Apparatus, systems and methods for the adaptive passage of a culture of cells and apparatus and methods for dissociating cell colonies are described. The systems may include an imaging module, a pipette module, a handling module, and/or a stage module. Coordinated operation of the modules, optionally in an automated manner, is effected by at least one processor based on one or more characteristics of the culture of cells calculated from one or more images captured at more than one time point. A first apparatus for adaptive passage of a culture cells includes an imaging module and at least one processor, which apparatus may be included in the systems or used in the methods. A second apparatus for dissociating cell colonies, may also be included in the systems or used in the methods, includes impact bumper(s) collidable with impact bracket(s) to transmit a dissociative force to a culture of cells.

Provided is a culture vessel for adherent cells that has a large culture portion surface area and ensures easily dissociating and recovering cells without consuming a medium or a dissociation solution more than necessary. The bag-shaped adherent cell culture vessel made of flexible packaging material includes a vessel body portion having a first vessel wall and a second vessel wall and one or more injecting/ejecting ports. The vessel body portion has an intermediate culture wall between the first vessel wall and the second vessel wall. A culture chamber is disposed in each of between the first vessel wall and the intermediate culture wall and between the second vessel wall and the intermediate culture wall, and a flow passage communicating between the respective culture chambers is disposed.

The embodiments according to the present disclosure provide a protective solution, a kit, and a method for isolating mitochondria. The kit includes an extraction tube, a protective solution, and a suction needle. The extraction tube is used to contain cells. The protective solution is used to mix with the cells in the extraction tube to form a mixture solution, and the osmolarity of the protective solution is greater than 0 and less than or equal to 220 mOsm/L. The suction needle is used to suck the mixed solution back and forth to facilitate the release of mitochondria from cells. This method and the protective solution may isolate mitochondria from cells with high efficiency in a simple and convenient way, and the isolated mitochondria have excellent good function.

An apparatus for sampling a cell culture includes a sampler for connecting to a bioreactor with a fixed bed including the cell culture. A releasably attached sample portion for positioning within or adjacent the fixed bed includes a substrate on which cells may be grown and then removed from the bioreactor to provide an indication of cell growth. A kit for sampling a cell culture bed of a bioreactor includes the sampler for sampling the cell culture bed with the releasably attached sample portion, along with a container adapted to detach the sample portion from the sampler. A method of obtaining a sample of a cell culture in a bed within a bioreactor includes positioning a sampler positioned at least partially in or adjacent to the bed to promote the growth of cells on a releasably attached portion of the sampler, withdrawing the sampler from the bioreactor, and detaching the portion of the sampler.

The invention relates to a microfluidic poration device having narrow channels slightly smaller than the width of a target cell, wherein the channels are lined with a plurality of nanospikes in a row extending down the middle of the channel, i.e. in a row parallel to the sides of the channel. In one embodiment, one channel may have 2 nanospikes (or 2 nanolancets). Thus, in particular embodiments, the invention provides microfluidic poration devices capable of simultaneously squeezing cells while piercing holes in their membranes for allowing foreign molecules into cells. The holes in porated cells spontaneously close after exiting the channels, thus entrapping the foreign molecules inside of the target cells. This porated cell population has approximately a 95% viability with greater than 50% containing at least one foreign molecule.

A method of forming a tissue or an organ, including: disposing, in a support medium in a gel state, a composition comprising a live biologic; changing a state of the support medium from the gel state to a solid state; and supporting, in the support medium at the solid state, the live biologic in the composition.

Provided is a technique for detecting a cell-derived substance with high sensitivity without destroying cells. A cell detection device of the present disclosure includes: a medium adding device configured to add a part of a prepared culture medium to a culture container holding cells to be detected; a medium collection device configured to collect the culture medium from the culture container; and a detection device configured to detect light from the luminescent reagent mixed with the collected culture medium.

Delivering a payload across a plasma membrane of a cell includes providing a population of cells and contacting the population of cells with a volume of an aqueous solution. The aqueous solution includes the payload and alcohol content greater than 5 percent concentration. The volume of the aqueous solution may be a function of exposed surface area of the population of cells, or may be a function of a number of cells in the population of cells. Related compositions, apparatus, systems, techniques, and articles are also described.

A cell sheet transfer device and a cell sheet processing equipment. The cell sheet transfer device includes a first tubular body; a second tubular body at one end of the first tubular body and connected thereto; and a cell shovel at the end of the first tubular body and on one side of the second tubular body. A free end of the cell shovel is beyond a free end of the second shovel body.
