摘要:
The types and relative proportions of cells constituting a cell sheet stack, and the number of cells to be seeded are altered to change the state of the cells in the cell sheet stack, whereby production of an angiogenesis-promoting cytokine as well as construction of a vascular endothelial network can be optimized.
摘要:
To provide an oxygen-absorbing polyester resin composition which exhibits excellent oxygen-absorbing capability even in the absence of transition metal catalyst without affected by the glass transition temperature of a polyester resin that is contained as a base resin.The oxygen-absorbing polyester resin composition including a base resin (A) which is a polyester resin, an oxygen-absorbing component (B) which is a compound having an unsaturated alicyclic structure, and an oxidation promotion component (C) for promoting the oxidation of the oxygen-absorbing component (B), said oxidation promotion component (C) being a compound having a benzyl hydrogen.
摘要:
The present invention aims to provide an artificial tissue that can efficiently reproduce myocardial tissue function and that can be used in an actual implantation and produced by culturing. The present invention relates to a graft material for treating myocardial disease, the graft material including a cell sheet containing adipocytes.
摘要:
Three-dimensional information on a biological parameter relating to at least one selected from viability, proliferating ability, migration, and differentiation of cultured cells can be obtained by a simple two-dimensional analytical technique by constructing a cell evaluation system including a multilayered cell sheet, target cells, and a two-dimensional analyzer.
摘要:
The present invention provides a method of treatment for ischemic heart disease administering a scar formation accelerator containing at least one selected from SFRP2, SFRP4, Midkine, Pleiotrophin and Thymosin beta-10 as an effective ingredient to promote scar formation less fibrosis and retaining elasticity, and thereby improving cardiac function.
摘要:
It is a purpose to provide a medicinal-liquid injection apparatus in which a needle-like tubular member is smoothly movable in a lumen without damaging an inner circumferential surface of the lumen. It includes that the needle-like tubular member having an acuminate needle portion as a free end portion thereof, in which a medicinal liquid can flow, is inserted in the lumen of a tubular main body insertable in a body of a living being, and a protection member having a flexible portion provided in a state such that the protection member is movable together with the needle-like tubular member and such that the flexible portion is interposed between an inner circumferential surface of the lumen and a tip of the needle portion of the needle-like tubular member.
摘要:
A method for injecting a liquid drug containing a biological material is provided, which comprises the step of injecting the liquid drug containing the biological material contained in an injector into a subject at a predetermined range of velocity.
摘要:
An objective of the present invention is to overcome a problem that there is an inverse relationship between the decellularization rate and the strength of tissue. This problem was solved by immersing tissue in a solution containing a non-micellar amphipathic molecule (e.g., a 1,2-epoxide polymer). Thus, the present invention provides decellularized tissue, in which the cell survival rate of the tissue is less than a level at which calcification or an immune reaction is elicited in an organism and the tissue damage rate of the tissue is suppressed to a level which permits clinical applications. Tissue prepared by the above-described treatment preferably retains a certain level of tissue strength. Further, the tissue of the present invention has an effect of performing cell replacement.

摘要:
To provide a new reductive-stimuli-responsive degradable gel that allows any control of decomposition of the three-dimensional base material for cell culture and production of a completely biological three-dimensional cellular structure consisting only of cells and cells-produced extracellular matrix and that allows safe recovery of the cellular structure produced. A stimuli-responsive hydrogel, characterized by being produced by crosslinking a water-soluble polymer with a compound having a disulfide bond in the molecular chain.
