Disclosed herein are methods of treating a disorder in a patient by administering immune evading cells. In some embodiments, the patient receives more than one administration of such cells. In some embodiments, the cells disclosed herein have reduced levels or activities of MHC I and/or MHC II human leukocyte antigens. In some embodiments, the cells are derived from primary T cells or pluripotent stem cells that evade immune recognition. In some embodiments, the cells comprise a chimeric antigen receptor.

Described herein are methods for treating, repairing or ameliorating diseases, disorders, or injuries related to dry eye, osteoarthritis, tendon, ligament, bone repair, wound healing or wound-healing related disorders, alopecia or in skin rejuvenation or regeneration with platelet-like-cells or variants thereof (PLCs) or derivatives thereof or lysates thereof or the platelet rich plasma (PRP) derived therefrom. Also, described herein are methods for generating platelet rich plasma (PRP) from the PLCs or derivatives thereof or lysates thereof.

Provided is an isolated population of human pluripotent stem cells comprising at least 50% human pluripotent stem cells characterized by an OCT4+/TRA1-60−/TRA1-81−/SSEA1+/SSEA4− expression signature, and novel methods of generating and maintaining same in a pluripotent, undifferentiated state a suspension culture devoid of cell clumps. Also provided are novel culture media, cell cultures and methods for culturing pluripotent stem cells in a suspension culture or a two-dimensional culture system while maintaining the cells in a proliferative, pluripotent and undifferentiated state. The novel culture media comprise interleukin 11 (IL11) and Ciliary Neurotrophic Factor (CNTF); bFGF at a concentration of at least 50 ng/ml and an IL6RIL6 chimera; or an animal contaminant-free serum replacement and an IL6RIL6 chimera. Also provided are methods for generating lineage-specific cells from the pluripotent stem cells.

The present invention relates to the field of biology and medicine, and more specifically, to the field of stem-cell biology, involving producing or generating melanocytes from stem-cells and precursors derived from human hair root. Additionally, the present invention relates to the materials and method for producing autografts, homografts or allografts comprising melanocytes in general, as well as the materials and methods for producing autografts, homografts and allografts comprising melanocytes for the treatment of diseases related to depigmentation of the skin and for the treatment of scars.

The present invention provides a method for generation of a cell composition of mesencephalic dopaminergic progenitor cells from a starting cell composition comprising pluripotent and/or multipotent stem cells, the method comprising the steps of a) differentiating said pluripotent and/or multipotent stem cells into mesencephalic dopaminergic progenitor cells, thereby generating a cell population comprising mesencephalic dopaminergic progenitor cells and other cells, b) dissociating the differentiated cells of step a) into a single cell suspension, and c) enriching said mesencephalic dopaminergic progenitor cells by using an antigen binding molecule specific for the CD47 antigen for positive selection of said mesencephalic dopaminergic progenitor cells in said single cell suspension. Said method may be performed in a closed cell sample processing system and may be performed in an automated manner.

The present invention provides cell populations that are enriched for mesendoderm and mesoderm, and cell populations that are enriched for endoderm. The cell populations of the invention are useful for generating cells for cell replacement therapy. The present invention further provides a method of generating hepatocytes, cell populations enriched for hepatocytes, and a method of hepatocyte replacement therapy.

Provided herein are methods of enriching a retinal pigment epithelium (RPE) cell population derived from stem cells. Such a method may comprise removing contaminating cells through the depletion of CD24 positive cells, CD56 positive cells, and/or CD90 positive cells from a starting population of RPE cells.

The invention provides an isolated limbal stem or progenitor cell (LSC) population or LSC-like population comprising a chemically synthesized, recombinant or isolated nucleic acid encoding PAX6 integrated into a chromosome, or alternatively, not integrated remaining as an extrachromosomal genetic material, wherein the isolated LSC population is substantially free of non-LSC cells or wherein the LSC-like population is substantially free of non-LSC-like cells, or wherein the isolated LSC or LSC-like population is substantially free of non-LSC and non-LSC-like cells and uses thereof.

The present disclosure provides highly efficient, non-invasive, and reversible methods for selectively enriching pluripotent cells (e.g., human pluripotent cells and mouse pluripotent cells) in a cell population using a glutamine-deficient medium. The presently disclosed methods have the advantageous of efficiently enriching pluripotent cells in a heterogenous cell population without altering the biological properties of any individual cells.

The present invention provides an isolated population of chondrocyte precursor cells wherein 1% or less of the cells express Oct4, Nanog and/or TRA-1-60, 7% or less of the cells express no collagen II, collagen X, CD105 or Stro-1 and 85% or more of the cells express CBFA1, methods for preparing such cells and uses of chondrocyte cells derived from said precursor cells.
