Abstract: A method of preserving functionality of an organ is disclosed herein, including removing a whole organ including vasculature from a donor, cryo-preserving the whole organ including vasculature, thawing the whole organ including vasculature so that at least a portion of cells contained therein resume biological activity, and introducing the whole organ including vasculature into a recipient so that a blood vessel in the vasculature is supplied with blood. Further disclosed herein is a method of preserving fertility of a patient undergoing a treatment expected to cause sterility, including removing at least one whole gonadal organ including vasculature from the patient, preserving functionality of the gonadal organ as described herein, conducting the treatment and waiting for an effect thereof to subside, and introducing the gonadal organ into the patient.

Abstract: A method of preserving functionality of an organ. The method includes removing a whole organ and associated vasculature, cryo-preserving the whole organ, allowing a period of time to elapse, thawing the whole organ including vasculature and introducing the whole organ into a recipient so that the organ is supplied with blood by vasculature belonging to the recipient. Further disclosed is a method of preserving fertility of a patient undergoing a treatment expected to cause sterility. The method include removing a whole gonadal organ from the patient, cryo-preserving the whole gonadal organ, conducting the treatment and waiting for an effect thereof to subside, thawing the whole gonadal organ and introducing the whole gonadal organ where it is supplied with blood by the vasculature system of the patient.

Abstract: Provided is a preservation solution for preserving biological material at low temperature including one or more polyphenols and a method for preservation of biological material, the method includes adding the preservation solution to biological material, cooling the biological material and storing it under appropriate storing conditions. The present method may be used for hypothermic preservation or for cryopreservation, including freezing and lyophilization, and may be used with any biological material, including cells selected from RBC, WBC, MNC, UCB MNC and bacteria. In the case of RBC, also disclosed is a method for its freezing such that upon thawing, the material has less than 2% free hemoglobin.

Abstract: The claimed subject matter is based on the finding that it is possible to cryopreserve cancellous bone tissue with viable cells (after reconstitution by either thawing or rehydration), the viability after reconstitution being comparable to that of a fresh sample (without freezing) and of beneficial value for use in, for example, transplantation. Thus, provided is a method for cryopreserving a cancellous bone sample. The cryopreserved cancellous bone sample can be in dry form, for example, lyophilized. Also provided is a cryopreserved, in dry form, bone sample and the use of a cryopreserved bone sample; a method for identifying such cryopreserved cancellous bone tissue and uses thereof.

Abstract: The present invention generally concerns cell therapy and products for use in such therapy. Particularly, the invention provides a preserved cell preparation essentially free of one or more members of a group of cryoprotecting agents consisting of polyalcohols, DMSO and cryoprotecting proteins, the preserved cell preparation comprising somatic cells and at least one polyphenol, wherein upon reconstitution of cells in the cell preparation, at least a portion of said stem cells are viable, said portion being sufficient for use of the cell preparation in stem cell therapy. The invention also provides cells reconstituted from preserved somatic cells, and the use of the reconstituted cells in cell therapy. A preferred cell preparation in accordance with the invention comprises stem cells, preferably human stem cells.

Abstract: The invention provides a method for the sterilization of a biological preparation comprising desired viable biological entities. The method comprises irradiating a dried (e.g. freeze-dried) biological preparation with ionizing or UV radiation at an intensity and for a duration sufficient to reduce the amount or activity of living-matter contaminants in the biological preparation, the intensity and duration selected such that at least part of the desired biological entities in the sample remains viable. The method of the invention is particularly suitable for the reduction of the amount or activity of contaminants such as bacteria or viruses from biological preparations comprising red blood cells or platelets.

Abstract: There are provided a system and a method for cryopreserving a liquid biological material disposed in a bag having a longitudinal axis. The system comprises a bag holder for holding the bag, so that the biological material therein has a surface area S, and a volume V, a tank containing a cryogenic fluid, a mechanism for the immersion of the bag holder into the tank along the longitudinal axis, an opening in the tank for insertion therethrough of the bag holder, and a guide member extending from the opening into the tank. There are further provided a system and a method for warming a cryopreserved liquid biological material disposed in a bag.

Abstract: A method and a device for improved freezing of biological containing living cells is disclosed. Directional cooling coupled with agitation, preferably rotation, of the vessel containing the biological sample allows for the freezing of large volume samples at much greater rates than before. Whether a sample is large or not, the greater thermal homogeneity during the freezing process as well as the resulting crystal morphology yield a frozen sample which is exceptionally suited for lyophilization.
