Abstract

Provided herein are methods of using adherent placental stem cells and placental stem cell populations, and methods of culturing, proliferating and expanding the same. Also provided herein are methods of differentiating the placental stem cells. Further provided herein are methods of using the placental stem cells to formulate implantable or injectable compositions suitable for administration to a subject. Still further provided herein are provides methods for treating bone defects with stem cells and compositions comprising stem cells.

Claims

1. A method for treating a bone defect in a subject, wherein said bone defect is an osteolytic lesion associated with multiple myeloma, bone cancer, or metastatic cancer characterized by bone metastases, comprising administering to a subject in need thereof an implantable or injectable composition comprising a population of placental stem cells, wherein said population is predominantly CD34⁻

, CD10⁺, CD105⁺, and CD200⁺, and wherein said stem cells express HLA-G, thereby treating the bone defect in the subject.

2. The method of claim 1, wherein said placental stem cells have been passaged at least five times.

3. The method of claim 1, wherein said population is predominantly CD34⁻

, CD45⁻

, CD10⁺, CD90⁺, CD105⁺, and CD200⁺.

4. The method of claim 1, wherein said placental stem cells comprise at least 70% of cells in said composition.

5. The method of claim 1, wherein said placental stem cells comprise at least 90% of cells in said composition.

6. The method of claim 1, wherein said osteolytic lesion is an osteolytic lesion associated with multiple myeloma.

7. The method of claim 1, wherein said osteolytic lesion is an osteolytic lesion associated with bone cancer.

8. The method of claim 1, wherein said osteolytic lesion is an osteolytic lesion associated with metastatic cancer.

9. The method of claim 1, wherein said placental stem cells are cells from a placental stem cell bank.

10. The method of claim 1, wherein said composition is formulated as a suspension or liquid that can be administered intravenously.

11. The method of claim 1, wherein said composition comprises 5×

10⁶ said placental stem cells per milliliter.

12. The method of claim 1, wherein said composition comprises an implantable substrate or matrix.

13. The method of claim 1, wherein said composition comprises human serum albumin (HSA) and dextran-40.

14. The method of claim 1, wherein said placental stem cells are autologous to said subject.

15. The method of claim 1, wherein said placental stem cells have been cryopreserved.

16. The method of claim 1, wherein said population is predominantly CD73⁺.

17. The method of claim 16, wherein at least 80% of the placental stem cells in said population are CD73⁺, CD105⁺, and CD200⁺.

18. The method of claim 16, wherein at least 90% of the placental stem cells in said population are CD73⁺, CD105⁺, and CD200⁺.

19. The method of claim 1, wherein said population has been passaged at least three times.

20. The method of claim 19, wherein said population has been passaged no more than ten times.
