    Abstract: Compositions of matter and treatment protocols for reducing or completely avoiding the need for immune suppression in the context of allograft or xenograft transplantation. Use of mesenchymal stem cells, manipulated mesenchymal stem cells, iPSC derived mesenchymal stem cells, and products of said mesenchymal stem cells for promoting the process of immunological tolerance. In one embodiment the invention provides the use of third party “universal donor” iPSC gene edited mesenchymal stem cells to promote tolerance in context of a solid organ transplant such as renal, cardiac, hepatic or small intestine. In other embodiments endogenous mesenchymal stem cells in composite tissue allografts are activated and/expanded in order to promote tolerogenesis and reduced need for immune suppression.

    Abstract: Methods and compositions of matter useful for reducing extent of spinal cord injury and/or reversion of spinal cord injury gliosis are disclosed. T regulatory cells can be administered systemically and/or locally to a patient suffering from spinal cord injury. T regulatory cells can be modulated by engineering either through gene modification or culture conditions in order to augment regenerative/antifibrotic properties. Utilizing pluripotent stem cell derived T regulatory cells for spinal cord injury and chimeric antigen receptor T cells.

    Abstract: The invention provides methods of inducing immunological tolerance to a transplanted cellular population or organ by creating and administering a “veto-like” cell originating from the identical genetic background of the organ donor. In one embodiment said artificially generated veto cell is a dendritic cell population possessing molecules associated with tolerance induced in natural anatomical locations such as the placenta, the testis, or the eye. In one embodiment dendritic cells resistant to maturation are generated from pluripotent stem cells that have been gene edited to lack genes needed for acquisition of antigen presenting properties such as relB, NF-kappa B and transporter associated protein. In another embodiment immature dendritic cells are gene edited/transfected to express tolerance associated molecules such as interleukin-10, interleukin-35, Fas ligand, TRAIL, TGF-beta, HLA-G and arginase.

    Abstract: Disclosed are systems, means and compositions of matter utilizing artificial intelligence to create unique cells and/or organs from pluripotent stem cells. In one embodiment an artificial intelligence/machine learning approach is utilized to overview and categorize molecular and cellular data regarding normal embryonic development and associated pathways. Through acquiring this information, said artificial intelligence/machine learning system develops a graded list of morphogens/differentiating agents and/or conditions that are utilized to replicate the process of cell/tissue/organ formation artificially. In one embodiment the invention teaches generation of artificial pancreatic organoids through growth factors predicted by said artificial intelligence/machine learning systems. In other embodiments embryogenesis is recapitulated in adult tissue using predicted morphogens and/or extracellular matrix treatments.

    Abstract: Disclosed are compositions of matter, protocols, and procedures useful for generation of mesenchymal stem cells capable of withstanding the microenvironment of degenerating ovaries. In one embodiment mesenchymal stem cells are pre-treated under conditions capable of upregulating cytoprotective responses and genes, such as HIF-1 alpha and hemoxygenase. In other embodiments mesenchymal stem cells are temporarily pulsed with hypoxia and/or acidity in order to prime them for the harsh environment of degenerating ovarian tissue. Through this approach increased viability of mesenchymal stem cell subsequent to intra-ovarian administration is achieved.
