Disclosed are means of suppressing production of the inflammatory cytokine TNF-alpha through contact-dependent and contact-independent means by fibroblast populations and products and/or derivatives of fibroblast populations. In one embodiment, fibroblasts are cultured under conditions allowing proliferation of said fibroblasts, wherein said proliferative status of fibroblasts correlates with the ability to directly suppress TNF-alpha production, and/or to release one or more factors capable of suppressing TNF-alpha production. In one embodiment, fibroblasts are used for treatment of inflammatory diseases by their ability to suppress TNF-alpha production. In other embodiments, conditioned media and/or exosomes of said fibroblasts are utilized to treat inflammatory diseases by their ability to suppress TNF-alpha production.

The present disclosure relates to methods for increasing telomere length in one or more human cells and/or increasing genome stability of one or more human cells, for example by contacting one or more human cells with an agent that increases expression of Zscan4 in the one or more human cells. Methods of treating a subject in need of telomere lengthening, treating a disease or condition associated with a genomic and/or chromosome abnormality, of rejuvenating one or more human cells, of rejuvenating tissues or organs, and of rejuvenating a subject in need thereof, for example by contacting one or more human cells in the subject with an agent that increases expression of Zscan4, or by administering to a subject in need thereof, an agent that increases expression of Zscan4 are also provided.

Compositions comprising donor cells, acceptor cells, membrane-enclosed bodies and methods are described herein.

Embodiments herein relate to in vitro production methods of hematopoietic stem cell (HSC) and hematopoietic stem and progenitor cell (HSPC) that have long-term multilineage hematopoiesis potentials upon in vivo engraftment. The HSC and HSPCs are derived from pluripotent stem cells-derived hemogenic endothelia cells (HE) by non-integrative episomal vectors-based gene transfer.

Disclosed are means of enhancing therapeutic effects of fibroblast administration through utilization of extracorporeal shock waves. In one embodiment, enhancement of intravenously administered fibroblast therapeutic activity is accomplished by introducing extracorporeal shock waves to the patient in need of therapy. In one specific embodiment, enhancement of the ability of fibroblasts administered intravenously to treat a condition is accomplished by exposure of areas areas affected by the condition to extracorporeal shock waves. In another specific embodiment, the invention provides transfection of IL-12 and/or IL-23 into fibroblasts to augment regenerative activity, including neuroregenerative and anticancer activity. In further embodiments the invention provides augmentation of regenerative activity by induction of T regulatory cells utilizing IL-35 transfection, wherein said T regulatory cells provide an optimized environment for stimulation of regenerative activity.
