Provided are a blood bag system and a blood treatment method capable of securely and efficiently obtaining a medium specific gravity blood component having a sufficiently low content rate of a light specific gravity blood component. In a blood bag system (10) used for a blood treatment method, in a transfer completed state in which whole blood in a first bag (12) is centrifuged to transfer blood plasma to a second bag (14) through a first transfer tube (24) and transfer red cell concentrates to a third bag (16) through a second transfer tube (26), a buffy coat is left in the first bag (12). In the transfer completed state, when a platelet added solution is transferred from a fourth bag (18) to the first bag (12) on which a centrifugal force acts through a third transfer tube (28), blood plasma in the buffy coat is discharged from the first bag (12).

The invention relates to a medical device for preservation of corneal tissue (3) that has been obtained beforehand by sampling, the device comprising a base (11), at least one side wall (12), and means for receiving and blocking the corneal tissue (3), characterized in that the device additionally comprises an applanation lid (13) for covering an opening of the device opposite the transparent base (11), the applanation lid (13) comprising: a transparent window (131), and a support (132) between the window (131) and the side wall (12), the support (132) comprising means for moving the window (131) in translation with respect to the side wall (12) of the device.

A biological specimen of a subject is handled and tracked for a procedure involving that specimen. Prior to initiation of the procedure, a first procedure data structure (PDS) is generated. The first PDS binds an identifier corresponding to the subject with an indicator of a procedure to be performed on the specimen and identifiers of a specimen container and a specimen holder that physically contacts the biological specimen, as well as a scheduled time for the procedure. A schedule of a plurality of PDSs including the first PDS, is displayed on a display device of a graphical user interface. Following initiation of the procedure, the first PDS is updated based on user input, and after the procedure, at least a portion of the first PDS, as updated, is stored in a database in conjunction with other PDSs respectively associated with other completed procedures.

A device to aid in the production and regeneration of tissues and organs, standing alone, or on or inside of the human body, with a method of fabrication of tissues and organs and use of the device.

Provided herein is technology relating to cryopreservation and particularly, but not exclusively, to devices, systems, and methods for cryopreservation of biological materials such as oocytes, zygotes, and embryos. In particular, provided herein are methods of using microfluidic devices to exposing biological material to a vitrification solution having a time dependent concentration of a cryoprotectant agent.

Embodiments of the present invention may provide effective processing of materials through phase transitions with a mobile phase transition device which may have a frozen storage area and a thawing area and which can be used to thaw biological materials near a recipient of the materials. A mobile phase transition device may be automated so that the thawing of materials can precisely follow thawing protocols.

Disclosed herein are cellular cassettes for the storage, collection, and analysis of biological samples. The cellular cassette can enable easy sample collection and sealing of microwell arrays with semi-permeable membrane for stable storage and future processing of single cells. Also disclosed herein are systems and kits comprising one or more described cassettes. The described cassettes, systems, and kits can be used to create barcoded, single-cell sequencing libraries. Further described herein are methods of using the cassettes, systems, and kits.

Systems and methods of the invention generally relate to prolonging viability of bodily tissue, especially lung tissue, through the use of an expandable accumulator to maintain a constant pressure within the lumen of the organ even during external pressure fluctuations due to, for example, flight. Systems and methods may include prolonging donor organ viability in storage through the use of an organ container that mimics the geometry and orientation of the organ in vivo.

In a method of ventilating excised lungs, a ventilation gas is supplied to an airway of a lung and a vacuum is formed around the lung. A quality of the vacuum is varied between a lower level and a higher level to cause the lung to breathe, while the pressure of the ventilation gas supplied to the airway is regulated to maintain a positive airway pressure in the airway of the lung. The vacuum may be cyclically varied between the two vacuum levels. The levels may be maintained substantially constant over a period of time, or one or both of the lower and higher levels may be adjusted during ventilation. The lung may be placed in a sealed chamber, and a vacuum is formed in the chamber around the lung.

Provided is a method for producing platelets, in which damage to platelets is suppressed compared with a method in which platelets are separated using a filter from a megakaryocyte culture, and then the platelets are concentrated using a hollow fiber membrane and are further washed using the hollow fiber membrane, and purified platelets can be produced in a shorter period of time compared with the time that is taken to perform the above-described method so as to reduce damage to platelets. The method for producing purified platelets of the present invention includes a concentrating step of concentrating a megakaryocyte culture, and a centrifuging step of centrifuging platelets from an obtained concentrate.
