According to the present disclosure, there is provided a method for culturing factor-introduced cells, the method including culturing factor-introduced cells and recovering the factor-introduced cells and seeding at least part of the recovered cells in a medium for seeding. In addition, there is provided a method for culturing factor-introduced cells, the method including culturing factor-introduced cells and inducing the factor-introduced cells to somatic cells different from pluripotent stem cells without passaging.

The invention provides methods for reprogramming somatic cells to generate multipotent or pluripotent cells. Such methods are useful for a variety of purposes, including treating or preventing a medical condition in an individual. The invention further provides methods for identifying an agent that reprograms somatic cells to a less differentiated state.

Compositions and methods are provided for reprogramming dermal fibroblasts to exhibit vasculogenic properties including the ability to stimulate vasculogenesis in vivo. In accordance with one embodiment such compositions are used in conjunction with standard treatment for use on chronic wounds including in diabetic patients.

A method of producing induced pluripotent stem cells without using a hydrogel.

The invention generally features compositions comprising induced pluripotent stem cell progenitors (also termed reprogramming progenitor cells) and methods of isolating such cells. The invention also provides compositions comprising induced pluripotent stem cells (iPSCs) derived from such progenitor cells. Induced pluripotent stem cell progenitors generate iPSCs at high efficiency.

The disclosure includes embodiments for utilizing fibroblasts derived from cancer patients and generating “de novo” tumor specific cancer cells and cancer stem cells. The cells may be used as a source of one or more patient-specific antigens for generating one or more personalized tumor vaccines.

This disclosure relates to using a ETV2 gene or gene products including DNA, RNA, mRNA, ETV2 proteins, or protein containing exosomes, to directly reprogram and convert resident non-endothelial cells of host into endothelial cells in situ, i.e., in places of the body or tissue where ETV2 is injected. In certain embodiments, it is contemplated that directly reprogrammed and converted endothelial cells will enhance blood vessel regeneration in the tissues where blood vessels have been damaged.

Compositions and methods are provided for reprogramming demal fibroblasts to exhibit neurogenic properties including increased cell expression of NGF and Nt3 in vivo. In accordance with one embodiment such compositions are used in conjunction with standard treatment for use in treating neuropathic pain and stabilizing or stimulating production of PGP9.5+ mature nerve fiber in a diabetic patient’s tissues.

A method of generating protein-induced pluripotent stem cells by delivering bacterially expressed reprogramming proteins into nuclei of starting somatic cells using the QQ-protein transduction technique, repeating several cell reprogramming cycles for creating reprogrammed protein-induced pluripotent stem cells, moving the reprogrammed cells into a feeder-free medium for expansion, and expanding and passaging the reprogrammed cells in a whole dish for generating homogeneous piPS cells. Also provided are the piPCS cells formed using this method and uses thereof.

An object of the present invention is to provide a pluripotent cell having high safety in application to regenerative medicine, and a method for production thereof. Another object of the present invention is to provide a pluripotent cell, particularly, having less concern for safety, such as a problem of cancerization of a cell, and the presence of bacteria in a cell, and a method for production thereof. According to the present invention, there is provided a method for producing a pluripotent cell from a somatic cell. The method comprises a step of inducing reprogramming of a somatic cell, by contacting the cell with a ribosome fraction derived from an organism. Further, according to the present invention, there is provided a composition for inducing reprogramming of a cell, comprising a ribosome fraction derived from an organism.
