Provided are a vehicle body assembling method and a vehicle body assembling apparatus which allow a simple configuration in the vicinity of the connecting portion between an upper jig and a lower jig and allow an increase in the efficiency of assembling work (welding work). A vehicle body assembling apparatus is equipped with a jig for supporting vehicle body components in a preassembled position, the jig comprising an upper jig and a lower jig which are connected to each other in at least two places. Each of the connection places is provided with a connecting means for fixing a three-dimensional coordinate position while allowing uniaxial turning. The vehicle body assembling apparatus is also equipped with a conveying means for conveying the upper jig which supports the vehicle body components, and reduces the load applied to the lower jig from the upper jig when connecting the upper jig to the lower jig.

Provided herein is a placental product comprising an immunocompatible chorionic membrane. Such placental products can be cryopreserved and contain viable therapeutic cells after thawing. The placental product of the present invention is useful in treating a patient with a tissue injury (e.g. wound or burn) by applying the placental product to the injury. Similar application is useful with ligament and tendon repair and for engraftment procedures such as bone engraftment.

The object is to provide a method for cryopreserving and thawing cells with maintaining high viability and high activity, which is applicable to highly active NK cells. A method for treating cells, which comprises the following steps of: (1) collecting in vitro-activated cells in a medium for cell culture; (2) suspending the collected cells in a solution for cryopreservation; and (3) freezing the suspended cells. The step (1) preferably includes a treatment with a medium supplemented with any selected from the group consisting of a bile acid and phenylbutyric acid.

A device for aseptic delivery of biological material from a vial includes a tubular barrel, a filter assembly, and a dispersion funnel assembly. The tubular barrel includes a receiving end to accept at least a portion of the vial within the tubular barrel, and a dispensing end opposite the receiving end. The filter assembly is fluidly connected to the dispensing end of the tubular barrel. The dispersion funnel assembly is configured to connect to the vial, and to be disposed at least partially within the tubular barrel. The dispersion funnel assembly has an open configuration to disperse the biological material from the vial into the tubular barrel between the dispersion funnel assembly and the filter assembly, and a closed configuration to force the dispersed biological material through the filter assembly when the dispersion funnel assembly is moved toward the dispensing end of the tubular barrel.

A non-human mammalian model for human diseases or disorders comprising a non-human neutrophil depleted mammalian host engrafted with a human skin equivalent (huSE) and human immune cells.

The present disclosure provides methods for bulk droplet vitrification of cells, compositions including the vitrified droplets, and systems for performing the methods for bulk droplet vitrification cells.

The present invention relates to a medium composition for the cryopreservation of cells, which exhibits excellent cell recovery rates, cell viability rates and cell activity after thawing, and a pharmaceutical composition comprising the medium composition and therapeutic cells. Also, the medium composition of the present invention allows for readily administering the cryopreserved therapeutic cells to a subject without additional procedures such as washing, separation, etc. Therefore, the composition may be used as an excellent medium composition for cell cryopreservation or as an excellent therapeutic composition.

The present invention discloses a method for screening, activating, amplifying and cryopreserving mesenchymal stem cells in vitro and establishing a cell bank of mesenchymal stem cells. The method includes the following steps: using a dedicated primary screening medium of mesenchymal stem cells for first-stage screening culture to obtain purified mesenchymal stem cells; using a dedicated activation and amplification medium of mesenchymal stem cells to perform second-stage activation and large-scale amplification culture on the purified mesenchymal stem cells to obtain a large number of mesenchymal stem cells with activation functions; using a dedicated cryopreserving fluid of mesenchymal stem cells to cryopreserve the stem cells and performing preservation according to ABO/RH typing and HLA typing; and establishing an information file for retrieval to construct a mesenchymal stem cell bank.

A device for retaining a biological sample for performing a cryoprocedure on a biological sample having a tubular member having a lumen extending therein, the lumen configured to receive the biological sample. A retainer is couplable to a distal end of the tubular member, the retainer having a perforated member having at least one orifice, the at least one orifice having a dimension smaller than a dimension of the at least one biological sample to prevent exit of the biological sample from the tubular member, wherein the perforated element is configured to allow inflow of liquids to communicate with the lumen containing the biological sample.

A purpose of the present invention is to provide a composition for preserving a sample, in particular, a composition able to preserve cells or a tissue without causing a change in the state of cells. Another purpose of the present invention is to provide a sample preservation method for preparing a suspension containing a target object from a preserved sample, and a method for analyzing a target object in a sample. The present disclosure provides a sample preservation composition containing albumin and lactic acid or a salt thereof. The concentration of sodium ions in the composition is 50-300 mmol/L. Further provided are a method for preserving a sample using the composition, a method for preparing a sample suspension, and a method for analyzing a target object in the sample suspension.
