    摘要: The invention discloses means of treating lung degenerative diseases including chronic obstructive pulmonary disease (CODP) using umbilical cord mesenchymal stem cells such as JadiCells alone, and/or using said cells under conditions that are activated in order to endow enhanced regenerative activity. In one embodiment said activation of said mesenchymal stem cells is performed through stimulation with a toll like receptor agonist at a concentration and duration sufficient to induce a >50% increase in keratinocyte growth factor expression from said stem cells. In another embodiment the invention provides the use of JadiCells as a means of producing exosomes, wherein said exosomes possess therapeutic properties capable of reducing inflammation, fibrosis and degeneration associated with COPD, as well as stimulation of regenerative activity. In some JadiCells are activated by a treatment with Activated Protein C.

    摘要: Disclosed are novel means, protocols, and compositions of matter for creating targeted immune responses and/or induction of immunological memory towards the tumor vasculature. In one embodiment pluripotent stem cells are transfected with one or more genes capable of eliciting immunity, induced to differentiate into endothelial-like cells which resemble the tumor endothelial cells, and utilized as a vaccine. In some embodiment's 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 (Galα1,3Galα1,4GlcNAc-R). Addition of adjuvants to enhance antigen presentation of the vaccine composition, as well as means of stimulating systemic enhancement of circulating endothelial specific T cells are also disclosed.
