当今有不少机构在开展干细胞治疗，干细胞治疗真的有效吗？干细胞治疗安全吗？事实上许多问题悬而未决，老狼现将干细胞“神奇疗法”容易给公众造成的“十大误区”分享在此：

Top Ten Things to Know About Stem Cell Treatments" I1 E% J- t, Q2 N
  s  o  F" T1 E* z, s  o1 o: N
Many clinics that are offering stem cell treatments make claims about what stem cells can and cannot do that are not supported by our understanding of science. The information on this page corrects some of the misinformation that is being widely circulated.

1.  There are different types of stem cells—each with their own purpose.( p0 u7 [% D& k# t0 W; o+ y8 \$ Y
根本不存在“包治百病”的干细胞
There are many different types of stem cells that come from different places in the body or are formed at different times in our lives. These include embryonic stem cells that exist only at the earliest stages of development and various types of ‘tissue-specific’ or ‘adult’ stem cells that appear during fetal development and remain in our bodies throughout life.3 \# ^) n" L  o& y. _  v
( x1 ~% d7 [4 ?: _
Our bodies use different types of tissue-specific stem cells to fit a particular purpose. Tissue-specific stem cells are limited in their potential and largely make the cell types found in the tissue from3 Z' y* }9 ?' E0 N8 W
which they are derived. For example, the blood-forming stem cells (or hematopoietic stem cells) in the bone marrow regenerate the blood, while neural stem cells in the brain make brain cells. A neural stem cell won’t spontaneously make a blood cell and likewise a hematopoietic stem cell won’t spontaneously make a brain cell. Thus, it is unlikely that a single cell type could be used to treat a multitude of unrelated diseases that involve different tissues or organs. Be wary of clinics that offer treatments with stem cells that originate from a part of the body that is different from the part being treated.+ E7 G/ p# n! j8 J, I6 E  B- p% [

2.  A single stem cell treatment will not work on a multitude of unrelated diseases or conditions.
干细胞疗法并不能实现“一石多鸟”
As described above, each type of stem cell fulfills a specific function in the body and cannot be expected to make cell types from other tissues. Thus, it is unlikely that a single type of stem cell treatment can treat multiple unrelated conditions, such as diabetes and Parkinson’s disease. The underlying causes are very different and different cell types would need to be replaced to treat each condition. It is critical that the cell type used as a treatment be appropriate to the specific disease or condition.

Embryonic stem cells may one day be used to generate treatments for a range of human diseases. However, embryonic stem cells themselves cannot directly be used for therapies as they would likely cause tumors and are unlikely to become the cells needed to regenerate a tissue on their own. They would first need to be coaxed to develop into specialized cell types before transplantation. A major warning sign that a clinic may not be credible is when treatments are offered for a wide variety of conditions but rely on a single cell type.
, w: x; ]5 ~( _) t
3.  Currently, there are very few widely accepted stem cell therapies.
当今尚无可被广泛接受的干细胞治疗方案
The range of diseases where stem cell treatments have been shown to be beneficial in responsibly conducted clinical trials is still extremely restricted. The best defined and most extensively used is blood stem cell transplantation to treat diseases and conditions of the blood and immune system, or to restore the blood system after treatments for specific cancers. Some bone, skin and corneal diseases or injuries can be treated with grafting of tissue that depends upon stem cells from these organs. These therapies are also generally accepted as safe and effective by the medical community.9 h, n( v5 O& {; g3 c
2 U% F; m! c7 j/ R) ^6 R
4.  Just because people say stem cells helped them doesn’t mean they did.
有人声称干细胞“奇效”也许并不是干细胞的作用
There are three main reasons why a person might feel better that are unrelated to the actual stem cell treatment: the ‘placebo effect’, accompanying treatments, and natural fluctuations of the disease or condition. The intense desire or belief that a treatment will work can cause a person to feel like it has and to even experience positive physical changes, such as improved movement or less pain. This phenomenon is called the placebo effect. Even having a positive conversation with a doctor can cause a person to feel improvement. Likewise, other techniques offered along with stem cell treatment—such as changes to diet, relaxation, physical therapy, medication, etc.—may make a person feel better in a way that is unrelated to the stem cells. Also, the severity of symptoms of many conditions can change over time, resulting in either temporary improvement or decline, which can complicate the interpretation of the effectiveness of treatments. These factors are so widespread that without testing in a controlled clinical study, where a group that receives a treatment is carefully compared against a group that does not receive this treatment, it is very difficult to determine the real effect of any therapy. Be wary of clinics that measure or advertise their results primarily through patient testimonials.. T% b6 C6 |- `+ {8 l2 P" T/ h! e

5.  A large part of why it takes time to develop new therapies is that science itself is a long and difficult process.8 |/ ]% l7 B# e2 I
干细胞治疗目前仍是科学上的“悬而未决”
Science, in general, is a long and involved process. Understanding what goes wrong in disease or injury and how to fix it takes time. New ideas have to be tested first in a research laboratory, and many times the new ideas don’t work. Even once the basic science has been established, translating it into an effective medical treatment is a long and difficult process. Something that looks promising in cultured cells may fail as a therapy in an animal model and something that works in an animal model may fail when it is tried on humans. Once therapies are tested in humans, ensuring patient safety becomes a critical issue and this means starting with very few people until the safety and side effects are better understood.

