Bone marrow cells as a source of neurons for brain and spinal cord repair

Bone marrow cells as a source of neurons for brain and spinal cord repair
Bone marrow stromal cells (BMSC) differentiate into neuron-like phenotypes in vitro and in vivo, engrafted into normal or denervated rat striatum. The BMSC did not remain localized to the site of the graft, but migrated throughout the brain and integrated into specific brain regions in various architectonic patterns. The most orderly integration of BMSC was in the laminar distribution of cerebellar Purkinje cells, where the BMSC-derived cells took on the Purkinje phenotype. The BMSC exhibited site-dependent differentiation and expressed several neuronal markers including neuron-specific nuclear protein, tyrosine hydroxylase and calbindin. BMSC can be used to target specific brain nuclei in strategies of neural repair and gene therapy.

Antigen specific T cell therapy
Provided are methods for generating immune cells of the desired type and specificity in a host. The methods may be used to treat a disease or disorder, such as a tumor in a patient. Target cells, preferably hematopoietic stem cells such as primary bone marrow cells are transfected with a polynucleotide encoding a T cell receptor with the desired specificity. The transfected cells are then transferred to the host where they develop into mature, functional immune cells. The source of the T cell receptor can determine the stem cell's fate. Thus transfecting stem cells with TCRs from cytotoxic cells will lead to the generation of cytotoxic T cells in the host, while TCRs from helper cells will produce helper cells. Both arms of T cell immunity can be generated simultaneously in a host. Additionally, the immune response to the desired antigen can be further stimulated by immunizing the host with the antigen.

Isolation of human umbilical cord blood-derived mesenchymal stem cells
InactiveUS20120142102A1Symptoms improvedMicrobiological testing/measurementCell culture supports/coatingCell-Extracellular MatrixECM Protein
Human umbilical cord blood (UCB) contains mesenchymal stem cells (MSCs) that have higher multipotentiality than adult marrow-derived MSCs. However, it has been difficult to obtain these cells because the frequency of MSCs in UCB is extremely rare (0.4-30 out of 1×108 mononuclear cells). To date, the isolation of MSCs has depended upon their plastic-adhesion capacity. Some “true” MSCs could be missed because their ability to adhere to plastic may be poor. Previous studies demonstrated extracellular matrix (ECM) made by bone marrow cells enhanced MSC attachment and proliferation, and retained their stem cell properties. The present invention provides methods for isolating MSCs from umbilical cord blood by adherence to an ECM and uses for the isolated stem cells.
