A system in accordance with embodiments of the present invention includes a cannula interconnected to a washing reservoir by a flexible conduit. The washing reservoir has an outlet that is connected to the inlet of a tissue collection reservoir. Washed tissue can be removed from the washing reservoir by tipping or otherwise causing the outlet of the washing reservoir to be covered by washed tissue. Tissue collected in the tissue collection reservoir can be readied for injection into a body by removing an inner or filter chamber from an outer chamber and blocking holes in the body of the inner chamber to use the inner chamber as part of a syringe.
