Abstract: A cultivation apparatus and a cultivation method of a culture such as a cell or tissue. Provided are an incubator unit for accommodating a culture and a lever that penetrates through the incubator unit and can move in circular arc around a fulcrum as a center, the fulcrum being set at a wall of the incubator unit or in the vicinity thereof, then displacement is imparted to the culture by operating the lever. Bending force can be acted on the culture (cell construct) such as a cell or tissue, so that without any increase or decrease of a culture fluid in the incubator unit, namely, without any increase or decrease of pressure to the culture fluid, displacement required for cultivation can be imparted to the culture in the incubator unit. By curving, continuous compression and extension are generated in a direction of thickness from a concave portion to a convex portion of the curving.

Abstract: A method for cultivating a culture of a cell, tissue, etc. There is provided a method of cultivating a culture including a cell or tissue (cell construct), imparting bending motion to the culture. By virtue of applying bending force to a culture of a cell, tissue, etc. (cell construct) to thereby curve the culture, continuous compression and extension in a direction of thickness from a concave portion toward a convex portion thereof are induced. The physical stimulation and deformation not attained by conventional pressurization, shear and tension, then can be loaded on the culture to thereby realize the culture appropriate for restoration of tissue at a region accompanied by bending.

Abstract: When a gas containing an amount of water vapor equivalent to that contained in the gas at the desired temperature Td and the desired relative humidity Hd is assumed, and the temperature of the gas when its relative humidity is 100% is defined as an intermediate target temperature Tc, Tc can be calculated from Td and Hd. The gas is mixed with water vapor to increase the temperature of the gas to the intermediate target temperature Tc while increasing the relative humidity of the gas to 100%. The gas heated to the intermediate target temperature Tc is heated to the desired temperature Td while maintaining the amount of water vapor contained therein so as to regulate the relative humidity of the gas to the desired relative humidity Hd. Gas maintained at the desired temperature and the desired humidity can thus be stably supplied.

Abstract: A culture chamber which cultivates a culture object by using a culture liquid has a culture space part which houses the culture object together with the culture liquid, an introducing part (an introducing port) which introduces the culture liquid into the culture space part, a discharging part (a discharging port) which discharges the culture liquid from the culture space part, and a flow arrangement part (a vertical wall, a small space part). The flow arrangement part is formed in a side of the introducing part of the culture space part, and causes a liquid flow, which reaches to the discharging part, to the culture liquid introduced into the culture space part from the introducing part by diffusing from inner wall surfaces of the culture space part toward a direction which intersects a virtual line connecting the introducing part and the discharging part.

Abstract: A cell/tissue culture apparatus for applying a desired tensile stress to a material to be cultivated such as a cell or tissue as a physical stimulation, thereby enhancing acceleration of culture of the material to be cultivated. The cell/tissue culture apparatus comprises a chamber (a culture chamber 8) for circulating a culture fluid (24), a material to be cultivated (a matrix 32) that is placed and cultivated in the chamber, stress generation means (an electromagnetic stretcher 38, an actuator 56) for causing a tensile stress to act on the material to be cultivated from an outside of the chamber, and control means (controllers 50, 60) for causing the tensile stress generated by the stress generation means to intermit as well as undergo gradual increase or gradual decrease. The material to be cultivated can be caused to undergo expansion or contraction by applying and relieving the tensile stress, thereby applying a physical stimulation necessary for the proliferation to the material to be cultivated.
