Kidney tissue-derived stem cells or organoids according to the present invention are easy to apply for treatment, may be supplied in large amounts due to their high self-renewal capacity, have an excellent ability to differentiate into kidney cells, are less likely to form tumors, and have an excellent ability to regenerate damaged tissue when injected directly into lesions. Therefore, they may be used very suitably for regenerative therapy based on adult stem cells among these stem cells. In addition, a composition according to the present invention is capable of specifically selecting only kidney tissue-derived stem cells among kidney cells. Furthermore, kidney tissue-derived stem cells expressing Lrig1 protein or a gene encoding the same have excellent self-renewal and pluripotent abilities and are able to differentiate into nephrons, and thus they may be used very effectively for the prevention or treatment of kidney disease.

Isolated or purified mammalian kidney-derived cell populations from mammalian kidney tissue are provided. Methods are provided for the isolation and purification of the mammalian kidney-derived cell population. Methods for treating kidney disease are provided by administration of the isolated or purified mammalian kidney-derived cell population to a mammalian subject.

The disclosure describes novel systems, methods, and compositions for the manipulation of nucleic acids in a targeted fashion. The disclosure describes non-naturally occurring, engineered CRISPR systems, components, and methods for targeted modification of nucleic acids. Each system includes one or more protein components and one or more nucleic acid components that together target nucleic acids.

The invention relates to a method for the formation of renal tubules by embedding individual renal cells into a synthetic hydrogel, which is based on polyethylene glycol as a component, and the culturing of the cells until tubule structures are formed. The culturing can be continued until the obtained tubule structures correspond in terms of size, structure, morphology and functionality to adult human renal tubules or are at least similar thereto.

The present invention provides a method for culturing pluripotent stem cells, comprising the step of contacting pluripotent stem cells with laminin 421 or a fragment thereof, laminin 121 or a fragment thereof, or a combination thereof.

The present invention provides methods and kits for differentiating podocytes from pluripotent stem cells and from other cell types.

Methods and systems are provided for a stem cell organ device including an array of alternating stem cell channels and fluid channels. In one example, a method may include loading a stem cell channel with stem cells and flowing blood through a fluid channel in order to allow an exchange of molecules between the stem cells and the blood.

A method of generating one of podocyte progenitor cells and neural stem/progenitor cells comprising the steps of collecting a urine specimen from a patient; centrifuging the urine specimen; and removing the one of podocyte progenitor cells and neural stem/progenitor cells.

The embodiments of the present invention provide a method for the regeneration and differentiation of human perinephric fat derived mesenchymal stromal cells (hPNF-MSCs) into astroglial, renal, neuronal progenitor cells and pancreatic islet cells. The hPNF-MSCs are advantageous over bone marrow or other stem cell source due to the abundance and ease of isolation. The perinephric fat derived stromal cells are used in the treatment of neurodegenerative disorder, renal disorder and pancreatic malfunction. The method for the regeneration and differentiation of hPNF-MSCs includes isolation of the human perinephric fat derived stromal cells followed by expansion of the stem cells and cryopreservation. The cells are characterized by morphological evaluation of hPNF-MSC, growth kinetics, immunophenotypic evaluation, differentiation potential analysis, karyotyping and secretome profiling (cytokines, chemokines, and growth factors). The stem cells are differentiated into astroglial cells, neural cells renal cells and pancreatic islet cells.

The present invention provides methods and kits for differentiating podocytes from pluripotent stem cells and from other cell types.
