Abstract:
The current disclosure provides methods for reprogramming mammalian somatic cells by regulating the expression of endogenous cellular genes. Cellular reprogramming of somatic cells can be induced by activating the transcription of embryonic stem cell-associated genes (e.g., oct.3/4 ) and suppressing the transcription of somatic cell-specific and/or cell death-associated genes. The endogenous transcription machinery can be modulated using synthetic transcription factors (activators and suppressors), to allow for faster, and more efficient nuclear reprogramming under conditions amenable for clinical and commercial applications. The current disclosure further provides cells obtained from such methods, along with therapeutic methods for using such cells for the treatment of diseases amendable to stem cell therapy, as well as kits for such uses.

Abstract:
Described herein are methods for enhancing the nuclear reprogramming of somatic cells to become induced pluripotent stem cells. In particular, the methods disclosed herein involve the use of damage-associated molecular pattern molecules (DAMP). In certain embodiments the DAMPs are aluminum compositions such as aluminum hydroxide. Such DAMPs have unexpectedly and surprisingly been found to enhance the nuclear reprogramming efficiency of the reprogramming factors commonly used to induce somatic cells to become induced pluripotent stem cells. Accordingly, this disclosure describes methods of nuclear reprogramming as well as cells obtained from such methods along with therapeutic methods for using such cells for the treatment of disease amendable to treatment by stem cell therapy; as well as kits for such uses.
Abstract:
Provided herein are compositions, methods, and kits for hematopoietic stem cell induction or for reprogramming cells to the multipotent state of hematopoietic stem cells. In some embodiments, the compositions comprise at least one HSC inducing factor. Such compositions, methods and kits can be used for inducing hematopoietic stem cells in vitro, ex vivo, or in vivo, as described herein, and these induced hematopoietic stem cells can be used in regenerative medicine applications and therapies.
Abstract:
Provided herein are methods of producing natural killer (NK) cells and NK progenitor cell populations using a two-step expansion and differentiation method. Also provided herein are methods of producing populations of NK cells and NK progenitor cell populations using a three-step expansion and differentiation method. Also provided herein are methods of suppressing tumor cell proliferation using the NK cells, the NK cell populations, and the NK progenitor cell populations produced by the methods described herein, as well as methods of treating individuals having cancer or a viral infection, comprising administering the NK cells, the NK cell populations, and the NK progenitor cell populations produced by the methods described herein to an individual having the cancer or viral infection.
Abstract:
The present invention provides methods and compositions for converting a T cell into a cell that exhibits at least one regulatory T cell phenotype. The converted T cell is generated by contacting a T cell with a cell that is modified to comprise an agent capable of activating PD1 signaling in a T cell. The converted T cell is useful for preventing, suppressing, blocking or inhibiting an immune response. For example the converted T cell is useful for preventing rejection of a transplanted tissue in a human or other animal host, or protecting against graft versus host disease. The converted T cell can also be used to treat autoimmune diseases.
Abstract:
This invention concerns anti-inflammatory agents and methods for treating inflammatory disorders. Also disclosed are methods for identifying or evaluating anti-inflammatory agents or compositions.
Abstract:
Hematopoietic stem cells (HSCs) are programmed to generate induced pluripotent stem cells (iPSCs) that express anti-HIV polynucleotides including a CCR5 shRNA and a human/rhesus chimeric TRIM5? gene and optionally a Tar decoy. Upon directed differentiation of the anti-HIV iPSCs towards the hematopoietic lineage, colonies forming CD133+ HSCs were obtained. These cells were further differentiated into functional end stage macrophages which displayed a normal phenotypic profile. Upon viral challenge in vitro and in vivo, the anti-HIV iPSC derived macrophages exhibited strong protection from HIV-1 infection and can be used for the prevention or treatment of HIV infection in patients.
