Abstract

The present invention provides compositions comprising human placental telopeptide collagen, methods of preparing the compositions, methods of their use and kits comprising the compositions. The compositions, kits and methods are useful, for example, for augmenting or replacing tissue of a mammal.

Claims

1-48. -48. (canceled)

49. A method of treating a wound comprising contacting the wound with a composition comprising placental extracellular matrix, wherein said composition comprises at least 80% collagen by dry weight and wherein said composition comprises at least 10% elastin by dry weight.

50. The method of claim 49, wherein said composition is used as a wound filler.

51. The method of claim 49, wherein said composition is applied directly to the site of the wound.

52. The method of claim 49, wherein said composition is shaped to fit the site of the wound.

53. The method of claim 49, wherein said wound is a pressure ulcer, venous ulcer, diabetic ulcer, chronic vascular ulcer, tunneled/undermined wound, surgical wound, trauma wound, or draining wound.

54. A method of augmenting tissue repair in a subject comprising contacting said tissue with a composition comprising placental extracellular matrix, wherein said composition comprises at least 80% collagen by dry weight and wherein said composition comprises at least 10% elastin by dry weight.

55. The method of claim 54, wherein said tissue is internal to the subject.
