The invention discloses a multi-layer cell freezing vial and method of obtention thereof. The method of obtention is a cell freezing and thawing process that avoids the need of incorporating new fresh medium to the thawed cells for the dilution of the cryoprotective agent. This is achieved by the previous freezing of an extra layer of culture medium in addition to the frozen cell solution containing said cryoprotective agent. At the time of thawing, the culture medium and the cell solution mix themselves, turning the concentration of said cryoprotective agent to a non-toxic dilution and achieving the effective exclusion of said cryoprotective agent from the living cells.

An automated system and method of preparing oocytes, embryos, or blastocysts for cryopreservation. The method entails delivering two or more solutions into a container holding oocytes, embryos, or blastocysts, and controlling the flow of the solutions to gradually change the concentration of cryoprotectants and dehydrating agents in the container to minimize shock to the oocytes, embryos or blastocysts.

Compositions for and methods of manufacturing a fucosylated cell population are provided. The method may include expansion of the cells and/or cryopreservation of the cells under conditions that retain optimum levels of cell surface fucosylation.

The present disclosure relates, in general, to a media, e.g., a serum replacement, media supplement, complete media or cryopreservation media, comprising a base physiological buffer and liposomes comprising cholesterol, phosphatidylcholine and fatty acids. It is contemplated that media provides advantages to improve cell growth in culture compared to cells cultured not using the serum replacement described herein.

Provided herein are methods of freezing mammalian cells for storage or improving thaw recovery of cell banks comprising freezing mammalian cells in a freezing medium having a pH of 6.7 to 8.5.

Disclosed herein are methods for cryopreserving cells and tissues under clinical conditions, allowing production of viable cell products suitable for transplantation.

Described herein are 3-dimensional clusters of reaggregated cells comprising cells reaggregated from at least two different cell sources, such as different cell types, different donors, and combinations thereof. Methods of making, using, and cryopreserving these 3-dimensional clusters of reaggregated cells are also described herein.

A cell composition composed of spermatogonial stem cells, Sertoli cells, Leydig cells and optionally peritubular cells, is provided, as is a culture composition, artificial testicular construct, hydrogel composition, and device containing the same. A method for using the device as a physiologically relevant in vitro model of human testicular function to screen compounds for pharmacological or toxicological activity is also provided.

The present invention is a method of freezing cells comprising the steps of incubating said cells in a solution comprising a cryoprotective agent, concentrating the cells resulting from the previous step withdrawing the eluent essentially free of cells, and freezing the resulting concentrated cells. The cells frozen by the invention's method render a high post-thawing viability, reduce cryoprotectant related toxic events and promote cells life in a suspension state after thawing. The invention also comprises the container comprising the frozen cells.

A method and apparatus for the processing of tissue and cellular material during cryopreservation and/or processing for microscopy. The method and apparatus maximizes heat transfer coefficients by using liquid-free cryopreservation protocols and maximizing glass transition characteristics through increasing pressure during cryopreservation. Cooling rates combined with megapascal pressures reduced the required concentration of cryoprotective agents (CPAs) needed for ice-free cell and tissue cryopreservation.
