    [0002] The method of claim 1, wherein said ECM comprises flowable ECM.
    [0003] The method of claim 1 or 2, wherein said cellular composition and said ECM are printed onto said surface, preferably wherein said depositing is accomplished by inkjet printing.
    [0004] The method of any of claims 1-3, wherein (i) said surface is an artificial surface; or (ii) said surface is decellularized tissue or a decellularized organ.
    [0005] The method of any of claims 1-4, wherein said ECM is placental ECM.
    [0006] The method of any of claims 1-5, further comprising deposition of a cell attachment peptide, a cell attachment protein, a cytokine, a glycosaminoglycan, a synthetic polymer, tenascin C or a fragment thereof, and/or a titanium-aluminum-vanadium (Ti6Al4V) composition.
