Definitions
- the present invention relates to the field of regenerative medicine, that is, a medical technology for transplanting in place of a patient's own organs or tissues that do not function properly and restoring normal functions. More specifically, the present invention relates to a method for preparing a tissue graft for transplantation by removing cellular components from living tissue derived from an animal or fixing the tissue using a fixative, typically glutaraldehyde. (Background technology)
- Implants for transplantation have been created by chemically treating living tissue with a fixative such as gludealdehyde, or by removing cellular components from living tissue, and are widely used in clinical applications.
- a fixative such as gludealdehyde
- a heterologous biological valve is a porcine heart valve or a pericardium immobilized with glutaraldehyde to reduce immunogenicity.
- this xenogeneic biological valve has excellent anticoagulant properties
- cryopreserved tissue banks have been developed, and the same type of cryopreserved valves provided by cadaver are being used clinically.
- This type of valve is said to be more thromboresistant than mechanical valves, more durable and more infectious than other types of biological valves.
- the major shortcoming is the absolute lack of supplies.
- a xenograft of the same type or different type from which the cell components have been removed can be used to inoculate the patient's own cells, proliferate autologous cells within the cell debris, and transplant it as a hybrid regenerated tissue. Used.
- An object of the present invention is to improve the above-mentioned problems of the prior art. That is, first of all, the removal of cell components, cells and viruses inside large tissues that cannot be achieved by chemical treatment is achieved.
- processing must be performed without deteriorating the biomechanical properties of the treated tissue.
- processing must be simple and quick.
- the present invention provides a method for treating a living tissue, which comprises irradiating a living body tissue derived from an animal immersed in a treatment solution with a mouth wave while maintaining a temperature of 0 ° C to 40 ° C. provide.
- FIG. 1 is a schematic diagram showing an example of an apparatus for carrying out the present invention.
- Fig. 2 Cross-sectional photograph of porcine heart valve tissue. The left shows the processing according to the conventional method, and the right shows the processing according to the present invention using the combined use of Mic mouth wave irradiation. In the conventional treatment, cell nuclei remain in the deep part of the tissue (lower left of the photograph).
- Fig. 3 Graph showing the removal efficiency of Triton X-100 from the bush heart valve from which cells were removed at Triton X-100. According to the method of the present invention by microwave mouth wave irradiation, it was possible to remove Triton X-100 in about one tenth of the time of the conventional method.
- the method of the present invention comprises the steps of: removing cell components from living tissue; Can be applied to the process of creating In this case, water, a hypertonic solution, a hypotonic solution, a surfactant solution, an enzyme solution, a medium, or a liquid containing a small amount of an organic solvent is used as a treatment solution.
- a solution of a chemical fixing agent such as glutaraldehyde is used.
- the treatment liquid spreads over the entire surface by diffusion and permeation from the sample surface.
- Mic mouth wave irradiation can reduce the time required for the treatment liquid to penetrate deep into the tissue to about one-tenth that of the conventional method, greatly improving the processing efficiency. The contamination of the sample during that time can be prevented.
- a cell is removed from a tissue to prepare a graft, it is possible to remove a cell nucleus from a deep part of the tissue in a short time, which was impossible or difficult with the conventional methods.
- Microwave treatment is applied to tissue fixation, bone decalcification, defatting, immunohistochemistry, etc. in the histopathology field.
- microwave mouth wave irradiation to the preparation of implants.
- a sample to be treated is placed in a glass or plastic sample container that transmits microwaves, and in the cell removal treatment, a surfactant, a low-level solution, or a harmonic solution is used.
- a treatment solution such as, for example, and a glue aldehyde or other chemical fixative solution for cell fixation so that the sample is completely immersed.
- Microwave irradiation is performed while controlling the temperature of the processed sample within the range of 0 to 40 ° C.However, in general, irradiation of microwaves increases the sample temperature. Must cool the sample. For this purpose, for example, the use of a commercially available micro-mouth wave rapid sample processing device is effective.
