Certain exemplary embodiments are directed to a biologically active composition of matter (and uses thereof) configured for targeted delivery of biotin to mitochondria, the composition comprising a first D-biotin conjugated to a water-soluble, cell-permeable, peptide sequence, wherein the peptide sequence is selected from a polypeptide group with an alternating aromatic-cationic motif.

A method for scarless genome editing is disclosed. In particular, the method provides scarless genome modification by using homology directed repair (HDR) steps to genetically modify cells and remove unwanted sequences. This method can be used for genome editing, including introducing mutations, deletions, or insertions at any position in the genome without leaving silent mutations, selection marker sequences, or other additional undesired sequences in the genome.

Provided is a method for freezing a cell aggregate including neural cells. Provided is a method for freezing a cell aggregate including neural cells and having a three-dimensional structure, which comprises following steps (1) and (2): (1) soaking the cell aggregate including neural cells in a cryopreservation solution at 0° C. to 30° C. prior to freezing to prepare a cryopreservation solution-soaked cell aggregate; and (2) freezing the cell aggregate including neural cells in vapor phase of a liquid nitrogen container having a temperature of −150° C. or less.

Methods, compositions and cells are provided that identify and isolate a population of adult non-embryonic progenitor cells having multilineage potential, physical diameters of about 2 μm to about 8 μm in size or about 4 μm to about 6 μm, and expressing at least one of the stem cell associated genes among Oct-4, KLF-4, Nanog, Sox-2, Rex-1, GDF-3 or Stella. Methods are also provided that identify and isolate populations, which are subsets or subpopulations of progenitor adult stem cells within the population of the adult stem cells which is a heterogeneous population, the methods including contacting the adult stem cells with a ligand specific for at least one of: CD99, tetraspan, ICAM4, full-length MUC1, and truncated MUC1 receptor, in which a presence of a surface protein on the cells that bind to the ligand identifies the population which is the subset of the differentiated progenitor adult stem cells.

The present invention provides methods and compostions to improve the efficiency of somatic cell nuclear transfer (SCNT). There is increasing evidence that the epigenetic state of donor nuclei has a significant impact on potential of nuclear transfer embryos to develop into blastocysts, from which pluripotent stem cells are derived. Strategic application of histone agents, capable of altering epigenetic state such as methylation, allows zygotic activation and robust blastocyst generation.

Disclosed are novel means, protocols, and compositions of matter for eliciting an immune response against blood vessels supplying neoplastic tissue. In one embodiment pluripotent stem cells are transfected with one or more genes capable of eliciting immunity. In some embodiments such genes are engineered under control of specific promoters to allow for various specificities of activity. In one specific embodiment pluripotent stem cells engineered to endow properties capable of inducing expression of the α-Gal epitope (Galα1,3Galα1,4G1cNAc-R).

Compositions and methods for generating insulin-producing beta cells from pluripotent stem cells are provided. The compositions and methods of the present invention involve stepwise differentiation while the differentiating cells are cultured on a lung tissue-derived acellular scaffold.

An object is to provide a cell product for treating and/or preventing vascular dementia. The present invention provides a cell product for treating or preventing vascular dementia, containing a SSEA-3-positive pluripotent stem cell (Muse cell) derived from a mesenchymal tissue in a living body or a SSEA-3-positive pluripotent stem cell derived from a cultured mesenchymal cell.

A method of treating medical conditions by stem cell therapy. Stem cells are transplanted into and onto a human or animal patient in need, Then stem cell proliferation is increased, activating migration to sites of inflammation and epigenetic effects, regenerating damaged tissues through inhibition of apoptosis, inhibition of inflammation and oxidative stress, and inducing angiogenesis and stem cell differentiation into various cells by administering substances that induce GSK-3 beta inhibition and HDAC inhibition.

The present specification provides: a method of isolation of a pure culture of vascular endothelial cells, the method capable of isolating homogeneous endothelial cells adhered to a matrix for a specific time in a cell line of an endothelial cell lineage differentiated from human pluripotent stem cells; a medium for maintaining characteristics of vascular endothelial cells, comprising high-purity vascular endothelial cells isolated through the method, 4 ng/ml to 6 ng/ml of FGF2, 5 ng/ml to 10 ng/ml of EGF, 10 ng/ml to 30 ng/ml of VEGF-A, 20 ng/ml to 50 ng/ml of ascorbic acid, and DMEM/F-12 as active ingredients; and a culture method comprising same.
