Systems, methods, and apparatuses are presented that involve forming patterns on neo-epithelium that allow increased functionality and may more nearly resemble the original epithelium. In one instance, a patterned neo-epithelium dressing for treating a tissue site having granulation tissue includes an interface member for placing proximate the granulation tissue and a plurality of three-dimensional features formed on a second, patient-facing side of the interface member. Other systems, methods, and apparatuses are disclosed.

1. A patterned neo-epithelium dressing for treating a skin tissue site having granulation tissue, the patterned neo-epithelium dressing comprising: an interface member having a first side; anda second, patient-facing side configured to be placed proximate to the granulation tissue,the second, patient-facing side of the interface member having a surface topography defined by a plurality of ridges and grooves formed in a pattern to mimic intact human skin. 2. The patterned neo-epithelium dressing of claim 1, wherein the interface member is formed with a fluid passageway that fluidly couples the first side and the second, patient-facing side. 3. The patterned neo-epithelium dressing of claim 1, wherein the interface member has a plurality of pores having an average pore size greater than 5 μm and smaller than 1000 μm. 4. The patterned neo-epithelium dressing of claim 1, wherein the pattern is configured to mimic an intact analogous human skin pattern based on the patient's skin near the wound or a duplicate body part. 5. The patterned neo-epithelium dressing of claim 1, wherein the pattern is configured to mimic a location-specific human skin pattern based on the general features of a specific area of a generic body. 6. The patterned neo-epithelium dressing of claim 1, wherein the interface member comprises a thin member bonded to a foam. 7. The patterned neo-epithelium dressing of claim 1, wherein the interface member comprises: a thin member having a first side and a second, patient-facing side;a hydrophilic material having a first side and a second, patient-facing side; andwherein the second, patient-facing side of the hydrophilic material is coupled to the first side of the thin member. 8. The patterned neo-epithelium dressing of claim 1, further comprising a protein coated on the plurality of ridges and grooves. 9. A method of treating a wound at a tissue site of a patient, the method comprising: locating granulation tissue at the tissue site;deploying a patterned neo-epithelium dressing on the granulation tissue, the dressing comprising: an interface member having (i) a first side, (ii) a second, patient-facing side, and (iii) the second patient-facing side having a surface topography defined by a plurality of ridges and grooves formed in a pattern configured to mimic intact human skin, and wherein the second, patient-facing side is deployed proximate the granulation tissue; andapplying a contact pressure on the patterned neo-epithelium dressing. 10. The method of claim 9, wherein the locating comprises promoting the formation of granulation tissue using reduced pressure at the tissue site. 11. The method of claim 10, wherein the step of promoting the formation of granulation tissue comprises applying a reduced-pressure manifold proximate to the tissue site, covering the reduced-pressure manifold with a sealing member, and providing reduced pressure to the reduced-pressure manifold. 12. The method of claim 9, wherein applying the contact pressure comprises: deploying a sealing member over the patterned neo-epithelium dressing and a portion of the patient's skin, the sealing member having a first side and a second, patient-facing side; andproviding reduced pressure to the second, patient-facing side of the sealing member. 13. The method of claim 9, wherein applying the contact pressure comprises deploying a pressure wrap over the first side of the patterned neo-epithelium dressing. 14. The method of claim 9, wherein the interface member has a plurality of pores having an average pore size greater than 5 μm and smaller than 1000 μm. 15. A system for treating a skin tissue site having granulation tissue on a patient, the system comprising: a patterned neo-epithelium dressing configured to be disposed proximate to granulation tissue on the skin tissue site, wherein the patterned neo-epithelium dressing comprises: an interface member having (i) a first side, (ii) a second, patient-facing side configured to be placed proximate the granulation tissue, the second, patient-facing side having a surface topography defined by a plurality of ridges and grooves formed in a pattern configured to mimic intact human skin, and (ii) one or more fluid passageways that fluidly couple the first side and the second, patient-facing side;a sealing member for placing over the patterned neo-epithelium dressing and the patient's epidermis;a reduced-pressure interface fluidly coupled to the sealing member; anda reduced-pressure source fluidly coupled to the reduced-pressure interface. 16. The system of claim 15, the interface member has a plurality of pores having an average pore size larger than 5 μm and smaller than 1000 μm. 17. The system of claim 15, wherein the pattern is configured to mimic intact analogous human skin pattern based on the patient's skin near the wound or a duplicate body part. 18. The system of claim 15, wherein the pattern is configured to mimic a location-specific human skin pattern based on a specific area of a generic human body. 19. The system of claim 15, wherein the interface member comprises a polyurethane film bonded to a foam.
