  • Publication number: 20090214492
    Abstract: Methods of treating a human patient having a disease, disorder or condition of the central nervous system are disclosed. The methods include obtaining a bone marrow sample from a human donor, isolating stromal cells from the bone marrow sample, and administering the isolated stromal cells to the central nervous system of the human patient, wherein the presence of the isolated stromal cells in the brain effects treatment of the disease, disorder or condition. Stromal cells which are isolated may be cultured in vitro, they may be genetically engineered to produce therapeutic compounds, and/or they may be pre-differentiated prior to administration into the central nervous system.

  • Patent number: 7547545
    Abstract: The invention relates to methods for inducing marrow stromal cells to differentiate into neural cells by way of increasing intracellular levels of cyclic AMP. The invention also encompasses methods of producing a neural cell by causing a marrow stromal cell to differentiate into a neural cell by increasing intracellular levels of cyclic AMP. Methods for treating a human patient in need of neural cells are also disclosed, as well as methods for treating a human patient having a disease, condition, or disorder of the central nervous system.

  • Publication number: 20080299097
    Abstract: Multipotent stromal cells “MSCs” have been described as consisting of at least two populations of cells, rapidly self-renewing stem cells (RS-MSCs), and larger, slowly replicating cells (mMSCs). The present invention provides methods for enhancing engraftment of MSCs in vivo by administering an enriched fraction of RS-MSCs that express certain cell surface markers.

  • Publication number: 20080131407
    Abstract: The present invention relates to methods of inducing differentiation of mammalian bone marrow stromal cells into neuronal cells by contacting marrow stromal cells with a neuronal differentiation-inducing compounds. Neuronal differentiation-inducing compounds of the invention include anti-oxidants such as, but not limited to, beta-mercaptoethanol, dimethylsulfoxide, butylated hydroxyanisole, butylated hydroxytoluene, ascorbic acid, dimethylfumarate, and n-acetylcysteine. Once induced to differentiate into neuronal cells, the cells can be used for cell therapy, gene therapy, or both, for treatment of diseases, disorders, or conditions of the central nervous system.

  • Patent number: 7056738
    Abstract: Marrow stromal cells (MSCS) are adult stem cells from bone marrow that can differentiate into multiple non-hematopoietic cell lineages. Colonies of human MSCs were shown to contain both small, rapidly self-renewing stem cells (RS cells) and large, more mature cells (mMSCs). Samples enriched for RS cells had a greater potential for multipotential differentiation than samples enriched for mMSCs. Also, RS cells have a series of surface epitopes and expressed proteins that can be used to differentiate RS cells from mMSCs. The results suggest that it will be important to distinguish the two major sub-populations of MSCs in defining their biology and their potentials for cell and gene therapy.
