家园 那个人造血有副作用

我在电视上也曾经看到过介绍人造血的电视科教片。

维基百科上有一点内容(链接),这个做过临床实验,有一定的副作用,恐怕要再多加研究之后才能达到实际应用。

The products yielded a 30% increase in the risk of death and about a threefold chance of having a heart attack of for the recipients. More than 3,711 patients were tested in sixteen studies using five types of artificial blood.[7]

五角大楼在搞一个利用造血干细胞来造血的机器。据说是血型通用现造现用。这个估计成本比较高,可行性不知道具体怎么样。即使成功,军事上先用,成本如果能够降低的话,民用也许也是可以的。

Scientists from the experimental arm of the Pentagon of United States began creating artificial blood to transport blood to remote areas and transfuse blood to wounded soldiers more quickly in 2010.[10] The blood is made from the hematopoietic stem cells removed from umbilical cord between the mother and fetus of humans after birth using a method called blood pharming. Pharming has been used in the past on animals and plants to create medical substances in large quantities. Each cord can produce approximately 20 units of blood or three blood transfusions. The blood is being produced for the Defense Advanced Research Projects Agency by Arteriocyte. The Food and Drug Administration has examined and approved the safety of this blood from previously submitted O-negative blood. Using this particular artificial blood will reduce the costs per unit of blood from $5,000 to equal or less than $1,000.[10] This blood will also serve as a blood donor to all blood types. Pharmed blood may be used in human trials in 2013.

河里面的游识猷在科学松鼠会那边写过一篇《缺啥别缺血》,这个可以看一下。
