TREATMENT OF INTERVERTEBRAL DISC DEGENERATION USING HUMAN UMBILICAL CORD TISSUE-DERIVED CELLS
Methods for treating a patient having a disease or condition related to IVD degeneration are provided. The methods comprise administering cells obtained from human umbilical cord tissue, or administering pharmaceutical compositions comprising such cells or prepared from such cells and optionally a hydrogel. In some embodiments, administering the cells promotes repair and regeneration of degenerated IVD tissue in the patient. Pharmaceutical compositions for use in the inventive methods, as well as kits for practicing the methods are also provided.
1 . A method treating disc degeneration in a subject comprising administering a pharmaceutical composition comprising a mixture of a hydrogel and an isolated homogenous population of cells obtained from human umbilical cord tissue into an intervertebral disc,
wherein the umbilical cord tissue is substantially free of blood,
wherein the hydrogel comprises fibrinogen and thrombin, and
wherein the isolated homogenous population of cells is capable of self-renewal and expansion in culture, has the potential to differentiate and has the following characteristics:
does not express CD31, CD34, CD117, telomerase and HLA-DR;
expresses chemokine receptor ligand 3, and/or granulocyte chemotactic protein;
expresses CD10, CD13, CD44, CD73, PDGFr-alpha and CD90; and
expresses, relative to a human fibroblast, mesenchymal stem cell, or iliac crest bone marrow cell, increased levels of interleukin 8 and reticulon 1.
2 . The method of claim 1 , wherein the pharmaceutical composition is administered by injection.
3 . The method of claim 1 , wherein the pharmaceutical composition further comprises at least one other cell type and/or at least one agent.
4 . The method of claim 3 , wherein the at least one agent is a trophic factor.
5 . The method of claim 4 , wherein the trophic factor is selected from the group consisting of TGF-beta, GDF-5, PDGF-BB and TIMP1.
6 . The method of claim 1 , wherein the pharmaceutical composition is administered into a degenerated intervertebral disc.
7 . The method of claim 6 , wherein the pharmaceutical composition is administered into the nucleus pulposus or into the annulus fibrosus of the intervertebral disc.
8 . The method of claim 1 , wherein the cells are undifferentiated.
9 . A method of treating intervertebral disc degeneration in a subject comprising administering a mixture of a hydrogel and an isolated homogenous population of cells obtained from human umbilical cord tissue into an intervertebral disc,
wherein the umbilical cord tissue is substantially free of blood,
wherein the hydrogel comprises fibrinogen and thrombin, and
wherein the isolated homogenous population of cells is capable of self-renewal and expansion in culture, has potential to differentiate and has the following characteristics:
does not express CD31, CD34, CD117, telomerase and HLA-DR;
expresses chemokine receptor ligand 3, and/or granulocyte chemotactic protein;
expresses CD10, CD13, CD44, CD73, PDGFr-alpha and CD90; and
expresses, relative to a human fibroblast, mesenchymal stem cell, or iliac crest bone marrow cell, increased levels of interleukin 8 and reticulon 1.
10 . The method of claim 9 , wherein the isolated homogenous population of cells and the hydrogel are administered by injection.
11 . The method of claim 9 , further comprising administration of at least one other cell type simultaneously with, or before, or after, the isolated homogenous population of cells obtained from human umbilical cord tissue.
12 . The method of claim 9 further comprising administration of least one agent.
13 . The method of claim 9 , wherein the at least one agent is a trophic factor.
14 . The method of claim 13 , wherein the trophic factor is selected from the group consisting of TGF-beta, GDF-5, PDGF-BB and TIMP1.
15 . The method of claim 14 , wherein the trophic factor exerts a trophic effect on the isolated homogenous cell population obtained from human umbilical cord tissue.
16 . The method of claim 9 , wherein the isolated homogenous cell population and hydrogel are administered into a degenerated intervertebral disc.
17 . The method of claim 16 , wherein the isolated homogenous cell population and hydrogel are administered into the nucleus pulposus of the intervertebral disc.
18 . The method of claim 16 , wherein the isolated homogenous cell population and hydrogel are administered into the annulus fibrosus of the intervertebral disc.
19 . The method of claim 9 , wherein the cells are undifferentiated.
