A tissue processing system for dissociation of and release of cellular components from adipose tissue to prepare stromal vascular fraction includes a portable tissue processing unit for containing biological material including adipose tissue during enzymatic digestion processing and a digestion drive unit configured to receive the tissue processing unit for rotational processing of the tissue processing unit about an axis of rotation. The unit has an upright orientation and a reclined orientation in which the axis of rotation is at a reclined angle to horizontal relative to the upright orientation. The digestion drive unit is configured to receive and drive rotation of the tissue processing unit in the reclined orientation. Methods for processing biological material including adipose tissue include enzymatically digesting adipose tissue with rotation of a tissue processing unit around an axis of rotation in a reclined orientation.

Disclosed is a device (100, 200) for the disaggregation of tissue samples into individual cells or cell clumps in a closed flexible tissue sample bag (10); the device including two or more resilient feet (134/136, 234/236) which tread sequentially a tissue sample bag receiving area (148,248). Also disclosed is a heat transfer plate (150, 250) for transferring heat energy to or from the area (148,248), the plate having one plate surface (151,251) adjacent the area (148,248) and an opposing surface (152,252) exposed to external thermal influence which faces away from the area (148,248). Further disclosed is a tissue sample receiving bag (10) comprising one or more flexible plastics cavity (12) formed from two layers of the plastics sealed around their edges to form a generally rectilinear periphery with the cavity or cavities (12) within the periphery, and at one side of the periphery is formed one or more sealable access ports (16). One part of the bag is left unsealed to provide a tissue sample receiving opening.

A system and method for harvesting autologous tissue, mincing it into fragments that are visible and measureable when filtered, and delivering a portion of the tissue back into the patient without the need to directly touch the tissue. During the same surgical procedure, the tissue can be mixed with a biocompatible agent before introduction into the repair site.

A cell clump dispersing device for dispersing cell clumps is provided, including a dispersion structure module that includes at least one structure for providing fluid flow shear force. Each structure for providing liquid flow shear force includes an inlet for cell clumps to be dispersed to enter the structure, and at least one outlet for dispersed cell clumps to flow out of the structure. A diameter of the outlet is smaller than that of the inlet, and an end of at least one of the structure is capable of being connected to an end of another of the structure.

The present invention provides a device for adipose tissue processing, microfragmentation and facilitation of mechanical separation of adipose derived stem cells (“ADSCs”), methods of using the device to generate a stromal vascular fraction (“SVF”) and methods of the SVF.

Provided herein are filter cake-based systems and methods for cultivating cells and cell biomass therefrom. Provided herein is a system for cultivating cells and cell biomass comprising a filter chamber comprising at least one inlet and at least one outlet, at least one filter support located within the filter chamber, and a filter cake located on the filter support, wherein the filter cake comprises at least one filter aid and a plurality of cells. Provided herein is a method for optimizing the cultivation of cells and cell biomass, comprising providing a filter support, adding at least one filter aid to the filter support, adding a plurality of cells to the filter aid, wherein the cells and the filter aid together comprise a filter cake, growing the cells into a cell biomass in the filter cake, wherein the filter cake is at least partially compressible.

Devices and methods for the efficient disaggregation of tissue samples, separating the tissue into individual intact cells or small aggregates of cells for analysis. A device may include a chamber to receive fluid and a tissue specimen containing more than one cell to be disaggregated. The chamber may include an opening and an agitator in fluid contact with the fluid and the tissue specimen. The agitator may include a micromotor which provides rotational motion to a shaft and an impeller fixed to the shaft such that the impeller and the shaft rotate together upon provision of the rotational motion by the micromotor. The device may include an electrical energy source electrically coupled to the micromotor to rotate the impeller sufficient to disaggregate the one or more individual cells from the tissue specimen and in a manner which does not lyse the one or more individual cells.

The invention relates to a method and a biogas plant for producing biogas, preferably from rice straw, wherein a substrate is fermented in two reactors (1, 2) in a circulating manner, so that a methane production from cellulose-and/or lignocellulose-containing substrate can be improved.

The present invention provides a stem cell manufacturing system comprising: a pre-transfer cell solution sending channel 20 through which a solution containing cells flows; an inducer solution sending mechanism 21 which sends a pluripotency inducer into the pre-transfer cell solution sending channel 20; an inducer transfer apparatus 30 which is connected to the pre-transfer cell solution sending channel 20 and transfers the pluripotency inducer into the cells to produce cells harboring the inducer; a cell cluster production apparatus 40 which cultures the cells harboring the inducer to produce a plurality of cell clusters consisting of stem cells; and a packaging apparatus 100 which sequentially packages the plurality of cell clusters.

A valve assembly having a conical valve needle axially displaceable in a bore of a valve body wherein a portion of the larger diameter of the valve needle seats downstream at an annular ring when the valve is closed. There is an open area between one end of the valve body to the annular ring even at closure and nozzles for the input of a liquid. The inner wall of the valve body comprises at least one opening for the entry of a liquid under pressure following output of a slurry or liquid from a tube or pipe. The valve assembly is particularly useful in maintaining a semi-continuous or continuous pressurized flow of biomass from an extruder.
