一项早些年的研究表明血细胞值仅为正常一半的垂危儿童接受输血后并未比未接受者有所好转。
And a study carried out earlier this year found that critically ill children whose red blood-cell counts had dropped by half fared no better after a transfusion than those who did not receive one.
当研究团队用中性抗体阻止癌细胞释放这种化学信号时，造血细胞就可以正常工作。
When the team blocked the release of this chemical signal with neutralizing antibodies, the blood-making cells went about their normal business.
这幅图片显示了两种红血细胞：正常红血细胞(红色背景)和患有镰形细胞贫血症的红血细胞(前景)。
This image shows two red blood cells: a normal red blood cell (colored red in the background) and a red blood cell affected by sickle-cell anemia (in the foreground).
