ORGAN REGENERATION METHOD UTILIZING BLASTOCYST COMPLEMENTATION

An object of the present invention is to produce a mammalian organ having a complicated cellular composition composed of multiple kinds of cells, such as kidney, pancreas, thymus and hair, in the living body of a non-human animal. The inventors of the present invention applied the chimeric animal assay described above, to a novel solid organ production method. More specifically, the inventors has shown that a model mouse which is deficient of kidney, pancreas, thymus or hair due to the dysfunction of the metanephric mesenchyme that is differentiated into most of an adult kidney, is rescued by blastocyst complementation by the chimeric animal assay, and whereby a kidney, a pancreas, thymus or hair can be newly produced.

ENGINEERED CARTILAGE

It is provided a method of producing high-quality engineered cartilage graft in a human of animal, such as nasal cartilage graft, comprising expanding chondrocytes and/or chondroprogenitors, e.g. autologous human nasoseptal chondrocytes (hNC,) from a donor patient by selecting expanded chondrocytes and/or chondroprogenitors by detecting the expression of at least one surfaceome protein gene or secretome protein gene, wherein the at least one surfaceome protein gene is ADGRG1, NPR3, SLC16A4, TSPAN13, FZD4 and SLC22A23 and the at least one secretome protein gene is ADGRG1, B3GNT7, COLGALT2, IGFBP3, STC2, SAA1, ANGPLT1, COL8A2, INHBB, ADAMTS9, ORM1, COL14A1, DCN, COL21A1, ENOX1, IL7, MXRA5 GAL, TFRC, SERPINA9, LIF, GDF6 and COL5A3.

INJECTABLE IN SITU PORE-FORMING HYDROGEL SYSTEM AND PREPARATION METHOD AND USE THEREOF

An injectable in situ pore-forming hydrogel system and its preparation method and use are provided. The injectable in situ pore-forming hydrogel system uses an injectable hydrogel as a continuous base phase, and isolated live cells and magnesium particles are distributed in the continuous base phase, where the injectable hydrogel is a precursor or prepolymer of hydrogel, which can form hydrogel by cross-linking. The injectable in situ pore-forming hydrogel system can be used to create pores while the gel encapsulates live cells, which makes use of both the injectability and porous structures of hydrogel, which is important for the repair of cavitary, surgically difficult and irregularly defective tissues; meanwhile, magnesium particles generate magnesium ions after the former undergoes gas production and degradation, which can improve the bioactivity of the gel and aid in tissue repair.

METHOD FOR FABRICATION OF EXTRACELLULAR MATRIX-INDUCED SELF-ASSEMBLY AND FABRICATION OF ARTIFICIAL TISSUE USING SAME

The present invention relates to a method for fabrication of an extracellular matrix-induced self-assembly and to fabrication of an artificial tissue using same. The method for fabrication of an extracellular matrix-induced self-assembly comprise the steps of: (a) decellularizing and powdering a tissue-derived extracellular matrix (ECM); and (b) adding the decellularized extracellular matrix powder to cells and culturing the cells to form a cell-extracellular matrix powder self-assembly. Accordingly, the self-assembly has characteristics similar to those of extracellular matrix tissues and can be fabricated into three-dimensional artificial tissues 1 cm or greater in size, thus finding advantageous applications as a cell therapy product and an artificial tissue implant.

Method for preparing of nerve conduit using bio-printing technology and the nerve conduit prepared by the same

The present invention relates to a method for preparing of a nerve conduit using bio-printing technology and a nerve conduit prepared by the same, and it can easily prepare a nerve conduit by simulating a nerve bundle and nerve tissue, and the like, by three-dimensionally printing bio-ink comprising a neuronal regeneration material on one side of a porous polymer scaffold.

BONE FRAGMENT AND TISSUE PROCESSING SYSTEM
20230079824 · 2023-03-16 ·

A tissue collection and processing system for collecting bone fragments and tissue aspirated from a bone. The tissue collection and processing system includes a collection vessel, a collection vessel cap, a processing cover, a first tubing and a fluid withdrawal mechanism. The collection vessel has an opening formed therein to receive bone fragments and tissue aspirated from the bone. The collection vessel cap is capable of engaging the collection vessel to substantially seal the opening. The collection vessel cap or the collection vessel has a first port. The processing cover has an upper surface and a lower surface. The processing cover has a connection port and a bore. The connection port is proximate the upper surface. The bore is fluidly connected to the connection port and extends toward the lower surface. The processing cover has a density that is less than a density of fluid in the aspirated bone fragments and tissue. The fluid withdrawal mechanism is fluidly connected to the connection port with the first tubing to withdraw the fluid from the collection vessel. As fluid is withdrawn from the collection vessel, the processing cover is slidable in the collection vessel.
