摘要： A method for processing and preserving an acellular collagen-based tissue matrix for transplantation is disclosed. The method includes the steps of processing biological tissues with a stabilizing solution to reduce procurement damage, treatment with a processing solution to remove cells, treatment with a cryoprotectant solution followed by freezing, drying, storage and rehydration under conditions that preclude functionally significant damage and reconstitution with viable cells.

摘要： A method of processing an acellular tissue matrix to give a particulate acellular tissue matrix includes: cutting sheets of dry acellular tissue matrix into strips; cryofracturing the dry acellular tissue matrix strips at cryogenic temperatures; separating the resulting particles by size at cryogenic temperatures; and freeze drying the fraction of particles desired size to remove any moisture that may have been absorbed to give a dry particulate acellular tissue matrix. Rehydration of the dry particulate acellular tissue matrix may take place just prior to use. The particulate acellular tissue may be applied to a recipient site, by way of injection, spraying, layering, packing, in-casing or combinations thereof. The particulate acelluar tissue may further include growth and stimulating agents selected from epidermal growth factor, fibroblast growth factor, nerve growth factor, keratinocyte growth factor, platelet derived growth factor, vasoactive intestinal peptide, stem cell factor, bone morphogetic proteins, chondrocyte growth factor and combinations thereof. Other pharmaceutically active compounds may be combined with the rehydrated particulate material including: analgesic drugs; hemostatic drugs; antibiotic drugs; local anesthetics and the like to enhance the acceptance of the implanted particulate material. The particulate material product may also be combined with stem cells selected from mesenchymal stem cells, epidermal stem cells, cartilage stem cells, hematopoietic stem cells and combinations thereof.

摘要： The present invention provides methods for in vitro production of clinically useful quantities of differentiated human blood cells. In various embodiments of the present invention, immortal pluripotent cells are used to produce differentiated blood cell populations using a cell production device. In a specific embodiment, the device is a sequential series of bioreactors utilizing growth media containing specific combinations of maintenance-, proliferation- or differentiation-promoting factors that maintain, expand and promote the maturation and differentiation of the desired cell types. The immortal pluripotent cells can optionally be genetically modified so as to remove histcompatibility or blood group antigens.

摘要： A method and apparatus for ultrarapid cooling of tissue samples against a chilled cryogenic surface. The cryogenic surface is enclosed in an ultra-high hydrocarbon free vacuum chamber during cooling of the cryogenic surface by a helium cryopump or multiple-stage refrigerator. Dry helium gas is introduced from an external source to raise the chamber pressure just prior to slamming or plunging a sample against the cryogenic surface. The cryogenic surface is heated for regeneration or cleaning purposes between each successive sample. During heating and cleaning of the cryogenic surface, an evacuated thermal break functionally separates the surface from the helium cryopump or multiple-stage refrigerator used to cool the surface. After regeneration or cleaning the cryogenic surfce, dry helium gas is reintroduced into the thermal break from an external source, thereby enabling the helium cryopump or multiple-stage refrigerator to rapidly recool the cryogenic surface and repeat the cycle for sequential samples with minimal regeneration time between each sample.
