Novel MSC stem-cell culture and therapy methods and culture medium compositions for the purpose of inducing, activating, or priming discrete uniform cell phenotypes to selectively promote or suppress inflammation and immunity, yielding polarized, primed, activated, or induced cells used in cell-based therapy.

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.

Methods and compositions for modifying glycans (e.g., glycans expressed on the surface of live cells or cell particles) are provided herein.

Novel MSC stem-cell culture and therapy methods and culture medium compositions for the purpose of inducing, activating, or priming discrete uniform cell phenotypes to selectively promote or suppress inflammation and immunity, yielding polarized, primed, activated, or induced cells used in cell-based therapy.

Methods of treating an adult mammal for an aging-associated impairment are provided. Aspects of the methods include reducing cell surface VCAM-1 activity in the mammal in a manner sufficient to treat the mammal for the aging-associated impairment. A variety of aging-associated impairments may be treated by practice of the methods, which impairments include cognitive impairments.

Provided is an application of an ICAM-1 marker and a regulating agent thereof in promoting or inhibiting differentiation of adipose-derived stem cells into adipose cells, and an application of ICAM-1 or detection reagent thereof in (a) detecting adipose-derived stem cells, and/or (b) determining the risk of a subject suffering from obesity and a corresponding diagnostic kit and method. Further provided is an in vitro non-therapeutic preparation method for fat cells.

The present invention relates to methods that are based on expression of integrin alpha10 and integrin alpha11 on chondrocytes, used for determining purity, quality, degree of chondrocytic identity, chondrocytic potency, and/or degree of chondrocytic phenotype of a composition comprising chondrocytes, as well as for isolating and enriching a population of high quality chondrocytes and controlling culturing and expanding of high quality chondrocytes. The present invention relates also to composition comprising chondrocytes.

Described are methods and devices for enrichment and in situ expansion of circulating tumor cells (CTCs) from biological samples. The methods may include detecting at least one or more of cell adhesion molecules as epithelial mesenchymal transition (EMT) biomarker. Also described is device for detecting or enriching CTCs. The surface of the device may provide at least one or more of cell binding ligands such as ECM or cadherin derived peptide motif to detect the EMT biomarker. Also described is a surface to remove leukocytes from biological samples, leading to efficient enrichment of CTCs from the biological samples.

The disclosure provides a method of delivering a polypeptide molecule to an Otx2 target cell, including contacting the target cell with a chimeric polypeptide having (i) a targeting peptide consisting of SEQ ID NO: 2 and (ii) the polypeptide molecule.

Disclosed herein are methods of producing pancreatic hormone-expressing cells by first differentiating pluripotent cells in cell culture so as to produce endodermal cells, the endodermal cells being competent to further differentiate into hormone-expressing cells capable of secreting at least one pancreatic hormone in response to a physiological signal, and then, transplanting the cultured endodermal cells into an organism, such as an organism in need of an endocrine cell therapy.
