An apparatus for developing peri-operatively to a patient a cell suspension from a skin tissue sample, and for immediately applying the cell suspension to a graft site of the patient, comprising a first member, a second member, a set of tools required for cell harvesting and a spray nozzle for applying the cell suspension to the graft site, wherein: (i) the first member includes: (a) a heating means suitable for heating an enzyme solution to a required temperature and which is capable of maintaining that solution at the desired temperature for a suitable amount of time, wherein the pre-warmed enzyme solution is used to incubate a skin tissue sample and contains an amount of enzyme sufficient to dissociate cellular stratum in the skin tissue sample; (b) a filter recess comprising a filter means of a filter size between 50 μm and 200 μm, for removing cellular congregates from cells harvested from the skin tissue sample, to form the cell suspension that is suitable for immediate dispersion to the graft site; (c) at least a fluid containment well for storage of a nutrient solution suitable for direct application to the graft site, wherein the nutrient solution is used to suspend the cells following release of the cells from the skin tissue sample; and (d) a storage compartment for storing the set of tools required for cell harvesting; and (ii) the second member forms a reservoir for withholding the skin tissue sample and the nutrient solution in fluid containment, wherein the reservoir is of sufficient size to permit manipulation of the skin tissue sample, permitting separation of the cellular stratum and harvesting of the cells from the stratum suitable for grafting; wherein the first member provides a seat upon which the second member may be placed during manipulation of the skin tissue sample. (i) the first member includes: (a) a heating means suitable for heating an enzyme solution to a required temperature and which is capable of maintaining that solution at the desired temperature for a suitable amount of time, wherein the pre-warmed enzyme solution is used to incubate a skin tissue sample and contains an amount of enzyme sufficient to dissociate cellular stratum in the skin tissue sample; (b) a filter recess comprising a filter means of a filter size between 50 μm and 200 μm, for removing cellular congregates from cells harvested from the skin tissue sample, to form the cell suspension that is suitable for immediate dispersion to the graft site; (c) at least a fluid containment well for storage of a nutrient solution suitable for direct application to the graft site, wherein the nutrient solution is used to suspend the cells following release of the cells from the skin tissue sample; and (d) a storage compartment for storing the set of tools required for cell harvesting; and (a) a heating means suitable for heating an enzyme solution to a required temperature and which is capable of maintaining that solution at the desired temperature for a suitable amount of time, wherein the pre-warmed enzyme solution is used to incubate a skin tissue sample and contains an amount of enzyme sufficient to dissociate cellular stratum in the skin tissue sample; (b) a filter recess comprising a filter means of a filter size between 50 μm and 200 μm, for removing cellular congregates from cells harvested from the skin tissue sample, to form the cell suspension that is suitable for immediate dispersion to the graft site; (c) at least a fluid containment well for storage of a nutrient solution suitable for direct application to the graft site, wherein the nutrient solution is used to suspend the cells following release of the cells from the skin tissue sample; and (d) a storage compartment for storing the set of tools required for cell harvesting; and (ii) the second member forms a reservoir for withholding the skin tissue sample and the nutrient solution in fluid containment, wherein the reservoir is of sufficient size to permit manipulation of the skin tissue sample, permitting separation of the cellular stratum and harvesting of the cells from the stratum suitable for grafting;
