DEVICE FOR VITRIFICATION PRESERVATION OF CELLS OR TISSUES
The present invention aims to provide a device for vitrification cryopreservation enabling easy and reliable vitrification cryopreservation of a cell or tissue. The device for vitrification cryopreservation of a cell or tissue of the present invention includes a support and a vitrification solution absorber including at least an adhesive layer and a vitrification solution absorbing layer in the given order on the support. The device includes a portion with no adhesive layer disposed between the support and a portion of the vitrification solution absorbing layer configured to hold a cell or tissue.
Cryopreservation of cells and subcellular fractions
The invention provides cryopreserved compositions of cells, wherein the compositions are advantageously in the form of self-sustaining bodies that can be individually handled and combined independently of a container, allowing for easy customization of the eventual pooled preparation. The invention also provides pre-pooled stacks of the self-sustaining cryopreserved compositions for eventual thawing to produce pooled preparations of cells. A mold and methods for forming the self-sustaining bodies are also provided. The invention is also concerned with methods of forming pooled preparations of cells using single-cryopreserved compositions of cells.
Desiccated biologics and methods of preparing the same
The present invention provides compositions comprising desiccated biologics comprising a cell, protein, virus, nucleic acid, carbohydrate, or lipid, or any combination thereof, along with at least one membrane penetrable sugar, and at least one membrane impenetrable sugar, wherein the moisture content is from 5% to 95%, and to methods of preparing the same, and to methods of treating animals using the same.
Administration and monitoring of nitric oxide in ex vivo fluids
Described are systems and methods for monitoring administration of nitric oxide (NO) to ex vivo fluids. Examples of such fluids include blood in extracorporeal membrane oxygenation (ECMO) circuits or perfusion fluids used for preserving ex vivo organs prior to transplanting in a recipient. The systems and methods described herein provide for administering nitric oxide to the fluid, monitoring nitric oxide or a nitric oxide marker in the fluid, and adjusting the nitric oxide administration.
COMPOSITION FOR IMPROVING STABILITY OF STEM CELLS
The present invention relates to a composition capable of improving storage stability of stem cells. More specifically, the present invention relates to a composition which contains a serum or a plasma for improving cold storage stability of stem cells. The composition for improving storage stability of stem cells according to the present invention can maintain a survival rate of over 90% for at least 9 days without changes in the properties, the number or the size of the stem cells, and thus is useful in the long-term transport of stem cells for cell therapy and the preparation of cell therapeutics injection products having an excellent effect.
Method and system for filling and venting a device for extracorporeal blood treatment, with stepped flooding of a filter
A method for filling and venting a device for extracorporeal blood treatment is disclosed, such as a patient module in a heart-lung machine, without attached patient. A filling liquid from a filling liquid container located higher than the device flows by gravity via a venous side of the system into a reservoir and flows onwards into a blood pump located at the lower end of the reservoir, wherein a first controllable valve (HC1) for a venting line of a filter is opened and, after the response of an upper filling level sensor in the reservoir, is closed. An upper level of the filter is positioned higher than the upper filling level sensor, and a start-stop motion of the blood pump is performed, as a result of which a stepped flooding of the filter is made providing for an advantageous de-airing of the device.
SYSTEMS AND METHODS FOR CRYOPRESERVATION OF CELLS
A fluid sample vessel includes inlet and vent tube fittings formed at one end of a container with an opposite open end closed by a needle septum. A support cap is removably engaged to the container to support the container and protect terminal ends of inlet and vent tubular branches coupled to the fittings. The support cap includes a pair of opposite legs with outwardly directed tabs for mounting within a centrifuge while supporting the cryopreservation container.
Novel Methods for Freeze-drying and Rehydrating Biologics
The present invention relates generally to the fields of immunology and vaccine technology. More specifically, the present invention relates to methods for freeze-drying biological preparations, including peptides, antigens, antibodies, and especially, cells. Importantly, the disclosed methods preserve the viability, infectivity and immunogenicity of cells from the Apicomplexa phylum, the Sarcocystidae family, and in particular, cells from the Toxoplasma genus.
Protective solutions for organs
Described is a protective solution for avoiding ischemic, storage or ischemia/reperfusion to organs, or to isolated cell systems, or to tissue components after perfusion, surgery, transplantation, or cryopreservation and subsequent reperfusion, which contains alkali ions, and if need be also alkaline earth ions as the electrolyte, a buffer e.g. on a histidine derivation basis, as well as a polyol and/or a saccharide, has an osmolarity of about 290 mosm/l to about 350 mosm/l, as well as a pH value of about 6.8 to about 7.4, and to which hydroxamic acid, and/or one or more hydroxamic acid derivatives are added.
EXPANDED UTILITY OF RED-CELL DERIVED MICROPARTICLES (RMP) FOR TREATMENT OF BLEEDING
Red blood cell membrane derived microparticles (RMP) are safe, economical, effective hemostatic agents in the treatment of a wide range of bleeding conditions and can, therefore, be considered as universal hemostatic agents. Effective RMP are produced from red blood cells using a high-pressure extrusion membrane shear process. The RMP can be lyophilized after production and retain activity even when stored at room temperature. RMP can be administered to original donors (autologous treatment), thus avoiding transfusion complications, or can be administered to blood type compatible recipients. RMP produced from type O, Rh negative red cells can be given to any person regardless of blood type. RMP can be administered to reduce excessive bleeding resulting from trauma, surgeries, invasive procedures and various bleeding disorders such as platelet disorders, either congenital or acquired, and coagulation disorders, either congenital or acquired. Administration of RMP prepared according to the invention demonstrates effectiveness in safely reducing bleeding.
