Definitions
- the present invention relates to a technique for achieving destruction of donor cells, cell death, and virus inactivation from a biological tissue for transplantation.
- a tissue piece for transplantation is produced by chemical treatment of a living tissue with a fixing agent such as glutaraldehyde, or by removing cellular components from the living tissue, and is widely applied clinically.
- a fixing agent such as glutaraldehyde
- a heterogeneous biological valve is a buyu heart valve or ushi pericardium immobilized with glutaraldehyde to reduce immunogenicity. Although this heterogeneous valve is superior in anticoagulant properties,
- An object of the present invention is to improve the problems of the prior art as described above. That is, firstly, the removal of cellular components and cells and viruses inside a large tissue that cannot be achieved by chemical treatment, secondly, processing without sacrificing biomechanical properties, and third, It is a simple and quick sterilization of tissue.
- a method for treating a biological tissue for transplantation is utilized by utilizing the destruction of cell membranes, the death of bacteria, and the inactivation of viruses under high pressure. It was devised to be used as
- an ultrahigh hydrostatic pressure is applied to a transplantable animal-derived tissue in a medium so that the connective tissue is in contact with other components including cells while maintaining the structure and biomechanical properties.
- a method for treating a biological tissue for transplantation characterized by being separable from the body.
- Fig. 1 Cross-sectional picture of porcine heart valve tissue. Surfactant treatment for 24 hours on the left, high pressure treatment for 10 hours, 10 minutes on the right, surfactant treatment reveals cell nuclei remaining in the deep tissue (lower left).
- FIG. 2 Cross-sectional picture of porcine heart valve tissue. Surfactant treatment for 24 hours on the left, high pressure treatment for 100 hours on the right, 100 minutes at 100 minutes. In either case, the tissue is well preserved without any loosening of the tissue.
- Fig. 3 Processing time dependence of breaking strength of porcine heart leaflets. Surfactant treatment on the left, high pressure treatment on the right, 100 atm, and surfactant treatment, the breaking strength tends to increase with the treatment time, but no change is observed in the high pressure treatment.
- Fig. 4 Processing time dependence of elastic modulus of porcine heart leaflets. Surfactant treatment on the left, high pressure treatment on the right 1 0 0 0 atmosphere. In the surfactant treatment, the elastic modulus tends to increase with the treatment time, but no change is observed in the high pressure treatment.
- Fig. 5 Results of culturing for 1 day after high-pressure treatment of vascular tissue previously infected with resident bacteria. In the treatment at 100 atm, turbidity of the medium due to cell growth is observed, but not at 500 atm or more.
- the high pressure used here is in the range from 500 to 1500 atm, and research in the food field has already shown that sterilization is possible. It has also been reported that cell destruction and virus inactivation occur. However, there are no examples that have been comprehensively taken into consideration and proposed as a treatment method for transplantation. Considering all these factors, we have developed a new treatment method for biological tissue for transplantation by setting a condition range and a new treatment temperature range for each factor.
- a device such as a Kobe Steel Docsiff can be used.
- an ultra-high pressure experimental device manufactured by Kogaku Engineering Co., Ltd. can be used.
- a treatment system is installed in a small chamber, and a hydrostatic pressure of up to about 150,000 atmospheres can be applied using a liquid as a medium.
- the temperature in the chamber can be controlled by controlling the temperature in the outer jacket.
- the removal of cell nuclei is diffusion from the surface of the surfactant. Because of the permeation and permeation, it took a long time to remove cells deep in the tissue. Ultra-high pressure treatment can completely destroy and remove cells in the tissue in a short time of 30 minutes. Furthermore, it can be processed evenly to the inside of the cell debris.
- the efficiency of the washing process for removing cellular components can be dramatically increased.
- a significant reduction in antigenic causative substances can be achieved.
- Example Similar to the above, hard tissue processing such as bone, cartilage, and teeth can be performed.
- Example It can be used for cell destruction treatment of animal and plant-derived tissues that contain cells.
- a pig heart was purchased from an edible pig breeding ground and transported at 4 ° C.
- the warm ischemic time at the time of heart removal was set to 20 minutes or less.
- the pulmonary valve and blood vessel were removed and washed with Hank's solution.
- the donor cells were applied with a hydrostatic pressure of 37 ° (: 10 00 to 100 0 00 atmospheres) for 10 to 30 minutes using a doctor-made shaft manufactured by Kobe Steel.
- Treatment The tissue cross-section of the specimen was histologically evaluated by light microscopic observation with HE staining and EVG staining. The biomechanical characteristics of the heart valve leaf treated with high pressure were 3 mm wide and long.
- a strip of about 15 mm in length was cut out and subjected to a tensile test with a mechanical testing machine (Tensilon) to measure the tension until breakage. .
- the film thickness of the leaflets was obtained from the weight and specific gravity of the cut piece after measurement, and the elastic modulus was calculated from the stress strain characteristics.
- the infectivity of the tissue was evaluated by evaluating the bacterial growth ability by culturing the vascular tissue previously infected with resident bacteria after high-pressure treatment. As a result, as shown in Fig. 1, in the porcine pulmonary leaflet tissue decellularized by ultrahigh pressure treatment, the cells could be completely removed to the deep part of the tissue.
- the nucleus was not stained after 6 hours of immersion in the several hundred / m-thick leaflets, but the myocardium at the base of the leaflets The nuclei of cells in the tissue were stained at 1 mm or more from the surface even after 4 hours of treatment I.
- the biomechanical characteristics of the normal porcine pulmonary valve leaflets were about 1.05, which was almost equal to the vessel wall. Reference to the tangential direction of the vascular wall of the leaflet 0.