If a treatment has not been carefully designed, well studied and gone through the necessary preclinical and clinical testing, it is unlikely to have the desired effect.  Even more concerning is that it may prove to make the condition worse or have dangerous side effects.

See How Science Becomes Medicine

6. To be used in treatments, stem cells will have to be instructed to behave in specific ways.
让干细胞起效还需开启“效应窗口”
Bone marrow transplantation is typically successful because we are asking the cells to do exactly what they were designed to do, make more blood. For other conditions, we may want the cells to behave in ways that are different from how they would ordinarily work in the body. One of the greatest barriers to the development of successful stem cell therapies is to get the cells to behave in the desired way. Also, once transplanted inside the body the cells need to integrate and function in concert with the body’s other cells. For example, to treat many neurological conditions the cells we implant will need to grow into specific types of neurons, and to work they will also have to know which other neurons to make connections with and how to make these connections. We are still learning about how to direct stem cells to become the right cell type, to grow only as much as we need them to, and the best ways to transplant them. Discovering how to do all this will take time. Be wary of claims that stem cells will somehow just know where to go and what to do to treat a specific condition.

7. Just because stem cells came from your body doesn’t mean they are safe.: R4 s8 q( h% h# C+ r6 r2 B
用你自己的干细胞也不一定就安全
Every medical procedure has risks. While you are unlikely to have an immune response to your own cells, the procedures used to acquire, grow and deliver them are potentially risky. As soon as the cells leave your body they may be subjected to a number of manipulations that could change the characteristics of the cells. If they are grown in culture (a process called expansion), the cells may lose the normal mechanisms that control growth or may lose the ability to specialize into the cell types you need. The cells may become contaminated with bacteria, viruses or other pathogens that could cause disease. The procedure to either remove or inject the cells also carries risk, from introducing an infection to damaging the tissue into which they are injected.

8.  There is something to lose by trying an unproven treatment.1 f8 _, p9 a0 f% |
未经证实的疗法令绝望的病人更加绝望
Some of the conditions that clinics claim are treatable with stem cells are considered incurable by other means. It is easy to understand why people might feel they have nothing to lose from trying something even if it is unproven. However, there are very real risks of developing complications, both immediate and long-term, while the chance of experiencing a benefit is likely very low. In one publicized case, a young boy developed brain tumors as a result of a stem cell treatment. Participating in an unproven treatment may make a person ineligible to participate in upcoming clinical trials (see also number 9). Where cost is high, there may be long-term financial implications for patients, their families and communities. If travel is involved there are additional considerations, not the least of which is being away from family and friends.

9. An experimental treatment offered for sale is not the same as a clinical trial.
让病人交钱当“大白鼠”不是真正的临床试验
The fact that a procedure is experimental does not automatically mean that it is part of a research study or clinical trial. A responsible clinical trial can be characterized by a number of key features. There is preclinical data supporting that the treatment being tested is likely to be safe and effective. Before starting, there is oversight by an independent group such as an Institutional Review Board or medical ethics committee that protect patients’ rights, and in many countries the trial is assessed and approved by a national regulatory agency, such as the European Medicines Agency (EMA) or the U.S. Food and Drug Administration (FDA). The study itself is designed to answer specific questions about a new treatment or a new way of using current treatments, often with a control group to which the group of people receiving the new treatment is compared. Typically, the cost of the new treatment and trial monitoring is defrayed by the company developing the treatment or by local or national government funding. Beware of expensive treatments that have not passed successfully through clinical trials.& o4 q7 C0 ~: p3 T* w; i! B3 r( n

Responsibly-conducted clinical trials are critical to the development of new treatments as they allow us to learn whether these treatments are safe and effective. The ISSCR supports participation in responsible clinical trials after careful consideration of the issues highlighted on this site and in discussion with a trusted physician.

