    摘要: Implantable therapy systems are disclosed for the local and controlled delivery of a biologically active factor to the brain, spinal cord and other target regions of a subject suffering from a debilitating condition. The method of the invention involves surgically exposing an insertion site, generally located above a predetermined treatment site (12), in a patient. A cannula (20), having an obturator (30) or dilator (104) positioned therein, is inserted at the insertion site, defining a pathway to the treatment site. In some instances, the cannula can be inserted along the path of a guidewire (102) previously positioned at the treatment site. The cannula (20) is preferably a low friction polymeric material such as polytetrafluoroethylene. The cannula (20) generally has an open proximal end for receiving the obturator (30) or dilator (104), and an open distal end, preferably a tapered end, for delivery of neurologically active factors to the treatment site (12). The obturator (30) is then removed from the cannula (20), and a biocompatible tethered vehicle (40) containing a biologically active material is inserted into the cannula along the passageway. A pusher can be inserted within the cannula, behind the vehicle (40), to position the proximal end of the vehicle at the distal end of the cannula (20b). Once the vehicle (40) is positioned near the distal end of the cannula (20), the cannula is removed from the passageway, followed by the pusher, leaving the vehicle (40) positioned at the treatment site (12).

    摘要: Implantable therapy systems are disclosed for the local and controlled delivery of a biologically active factor to the brain, spinal cord and other target regions of a subject suffering from a dibilatating condition. The method of the invention involves surgically exposing an insertion site, generally located above a predetermined treatment site (12), in a patient. A cannula (20), having an obturator (30) or dilator (104) positioned therein, is inserted at the insertion site, defining a pathway to the treatment site. In some instances, the cannula can be inserted along the path of a guidewire (102) previously positioned at the treatment site. The cannula (20) is preferably a low friction polymeric material such as polytetrafluoroethylene.

A pusher can be inserted within the cannula, behind the vehicle (40), to position the proximal end of the vehicle at the proximal tip of the cannula (20b). Once the vehicle (40) is positioned near the proximal end of the cannula (20), the cannula is removed from the passageway, followed by the pusher, leaving the vehicle (40) positioned at the treatment site (12).

    摘要: A combined therapy of human umbilical cord blood cells (hUCB) and G-CSF at the acute stage of TBI was tested as a therapeutic for progressive secondary effects of chronic TBI. Rats were treated with saline carrier, or therapeutic in carrier as follows; G-CSF, hUCB, or hUCB and G-CSF, 7-days after TBI. Eight weeks later, behavioral testing was performed and brains harvested to analyze hippocampal cell loss, neuroinflammatory response, and neurogenesis. Results revealed that the monotherapies partially suppressed neuroinflammation and reduced hippocampal cell loss. However, combined therapy of hUCB and G-CSF robustly dampened neuroinflammation, while enhancing endogenous neurogenesis and reducing hippocampal cell loss. Vigorous and long-lasting recovery of motor function accompanied the combined therapy, which was either moderately or short-lived in the monotherapy conditions. These results suggest that combined treatment rather than monotherapy appears optimal for abrogating histophalogical and motor impairments in chronic TBI.

    摘要: A cell type that is a complete match of the transplant recipient appears as an optimal scenario to open treatment options to a large patient population with minimal complications. The use of autologous bone marrow or umbilical cord blood has been proposed as a good source of stem cells for cell therapy. Menstrual blood is found to be another important source of stem cells. Assays of cultured menstrual blood reveal that they express embryonic like-stem cell phenotypic markers and neuronal phenotypic markers under appropriate conditioned media. Oxygen glucose deprivation stroke models show that OGD-exposed primary rat neurons, co-cultured with menstrual blood-derived stem cells or exposed to the media from cultured menstrual blood, exhibited significantly reduced cell death. Transplantation of menstrual blood-derived stem cells, either intracerebrally or intravenously, after experimentally induced ischemic stroke in adult rats also significantly reduced behavioral and histological impairments compared to vehicle-infused rats.

    摘要: A composition of an immunosuppressant protein (HISP) which is achieved by the steps of obtaining supernatant from hNT neuronal cells; exposing the supernatant to preparative polyacrylamide gel; placing the active isoelectric fraction on a Blue Sepharose column to bind albumin; and collecting the free fraction containing the concentrated, isolated HISP. The HISP is anionic, has a molecular weight of 40-100 kDa, an isoelectric point of about 4.8 and is obtained from the supernatant of hNT cells. HISP can suppress proliferation of responder peripheral blood mononuclear cells in allogeneic mixed lymphocyte cultures; HISP can suppress T-cell proliferation and IL-2 production in response to phorbol 12-myristate 13-acetate (PMA), ionomycin and concanavalin-A. HISP does not act through the T-cell receptor-CD3 complex or via altered accessory signal cells.

    摘要: The subject invention pertains to tumor cell lines useful for increasing the proliferation potential of any human or animal cell in culture, thereby providing immortalized or continuous cell lines and cultures. The invention also concerns proliferation factors, and compositions containing the factors, which are capable of increasing the proliferation potential of any human or other animal cell in culture. The subject invention further pertains to a method for proliferating cells in culture by contacting cells with the proliferation factors. The proliferated cells can range in plasticity and can include, for example, blast cells, fertilized ova, non-fertilized gametes, embryonic stem cells, adult stem cells, precursor or progenitor cells, and highly specialized cells. Optionally, the cells can be induced to cease proliferation. The proliferated cells of the subject invention are useful for cell therapy, cell/gene therapy, biological production of molecules, and as in vitro models for research, toxicity testing, and drug development.

    摘要: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease characterized by degeneration of motor neurons in the spinal cord and brain. Increasing evidence shows autoimmune mechanisms likely promote disease progression. Human umbilical cord blood (hUCB) derived plasma is rich in cytokines and growth factors that are required for growth and survival of cells during hematopoiesis. hUCB plasma attenuated the hyperactive response (Group III) and potentiated the normal response in Group I ALS patients, but did not alter that of the non-responders to PHA (Group II). The elevated activity of caspase 3/7 observed in the MNCs from ALS patients was significantly reduced by hUCB plasma treatment. The ability of hUCB plasma to modulate the mitogen cell response and reduce caspase activity suggest that the use of hUCB plasma alone, or with stem cells, may prove useful as a therapeutic in ALS patients.
