A biomaterial preserving composition including a thermos-reversible polymer is provided. The composition is capable of solving problems related to conventional biomaterial preserving liquids not being sufficient for the survival or functional retention of cells in a biomaterial, and having many restrictions in preservation conditions such as the preservation temperature and the preservation treatment, resulting in a bottleneck for widespread use of cell therapy.

Viable disc regenerative composition and method of manufacture and use

A viable disc regenerative composition has a micronized material of nucleus pulposus and a biological composition made from a mixture of mechanically selected allogeneic biologic material derived from bone marrow having non-whole cellular components including vesicular components and active and inactive components of biological activity, cell fragments, cellular excretions, cellular derivatives, and extracellular components; and wherein the mixture is compatible with biologic function and further includes non-expanded whole cells. The biological composition is predisposed to demonstrate or support elaboration of active volume or spatial geometry consistent in morphology with that of disc tissue. The viable disc regenerative composition extends regenerative resonance that compliments or mimics disc tissue complexity.

CAPILLARY ASSISTED VITRIFICATION PROCESSES AND MATERIALS FOR PRESERVATION OF BIOLOGICAL SAMPLES
20230082652 · 2023-03-16 ·

Disclosed is a process for storage of nucleic acids from a biological sample. The process comprises providing a biological sample comprising one or more cells containing nucleic acids therein; contacting the biological sample with a vitrification medium comprising a vitrification agent and a lysing agent to form a vitrification mixture; vitrifying the vitrification mixture to generate a storage-stable sample. In various aspects, the storage-stable sample can be stored at a temperature above cryogenic temperatures, such as at room temperature, for 20 days or more.

Composition for cryopreservation of bovine reproductive cells and cryopreservation method thereof

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.

NUCLEIC ACID AND CELL PRESERVATIVE COMPOSITIONS AND METHODS OF USE

This disclosure is directed to nucleic acid and cell preservative compositions. Methods of preserving nucleic acids and/or cells in a blood or other biological sample, and kits for preserving nucleic acids and/or cells in a blood or other biological sample are also described.

Porous material for the inclusion of cytologic preparations, process for obtaining the same and its use

The present invention relates to a porous material for inclusion of cytological preparations such as for example the material taken from procedures of fine needle aspiration with high effectiveness level. The effectiveness consists in quantitative and qualitative advantages: the proposed porous material has a high affinity for the cellular material which is captured and kept in the meshes by forming a kind of tissue without losing cellular elements thus with a quantitative advantage with respect to the traditional methods. Moreover, the material proposed in the patent is provided with wide cells delimited by thin meshes, this allows a wide diffusion of the fixative by optimizing the morphology preservation of the cytological sample; such qualitative advantage translates into optimum yield of the ancillary methods for studying the pathology.
