Abstract

Provided herein are methods of producing trabecular bone material, such as trabecular bone or trabecular bone matrix and cells useful in preparing the trabecular bone material.

Claims (10)

1. A method of producing trabecular bone material, comprising: culturing CLC3 knockout osteoblasts ex vivo in culture medium for a length of time such that trabecular bone material is produced.

2. The method of claim 1 , wherein the CLC3 knockout osteoblasts are obtained by culturing CLC3 knockout mesenchymal stem cells or osteoblast precursor cells in osteoblast differentiation medium.

3. The method of claim 2 , wherein the mesenchymal stem cells or osteoblast precursor cells are human or murine.

4. The method of claim 2 , wherein the osteoblast differentiation medium comprises ascorbic acid and a phosphate source.

5. The method of claim 4 , wherein the osteoblast differentiation medium does not contain a glucocorticoid.

6. The method of claim 4 , wherein the phosphate source is glycerol-2-phosphate.

7. The method of claim 1 , wherein the osteoblasts are human or murine.

8. The method of claim 1 , wherein the CLC3 knockout knockdown osteoblasts are prepared by:

a. isolating CLC3 knockout mesenchymal stem cells or osteoblast precursor cells from a CLC 3 knockout transgenic animal; and

b. differentiating the CLC3 knockout mesenchymal stem cells or osteoblast precursor cells to an osteoblast phenotype, thereby producing a CLC3 knockout osteoblast capable of producing trabecular bone material.
