摘要:
An in vivo model for human bone metabolism. Human marrow stromal fibroblasts are isolated, expanded in culture, combined with ceramic powder (hydroxyapatite) delivery vehicles with or without fibrin glue and implanted into a mammal. This protocol results in the formation of self-maintained human bone which supports hematopoiesis. This model system can be used to screen compounds which inhibit or stimulate bone formation. The marrow stromal fibroblast delivery vehicles can be implanted into humans to augment bone implants or to repair bone defects.
