A substance introduction device introduces a substance into a cell by electroporation, and includes at least one substance introduction unit including an accommodation container that accommodates a cell suspension containing the cell and the substance and a pair of electrodes that applies a voltage to the cell suspension accommodated in the accommodation container; and a liquid delivery unit that delivers a liquid to the accommodation container. The accommodation container has a first and a second openings, and the liquid delivery unit fills the accommodation container with the cell suspension before voltage application through the first opening and to discharge the cell suspension after the voltage application from the accommodation container through the second opening, and to fill the accommodation container with a cleaning solution through the second opening and to discharge the cleaning solution from the accommodation container through the first opening.

An electroporation apparatus comprising an elongated hollow member in order to provide a uniform electric field during electroporation, wherein specifically, electroporation is carried out by applying electric pulses through a couple of electrodes from both end parts of the elongated hollow member, after the hollow member is charged with fluid specimen including cells and material which would be injected into the cells.

The development of the method of the invention enables the efficient and reproducible production of genetically modified GMP-grade human macrophages. The inventors have described the effects of the method described on cell viability and efficiency of introduction of genetic material into macrophages. Unlike previous methods of introducing genetic material into macrophages, excellent conditions are demonstrated which produce efficient transgene expression, without compromising cell viability. Critically, the method of the invention does not use virus to introduce genetic material, is efficacious on mature cells, are functional with in vitro assay and in vivo transfer in a liver disease model and complies with practices compatible with manufacture and delivery of these cells to patients.

The present disclosure relates to a method for producing cultured meat, the method including: forming a cell sheet by culturing cells usable for producing cultured meat; and culturing the cells in a form in which a nanofilm is formed on a surface of the cell sheet by coating the cell sheet. The present disclosure provides a method for producing cultured meat that implements excellent mechanical strength by protecting a cell layer from external stress and performing stable cell proliferation, and provides cultured meat implementing quality and taste that are improved compared to those of conventional cultured meat by reproducing tissue similar to muscle tissue of an actual animal.

The invention provides an automated system for producing induced pluripotent stem cells (iPSCs) from adult somatic cells. Further, the system is used for producing differentiated adult cells from stem cells.

The present invention relates to a composite membrane. The composite membrane includes: an elastic polymer substrate having a first surface processed by a surface modification; and a thermosensitive conductive layer formed on the first surface by performing a co-polymerization process, allowing an electrical current to pass through, and altering a hydrophilicity of a membrane surface in response to a change of a temperature.

Examples disclosed herein relate to single cell transfection with interchangeable reagent. The present disclosure relates generally to a device, method, and system for single cell transfection including a transfection chamber on a transfection chip. The example system may include a fluidic channel located on the transfection chip for guiding a cell towards the transfection chamber, the fluidic channel sized to allow no more than a single cell to arrive at the transfection chamber at a time. The example system may also include a reagent receiver located on the transfection chip guiding received reagent towards the transfection chamber and intersecting with the path of the fluidic channel.

Disclosed herein are cell processing systems, devices, and methods thereof. A system for cell processing may comprise a plurality of instruments each independently configured to perform one or more cell processing operations upon a cartridge, and a robot capable of moving the cartridge between each of the plurality of instruments.

Provided herein are methods of culturing organized skeletal muscle tissue from precursor muscle cells by cyclically stretching and relaxing said muscle cells on a support in vitro for a time sufficient to produce said organized skeletal muscle tissue, including reseeding said organized skeletal muscle tissue by contacting additional precursor muscle cells to said organized skeletal muscle tissue on said solid support, and then repeating said step of cyclically stretching and relaxing said muscle cells in said support in vitro for time sufficient to enhance the density (i.e., increased number of nuclei and/or number of multinucleated cells) of said organized skeletal muscle tissue on said support.

Provided is an electroporation device and a method for producing cells with an introduced foreign substance, with which, compared to a device that performs electroporation by causing a solution (droplet) containing a foreign substance and cells to reciprocate in oil, an operation to recover a sample after a reaction is simplified.

An electroporation device (1) includes a holding portion (2), a discharge generating portion (3), a conductive portion (4), and a power amount control portion (5). The holding portion (2) is configured to hold a solution containing a foreign substance and a cell. The discharge generating portion (3) includes a pair of electrodes disposed at a predetermined gap, and configured to generate an arc discharge between the pair of electrodes. The conductive portion (4) is configured to electrically connect the holding portion and the discharge generating portion, and to supply, to the holding portion, a pulsed electric current resulting from the arc discharge generated by the discharge generating portion.
