  • Publication number: 20250019656
    Abstract: The present disclosure provides distinct therapeutic populations of cells that form a pharmaceutical composition useful in hematopoietic stem/progenitor cell transplant. For example, the present disclosure provides a therapeutic population of cells, comprising an enriched population of hematopoietic stem/progenitor cells, memory T cells, regulatory T cells, and wherein the population of cells is depleted of naïve conventional ??-T cells. The present disclosure further provides methods of treatment using the therapeutic population of cells. In other embodiments, the present disclosure provides methods of producing a therapeutic population of cells.

  • Publication number: 20240408198
    Abstract: Embodiments of the disclosure provide compositions, kits, and methods for allogeneic hematopoietic cell transplantation (alloHCT) to patients. In an embodiment, a therapeutic composition for alloHCT includes at least first and second populations of isolated CD45+ cells (ICC). At least a portion of the CD45+ cells in the first population may have an antibody bound to a marker on the cell surface which is used to separate CD34+ cells from a mixture of nucleated cells (MNC) from donor or invitro produced blood. The MNC may comprise various cell types in various amounts, for example, about 70% CD34+ cells, less than about 5% CD3+ cells and less about 20% granulocytes. The ICC's in the second population include regulatory T cells which are typically at least about 50% of the population. Embodiments of the disclosure are particularly useful for treatment of hematologic cancers (e.g., leukemia, lymphoma), sickle cell anemia, GVHD, autoimmune and other diseases.

  • Patent number: 9903854
    Abstract: A point-of-test diagnostic chip that is capable of simultaneous evaluation of blood coagulation time (INR Value) and hematocrit level. A finger prick volume of blood is placed at the inlet of the device, and the residual vacuum contained within the device provides a pressure gradient to drive the flow of whole blood. The INR value is determined by the distance the blood traverses down the channel before it coagulates. The channel is primed with tissue factor and phospholipids to induce coagulation. A control channel is primed with anticoagulants for use as a way to normalize initial loading times. The hematocrit level is determined by sedimentation of blood cells into a trench and the interface between blood cells that have overfilled the trench and plasma provide a visual readout.

  • Publication number: 20160305936
    Abstract: The present invention describes a spatial addressing technique that uses a very high-density micro-pore array for high-throughput screening of biological interactions. The therapeutic, diagnostic, and drug-discovery implications of being able to identify, select and characterize specific protein-protein, protein-DNA and/or protein-carbohydrate interactions from heterogeneous populations of millions (to billions) of cells is discussed. Importantly, this technique possesses the screening and selection capacity of current display-based screening systems (i.e. millions-billions) but with greater efficiency and shorter time.

  • Patent number: 8906669
    Abstract: A sequential flow analysis tool comprising a microfluidic device having a fluid path defined within a substrate between an input and an output is described. The device includes a capture chamber provided within but offset from the fluid path, the capture chamber extending into the substrate in a direction substantially perpendicular to the fluid path such that operably particles provided within a fluid flowing within the fluid path will preferentially collect within the capture chamber.

  • Publication number: 20120276641
    Abstract: A device for blood-plasma separation and plasma-based blood analysis is described. The device uses blood samples smaller than 5 ?L, (directly from the finger) and flow is achieved with a degassing-driven flow technique that causes blood to flow spontaneously into air-filled dead-end channels without external pumping mechanisms.

  • Publication number: 20120219727
    Abstract: The formation of a barrier layer within individual channels or cavities of a microfluidic device is described. The barrier layer is effected through a gas phase deposition process, desirably implemented in a plasma environment using a gas plasma reactor. Judicious selection of a precursor compound used within the gas plasma reactor can provide for generation of a layer on the individual surfaces. Desirably the surface or barrier layer is generated through the chemical adsorption of a metalloid oxide such as a silicon oxide layer on the surface of the individual channels or cavities.

  • Publication number: 20050105265
    Abstract: A docking module for conventional small form factor disk drives provides, in one embodiment, space for two such disk drives embedded in tray loaders, within a standard 3.5 inches halve height floppy bay. The docking module provides hot swappable insertion and removal of tray loaders together with disk drives. The bay is provided within a housing member. A button attached to a lever mechanism disconnects the docking module connector from the tray loader connector and partially pull out the loader when the button is pushed; An EMI shield fixedly coupled to the tray loaders each provide a barrier to electromagnetic interference.
