Methods for stabilizing blood samples, e.g., clinical blood samples, for storage or transportation before use.

The present invention relates to methods of cryopreservation and compositions for use in such methods where the methods utilise non-Newtonian fluid properties of the cryopreservation medium to modulate the viscosity of that medium to deliver an improved cryopreservation process.

The present invention provides a method for evaluating effectiveness of a cell therapeutic agent. When using TGF-β and/or TSP-1 expression level(s) in: (a) a first population of transformed mammalian cells with TGF-β; and (b) a second population of untransformed mammalian cells with the same gene, respectively, as a criterion for determining effectiveness of a cell therapeutic agent, and whether or not expression thereof, it is possible to definitely determine the therapeutic efficacy of each cell therapeutic agent prior to initiation of the treatment. In addition, since use of a cell therapeutic agent without therapeutic effects is avoided, undesired procedures and side effects may not be entailed.

The present invention relates to a cryoprotecting agent comprising a cryprotectant being one or more of: dextrin, dextran, isomaltooligosaccharide and derivatives thereof, cryoprotecting and cryopreserved compositions, uses thereof, and methods of cryopreservation.

The present disclosure provides for a cell stabilizing medium which comprises gelatin. The cell stabilizing medium help maintain cell viability, e.g., after thawing of a biological material post-cryopreservation.

The present invention provides methods for isolating and cryopreserving tumor infiltrating lymphocytes (TILs) and producing therapeutic populations of TILs, including methods via use of a kit and a semi-automatic device for aseptic disaggregation, enrichment, and cryopreservation of a resected tumor prior to expansion of the TIL population. The present invention also provides methods for expansion, and/or stabilization of TILs, for instance UTILs, compositions involving the same and methods of treatment involving the same.

Provided is a novel means of inhibiting fertilized egg fragmentation. The present invention provides an inhibitor of fertilized egg fragmentation, said inhibitor comprising selenoneine or ergothioneine, a tautomer or dimer thereof, or a pharmaceutically acceptable salt of the same as an active agent.

Disclosed are compounds and compositions for slowing, preventing, or reversing platelet damage, particularly as may occur during blood banking or during refrigeration of platelets. Also disclosed herein are methods for storing platelets and methods for improving platelet survival upon transfusion with one or more compounds or compositions as described herein.

The present disclosure provides a method of producing a population of lyophilized cells, comprising: (a) freezing a composition comprising a population of cells, an aqueous component, a polyol, a sugar, and a polysaccharide; and (b) removing at least 90% of the aqueous component from the frozen composition to produce the population of lyophilized cells. On some embodiments, the disclosure provides a method of producing a population of reconstituted viable cells, comprising: (a) freezing a composition comprising a population of cells, an aqueous component, a polyol, a sugar, and a polysaccharide; (b) removing at least 90% of the aqueous component from the frozen composition to produce the population of lyophilized cells, and (c) resuspending the population of lyophilized cells in a reconstitution agent to form a reconstituted composition, wherein at least 1% of the cells are viable.

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.
