatus for controlling biological functions with mechanical vibration are provided. Stimulation is applied to cells of one of an organism, bacteria or virus by mechanical vibration. The biological function comprises biological functions relating to cell growth. The biological functions relating to cell growth may include at least one of cell cultivation, cell proliferation, cell fusion, and cell differentiation.
摘要:
A method of injecting cells into a biological tissue comprising thrusting injection needle (200) under microvibration into tissue (5) secured by suction to tissue suction means (210) and effecting injection of a cell suspension into the tissue through the needle. There is also provided an apparatus for cell injection into the biological tissue.
摘要:
Provided are: a method for preparing a decellularized tissue product in which decellularized tissue can be filled with liquid while changes in the structure of support tissue constituting the decellularized tissue are inhibited; and a graft provided with a decellularized tissue product. The method for preparing a decellularized tissue product includes a reduced-pressure step for bringing an animal-derived decellularized tissue material and a liquid into contact under reduced-pressure conditions, and/or a pressurized step for bringing same into contact under pressurized conditions. The graft is provided with a decellularized tissue product prepared by the method of preparation.
