A method for producing cell aggregates includes culturing cells while suspending the cells in a liquid culture medium comprising a lysophospholipid. A composition includes a lysophospholipid, wherein the composition is a liquid culture medium or a composition added to a liquid culture medium.

Herein is reported a method for co-cultivating one or more B-cells comprising the step of incubating the one or more B-cells with EL4-B5 cells, whereby the EL4-B5 cells have been obtained/are from a cultivation of EL4-B5 cells that has a cell density of from 600,000 cells/ml up to 1,500,000 cells/ml.

A method, apparatus, and system are provided for the printing and maturation of living tissue in an Earth-referenced reduced gravity environment such as that found on a spacecraft or on other celestial bodies. The printing may be three-dimensional structures. The printed structures may be manufactured from low viscosity biomaterials.

Provided is a means for appropriately controlling the size of cell aggregates without relying on mechanical/physical means. The present invention relates to a cell aggregation suppressor for use in suspension culture of cells, comprising an agonist of thrombin receptor. The present invention also relates to a method for producing cell aggregates, comprising a step of culturing cells in suspension in a culture medium comprising an agonist of thrombin receptor.

One aspect of the invention provides an apparatus for isolating one or more subcellular components including a cell disruption reservoir that generates at least one of a phase change, a thermal change, a physical contact force, an ultrasonic frequency, an osmotic change, a pressure change, a photothermal pulse, a magnetic field, an electromagnetic field, an electric field, and an electrical pulse through the reservoir and a separation instrument configured to specifically isolate the subcellular components based on one or more parameters selected from at least one of density, charge/pH, dielectric polarization, magnetic attraction, spectral dispersion, spectral refraction, spectral diffraction, hydrophobicity, hydrophilicity, structure (presence or absence of a structural feature), function (migration), affinity or binding, and pressure.

Herein is reported a method for co-cultivating one or more B-cells comprising the step of incubating the one or more B-cells with EL4-B5 cells, whereby the EL4-B5 cells have been obtained/are from a cultivation of EL4-B5 cells that has a cell density of from 600,000 cells/ml up to 1,500,000 cells/ml.

This invention relates to methods and compositions for detecting, identifying and treating glaucoma diseases. More particularly, this invention discloses compositions and methods for affecting intraocular pressure and increasing ocular outflows in glaucoma. Compositions and methods provided include purified and synthesized extracellular vesicle complexes from glaucoma ocular humor for use in methods and devices for detecting, characterizing and treating glaucoma diseases along with active agents. The presence of extracellular vesicle complexes in glaucoma can also be used as a biomarker.

Herein is reported a method for co-cultivating one or more B-cells comprising the step of incubating the one or more B-cells with EL4-B5 cells, whereby the EL4-B5 cells have been obtained/are from a cultivation of EL4-B5 cells that has a cell density of from 600,000 cells/ml up to 1,500,000 cells/ml.

Disclosed are liquids and methods for manipulating the localization and/or buoyancy of a population of particles, or one or more subpopulation thereof, within a volume of a liquid. The specific density of the liquids may be adjusted using specific gravity-modifying means depending on the application and/or on the average density of a population of particles, or one or more subpopulations thereof, within the liquid. For example, density-adjusted liquids may be used to bias a population of particles, or one or more subpopulations of particles, upward or downward within a volume of the liquid. As another example, density-adjusted liquids may be used to maintain the distribution of a population of neutrally buoyant particles, or one or more subpopulation thereof, within a volume of such liquid.

In order to develop tools and methods useful in a variety of applications, including the research and development of medical treatments which involve the modification of collagen protein and use of the same, the present invention provides a modified collagen protein expressed in a transformed cell and capable of forming collagen fibers outside of said cell, wherein the transformation is performed by introducing, into the cell, into the cell, polynucleotides coding the modified collagen protein.
