All cases were positive. The result was coincided with human tumor transplants in athymic nude mouse by Bauer. It is shown that Ewing' s sarcoma can express BMP. So we support the hypothesis that Ewing' s sarcoma originates from primitive multipotential cells and can pluripotentially differentiate.展开更多
