    • Cells are generated from skin biopsies for use in cell implantation by identifying a source of skin cells that have a surface concentration of at least one cell selected from the group consisting of keritinocytes and/or melanocytes; taking a sample of tissue from the surface area; mechanically disaggregating the tissue samples; collecting the disaggregated cells; washing the disaggregated cells; filtering the washed disaggregated cells; providing a cell suspension with filtered and washed keritinocytes and/or melanocytes; and suspending the cell suspension in a medium. In greater particularity, the method may comprise a) identifying a source of skin cells that have a surface concentration of at least 400 cells per square millimeter of surface area of at least one cell selected from the group consisting of keritinocytes and/or melanocytes; b) taking a sample of those skin cells and culturing them to enrich for cells selected from the group consisting of keritinocytes and melanocytes to form cultured cells for transplantation purposes c) concentrating the cells selected from the group consisting of keritinocytes and/or melanocytes from the cultured mass of cells; and d) differentiating the concentrated cells selected from the group consisting of keritinocytes an/or melanocytes.

    • A functionalized tip is incorporated into catheters for the cytometric delivery of cells into the brain and other body parts. For use in the brain, the tip forms part of a neurosurgical probe having a proximal end and a distal end. In addition to the functionalized tip, the probe has at least one cell slurry delivery lumen and a plurality of optical fibers configured along the probe, terminating in the tip to provide the photo-optical capability needed to monitor the viability and physiological behavior of the grafted cells as well as certain characteristics of the cellular environment. Details are also presented of the use of a neurocatheter having a cytometric tip of the type disclosed in the invention, as employed within the context of a feedback and control system for regulating the number of cells delivered to the brain of a patient.
