ELECTROPORATION, DEVELOPMENTALLY-ACTIVATED CELLS, PLURIPOTENT-LIKE CELLS, CELL REPROGRAMMING AND REGENERATIVE MEDICINE
The claimed invention is directed towards a novel combination cell electroporation/cell culturing apparatus which can be termed a cell culture dish suitable for in vitro electroporation, and towards a device suitable for in vivo electroporation—both useful in methods suitable for the generation of developmentally-activated, pluripotent, pluripotent-like, multipotent, and/or self-renewing cells which are capable of beginning to differentiate in culture into a variety of cell types and capable of further differentiation in vivo. The claimed invention is also directed towards the generation of desirable, differentiating somatic cell populations transplantable to animals or patients, genetic modification of endogenous and exogenous cells, and the treatment of patients suffering from diseases that may be ameliorated by these methods. This invention also provides methods for preventing, treating, or retarding disease, for example, immunodeficiency virus (e.g. HIV-1, HIV-2, SIV, FIV, etc.) infection.
SUBSTANCE INTRODUCTION DEVICE AND SUBSTANCE INTRODUCTION METHOD
A substance introduction device includes at least one turbulence grid that generates turbulence in a fluid containing a cell and a substance to be introduced into the cell, in which at least a part of the at least one turbulence grid is formed of a conductive material that applies charge to the cell in the fluid. A substance introduction method includes a stress/charge applying step of applying, while generating turbulence by flowing a fluid containing a cell and a substance to be introduced into the cell through at least one turbulence grid, charge to the cell in the fluid by a conductive material forming at least a part of the at least one turbulence grid.
ELECTROPORATION
An electroporation system may include a well plate, a dispenser and a dispenser-well positioning system. The well plate may include wells, each of the wells including an interior, a first electrode adjacent the interior and a second electrode adjacent the interior and spaced from the first electrode. The first electrode and the second electrode are to apply an electrostatic field across the well. The dispenser is to dispense a cell having a diameter into each of the wells. The dispenser-well positioning system is to align each well and the dispenser such that the dispenser dispenses the cell into each well at a location spaced from the first electrode and the second electrode by a distance of at least 5 times the diameter of the cell.
CULTURE APPARATUS AND CULTURE METHOD
A culture apparatus includes a fine water generating cartridge disposed in an air passage by which moisture is supplied into a culture space and that goes into a moisture absorption state in which moisture in air is adsorbed on conductive polymer films by reducing the temperature of a base material having the conductive polymer films, and goes into a moisture release state in which fine water with a particle size of 50 nanometers or less is released from the moisture adsorbed on the conductive polymer films by increasing the temperature of the base material; and a control part performing moisture absorption control bringing the fine water generating cartridge into the moisture absorption state, and moisture release control releasing the fine water by bringing the fine water generating cartridge into the moisture release state supplied into the culture space, by irradiating the subject with the fine water.
CONTINUOUS AUTOMATED PERFUSION CULTURE ANALYSIS SYSTEM (CAPCAS) AND APPLICATIONS OF SAME
A continuous automated perfusion culture analysis system (CAPCAS) comprises one or more fluidic systems configured to operate large numbers of biodevices in parallel. Each fluidic system comprises an input reservoir plate for receiving media; a biodevice plate comprising an array of biodevices fluidically coupled to the input reservoir plate, configured such that each biodevice has independent media delivery, fluid removal, stirring, and gas control, and each biodevice is capable of continuously receiving the media from the input reservoir plate; and an output plate fluidically coupled to the biodevice plate for real-time analysis and sampling. The operations of the CAPCAS are automated and computer-controlled wirelessly. The CAPCAS can also be used for abiotic and biotic chemical synthesis processes.
High density distributed three-dimensional electrode device
Disclosed herein is a high-density distributed three-dimensional electrode device and an associated electroporation method. The method includes applying an electric pulse of a first polarity to a first group of electrodes while simultaneously applying an electrical pulse of a second polarity to a remaining group of electrodes, and then applying an electric pulse of the first polarity on a second group of electrodes while simultaneously applying an electric pulse of the second polarity to the remaining groups of electrodes. The electrodes receiving the electric pulse of the first polarity being surrounded by the electrodes receiving the electric pulse of the second polarity, and the first polarity and the second polarity are opposite.
Cell treatment system
A cell treatment system includes an analysis unit to calculate the area or size of each of cell aggregates existing on the cell culture vessel based on an image; a display device to show the area or size of each of the cell aggregates on a display; a laser irradiator to emit laser toward the cell culture vessel so as to kill cells existing on the cell culture vessel; an input device to receive an operation input designating cells to be killed with irradiation of the laser or cells to survive without the irradiation of the laser among the cells existing on the cell culture vessel, or an operation input designating a position to be irradiated with the laser or a position not to be irradiated with the laser on the cell culture vessel; and a control unit to control a position irradiated with the laser.
METHOD AND DEVICE FOR CONTROLLING THE FILLING LEVEL IN A CHAMBER
The invention relates to a method and device for controlling a filling level of a suspension of cells, cell derivatives, organelles, sub-cellular particles and/or vesicles within at least one chamber of a device for applying an electric field to the suspension. In order to avoid overfilling of the chamber if multiple electroporation cycles are performed and to achieve exact filling in an environment of unpredictable chamber volume, the amount of suspension filled into the chamber is dynamically limited in the course of several electroporation cycles by determining at least one change of the electrical resistance at the outlet port. The resistance between at least one electrode and a grounding electrode is measured during the filling procedure of each cycle at several points in time. Once a change of resistance is detected, the termination routine is initiated and the filling procedure is finally terminated. Exact filling of the chamber is thus ensured during each electroporation cycle so that enhanced reproductive electroporation performance can be guaranteed.

The present disclosure provides automated modules and instruments for improved detection of nuclease genome editing of live cells. The disclosure provides improved modules—including high throughput modules—for screening cells that have been subjected to editing and identifying and selecting cells that have been properly edited.
AN ELECTROPORATION APPARATUS AND METHOD
An electroporation apparatus has an electroporation probe terminals for linking with electrodes. A foam is injected at the treatment site to displace blood rather than mixing with it, increasing the contact time of a higher concentration of active agent with the tissue and thus resulting in greater efficacy. With foam solutions, a lower concentration of agent can be used to obtain the same therapeutic effect as in their liquid counterpart, reducing the prevalence of side effects associated with higher concentrations. A foam solution compared to an equivalent liquid solution enables more efficient cell electroporation particularly where bipolar pulses have been employed by mitigating an increase in tissue conductivity as would normally be observed with a comparable liquid solution. A more efficient cell permeabilization would result in better results where electroporation is being delivered alone or as a tool to aid in the uptake of molecules into the cell.
