The present invention provides the new use of composition comprising at least one inhibitor of dipeptidyl peptidase IV (DPP-IV) for increasing migration and homing of haematopoetic progenitor cells in stem cell transplanted recipients, wherein said haematopoetic stem and/or progenitor cells had been treated in vitro with an engraftment enhancing compound, specifically with a prostacyclin analogue and a cAMP enhancer before transplantation.

A method of producing induced exosomes, the method comprising: contacting an isolated population of stem cells with an amount of a prostaglandin E receptor 4 (EP4) antagonist effective for inducing release of exosomes, whereby induced exosomes are released from the stem cells, and isolating the induced exosomes.

The present invention is directed to compositions and methods to increase the expression of PD-L1 and/or IDO-1 in a population of cells, the modulated cells expressing increased PD-L1 and/or IDO-1, and methods related to the immunosuppressive effects obtained by cells expressing increased PD-L1 and/or IDO-1.

The present invention provides universal donor cellular populations derived from umbilical cords possessing ability to elicit immune modulation and evoke regeneration when administered into a mammalian host. Generation of cellular products for clinical use are provided including methodologies of expansion, characterization, and means of therapeutic implementation.

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).

Provided herein are methods for preparing hematopoietic stem cells (HSCs) having enhanced engraftment activity, for example, by contacting HSCs in the presence of a p38 MAPK inhibitor and a HIF-1a stabilizer.

Embodiments of the disclosure concern methods and compositions for immunotherapy for human papillomavirus infection and diseases associated therewith. In specific embodiments, methods concern production of immune cells that target one or more antigens of HPV16 and/or HPV18, including methods with stimulation steps that employ IL-7 and IL-15, but not IL-6 and/or IL-12. Other specific embodiments utilize stimulations in the presence of certain cells, such as costimulatory cells and certain antigen presenting cells.

Provided are methods for treating or preventing vasculopathy comprising administering to a subject in need thereof , ac composition comprising a mesenchymal stem cell (MSC), or a part of a culture medium that has been in contact with the MSC and comprises one or more components of the MSC, or an exosome derived from the MSC. Pharmaceutical compositions suitable for such treatment is also provided.

The present invention provides methods of inducing proliferation of and/or differentiating cells comprising contacting cells with compounds within the methods of the invention. The present invention further provides cells obtainable by the methods of the invention.

The present invention relates to an in vitro culture of haematopoietic cells, wherein said haematopoietic cells differentiate to form granulocytes characterised by the ability to kill cancer cells. The invention also relates to said granulocytes, methods for identifying said haematopoietic cells and granulocytes, compositions and kits comprising the same, as well as uses of the same for treating cancer.
