The invention pertains to the field of adaptive cell immunotherapy. It aims at reducing the occurrence of translocations and cell deaths when several specific endonuclease reagents are used altogether to genetically modify primary immune cells at different genetic loci. The method of the invention allows to yield safer immune primary cells harboring several genetic modifications, such as triple or quadruple gene inactivated cells, from populations or sub-populations of cells originating from a single donor or patient, for their subsequent use in therapeutic treatments.

Culturing of organized 3D networks of neuronal cells is provided. Individual neuronal cells are encapsulated in gel beads. The gel beads are self-assembled into ordered structures in a bioreactor. Subsequent culturing of the cells in the bioreactor leads to the formation of an organized 3D network of the neuronal cells. Such structures have many applications, especially for as says of neuronal network function and/or structure.

A method and device for transfecting a cell to introduce an exogenous material into the cell. The method includes exposing the cell to a region of unsteady flow in the presence of an electric field to encourage introduction of the exogenous material into a cell without lysing the cell.

Disclosed are flow devices and methods for electroporation, which allow controlling the throughput of electroporation, for example by operating the electroporation process at selected throughput or operating at an increased or decreased level of throughput compared to a reference level of throughput by scaling a subset of electroporation parameters, while allowing maintaining cell viability and transfection efficiency.

Disclosed are microfluidic flow-based electroporation systems that have a flow device, an electrical control module, a fluid delivery module, and a multi-well module. The systems can be used in methods of selecting an electroporation parameter, and in methods of electroporating cells using the selected parameters.

Systems and methods are provided for labelling nucleic acids in a cell of a cell culture or of a tissue. The systems and methods include contacting the cell culture or tissue with a first label and applying an electrical field to the cell, thereby increasing the permeability of the cell membrane, allowing the first label to be introduced into the cell. The cell culture or tissue can be disposed on a multielectrode array, and the electrical field can be applied by operating one or more electrodes of the array that are proximate to (e.g., beneath) the cell in order to control the location of the cell whose permeability is increased and/or to control the timing of such permeability increase.
