Human Tissue Repository for Wound Care

The study design is a multicenter study involving the collection of human biological specimens in Subjects with various wound classifications and types for the purpose of a Human Tissue Repository to be used as a resource for future tissue repair research at KCI USA, Inc. Subjects participating in this study will have a 6mm tissue punch biopsy or equivalent tissue specimen harvested from the healthiest margin of the wound. Tissue collection may occur at Visits 2, 3, 4 and 5. Visit 2 may be combined with Screening, Visit 1. Subjects will have a minimum of one (1) and a maximum of four (4) specimen collection visits. Specimens may be collected from one or multiple different tissues (connective tissue, muscle, bone, and dermis) at any or all visits. Each specimen will be placed in a separate appropriate vial. Necrotic tissue with eschar and bodily fluids such as blood, wound fluid or sputum will not be collected. Tissue from healthy, healing wounds will also be accepted. Tissue collection visits shall occur at least twenty-four (24) hours apart. Ten (10) to twenty-five (25) percent of the sites will be selected to collect all the specimens in cryovials containing a pre-aliquoted amount (1.5mL) of RNAlater. Ten (10) to twenty-five (25) percent of the sites will be selected to collect all the specimens in cryovials containing a pre-aliquoted amount of HypoThermosol. The remaining sites will collect all the specimens in a vial containing no diluents. All samples will be coded by the collection site prior to shipment to KCI.