- This apparatus is modified and used so as to circulate an antifreeze liquid cooled by a cooling device outside the microwave oven around a sample container in a microwave oven for irradiating a microwave.
- the sample temperature during microwave irradiation can be controlled to 0 to 40 ° C. Is possible.
- the temperature Unlike the histopathology field, in the case of living tissue for transplantation, it is necessary to prevent denaturation of the constituent matrix in order not to change the biomechanical properties. The temperature must not exceed 40 ° C.
- FIG. 1 is a schematic diagram showing an example of an apparatus for carrying out the present invention.
- the apparatus consists of a microwave oven 1 equipped with a magnetron 12. Inside the oven, a cooling tank 2 containing a cooling antifreeze 21 is provided, and a sample container 3 is placed almost at the center of the cooling tank 2.
- the sample container 3 is filled with the processing liquid, and the sample, that is, the living tissue 4 to be processed is immersed therein.
- the cooling tank and the sample container 3 are made of a material that transmits microwaves such as glass and plastic, for example, polypropylene and polystyrene.
- the irradiation of the microphone mouth wave heats the processing solution 3 1 and thus the sample 4 and irreversibly thermally denatures the constituent matrix of the sample.
- the coolant 2 1 warmed in the cooling bath 21 is returned to the heat exchanger 72 of the cooling device through the conduit 6, cooled again, and then pumped to the cooling bath 11 via the conduit 5 7 1 Returned by
- the temperature of the coolant in the bath 21 is sensed by the sensor 11 and the temperature is kept constant at a constant temperature in the range of 0 ° C to 40 ° C, for example, 20 ° C.
- the operation time of the magnetron 12 is intermittently and automatically controlled by the roller 13. Stirring fans and other means can be installed to evenly irradiate the microwave.
- the method of the present invention can also be used in combination with known methods for removing cellular components from tissue. For example, after performing a pretreatment for removing cells in a tissue using a surfactant or an enzyme, washing for removing a chemical solution remaining in the tissue piece can be performed under microwave irradiation.
- Example 2 The efficiency of the washing process for removing cell components from the treatment of soft tissue for transplantation from donors with brain death or heart death, or from xenogeneic animals such as pigs and pests can be dramatically increased. . In addition, a significant decrease in antigenic causative substances can be achieved.
- Example Similar to the above, bone, cartilage, teeth, and other hard tissue processing can be performed.
- Example Among animal and plant-derived tissues, those containing cells can be used for cell destruction treatment.
- Pig hearts were purchased from pig breeding grounds and transported at 4 ° C. The time of warm ischemia at the time of removal of the heart was set within 20 minutes. The pulmonary valve and blood vessels were removed and washed with Hank's solution. Triton X _ which is a surfactant The sample was immersed in a 1% aqueous solution of 100% aqueous solution, and the mouthpiece of the microphone was intermittently irradiated at 20 ° C for 48 hours using the device shown in the schematic diagram in Fig. 1 to remove the donor cells. . After the treatment, it was washed and removed with phosphate buffered saline. Histological evaluation was performed by observing the tissue section of the treated sample with a light microscope using HE staining. As a result, in the porcine pulmonary artery leaflet tissue, as shown in Fig. 2, cells could be removed to the deeper part of the tissue with the use of the combination of microwave irradiation as compared to the case without the combination.
- porcine heart valves purchased from porcine pig breeding grounds were immersed in a 1% aqueous solution of Triton X-100, a surfactant, for 1 hour to remove cells. Then, it was immersed in phosphate-buffered saline and irradiated with microwaves at 10 ° C intermittently for 48 hours. As a result, as shown in Fig. 3, conventional methods that do not irradiate Mic mouth waves required about three weeks to remove the cytotoxic Triton X-100 solution. By irradiating the microphone mouth wave, it was possible to greatly reduce the processing time by several days.
