1. The red marrow has hemopoiesis function.

2. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes.

3. It produces red blood cells in the inner red marrow and stores fat in the yellow marrow.

4. Objective To observe the therapeutic effects of autologous red marrow combined with bone morphogenetic protein (BMP) on the delayed union of tibial fracture.

5. All other blood-cell formation occurs in red marrow, which also takes part in destruction of old erythrocytes (red blood cells).

6. To compare with autologous bone graft, deproteined bovine cancellous bone and an autogenous red marrow had an identical effect for repairing bony cavity defect.

7. Results:The metaphysis and the periphery of the secondary center of ossification were red marrow. They showed marked enhancement on T 1WI. Enhancement ratio declined in both regions with age.

8. Bony spicules are seen throughout the centers of ossification(), making areas of spongy bone with red marrow between the spicules.

9. Bone marrow that actively produces blood cells is called red marrow, and bone marrow that no longer produces blood cells is called yellow marrow.

10. Objective To investigate the efficacy of the repair with decalcified bone matrix(DBM)and bone cement(BC)combined with autologous red marrow(RM) for canine femoral defect.

11. Results of animal experiments and clinical experiences indicated that bone grafts impregnated with autologous red marrow could promote osteogenesis.