10. Stem cell science is constantly moving forward.
科学家对干细胞的认识尚处在“幼稚期”
Stem cell science is extraordinarily promising. There have been great advances in treating diseases and conditions of the blood system using blood-forming stem cells, and these show us just how powerful stem cell therapies can be. Scientists all over the world are researching ways to harness stem cells and use them to learn more about, to diagnose, and to treat various diseases and conditions. Every day scientists are working on new ways to shape and control different types of stem cells in ways that are bringing us closer to developing new treatments. Many potential treatments are currently being tested in animal models and some have already been brought to clinical trials. In February 2010 the British company ReNeuron announced it had been approved to conduct a Phase I clinical trial of a neural stem cell treatment for stroke. The first embryonic stem cell-based treatment for acute spinal cord injury has been authorized by the U.S. Food and Drug Administration (FDA) to move into Phase I clinical trials. Although it is sometimes hard to see, stem cell science is moving forward. We are tremendously optimistic that stem cell therapies will someday be available to treat a wide range of human diseases and conditions.# }" l; X- H3 ?+ T0 @

Top 10 Medical Myths and Lies. #8: Stem Cell Treatments for Terminal Diseases are Available in Foreign Countries
引自：http://thealzheimersdoc.com/?p=816
Posted on April 12, 2011 by Dr Ken Romeo ( W3 b( f; [/ k) p% e
There’s a conman born every minute and giving false hope to a terminally ill patient by offering a bogus medical procedure is a crime of the worst order. Many people have been conned into mortgaging their house, borrowing money from their friends and selling other valuables in schemes that are designed to part dying people from their money. It’s criminal.5 f! i& V+ l, H) H3 x& {  g5 f
8 Q; z7 d" o4 N5 D
At the time I researched this post (Winter, 2010), there were no legitimate stem-cell therapies for sale anywhere on planet Earth. If you hear about anyone claiming to cure anything with stem-cells, it’s probably a scam." s7 v( q/ \$ Q5 V
( A& H3 v4 j# u  U$ y. n
Stem cells are a very real avenue of research and may in time offer potential treatments and even cures for many diseases. The thought that we can replace dead or dying cells with healthy new cells is a dream-come-true and may someday treat many diseases like Alzheimer’s and Parkinson’s disease. But the fact is that science isn’t there yet and legitimate stem cell treatments are not available to the general public.4 ?8 C5 t" g( G% o" y+ r1 y

Medical science is only now beginning to make the transition between animal research to the earliest human research with stem-cell therapies. The only stem-cells that should be given to humans should be done in a legitimate and ethical experimental protocol and not in some clinic in China, Mexico or Buenos Aires.

Example: There are literally thousands of cancer cures that are promoted on the Internet. These “cures” are usually promoted based on the “conspiracy theory” that there is a code of silence in the government and medical community about cheap methods to cure diseases. For some reason we believe that the government and most physicians are “in” on this conspiracy. This simply isn’t true.

When all is said and done, what these “stem cell marketers” are trying to do is to sell you the myth of a secret cancer cure. This is very dangerous because this type of scam lures many patients away from proven and legitimate medical therapies—therapies which may even have a potential for a cure in some cases for some types of cancer. If nothing else, these legitimate therapies may extend the duration and quality of life in some types of cancer for many people.. [$ L: s% j+ B1 M9 J

Bottom line: Don’t get taken in by conmen. The science of stem cells is just too new and we are only beginning to experiment with human applications.

干细胞治疗某些特定的疾病是绝对有效的，没有必要全盘否定吧，没有看到没有了解到的事实，不代表不存在。截至2010年10月18日，在美国国立卫生研究院正式登记的干细胞治疗临床试验有3248项，其中基于成人干细胞的治疗方案超过73种疾病，包括1400项FDA批准的临床试验。我国2010年相关干细胞研究的经费达30亿。造血干细胞移植治疗白血病、上皮干细胞治疗烧伤和角膜疾病已经有成型的临床标准，虽然干细胞临床治疗的路很长，但相信很快很快我们会迎来干细胞临床应用的春天。 @6 P1 X% M. A7 _7 S: P' ?

不知道你有没有看2011年的863的指南。其实很多临床研究是在国家的一些大项目的指导下完成的。
以浙江为例，5家三级甲等医院参加了临床的研究，包括浙大一附院、二附院、邵逸夫医院等一流的医院。
确实有不规范的，但不能因为有不规范就否定一切。, B9 l* L" D7 t$ }! T% ~
如果干细胞研究仅仅只能是基础，永远用不了临床，那他还有多大的意义呢？我相信你也是在研究干细胞的，你的目的是什么？难道不是为了有一天干细胞的研究可以造福人类？) f u' v) |. k3 E( P6 r
我们都是在摸索，没有尝试永远也就没有进步。: J" k) _" q# A

不知道你知道不知道青霉素应用的历史，刚发明的时候反对的声音有多少，可后来又救了多少人！

我努力我凭心我无悔！

人间正道是沧桑，人类发展史也是一部与疾病抗争的历史，随着文明程度的提高大面积传染性疾病和多数急性疾病已经得到有效控制，与发现和发明青霉素、磺胺、阿司匹林、无菌手术的那个时代的状况完全不同，现代医药研究重心转向了重大难治性疾病，目标是生存质量而非生存率。

干细胞技术将继现代药物和手术治疗之后掀起一场新的医学变革，为一些重大难治性疾病提供崭新的解决方案，但干细胞技术是一把“双刃剑”，人类已经在疾痛中等待了数千年，操之过急势必带来一场人道主义灾难，阻碍干细胞技术的发展。# n% y t( X; A8 j% n

我国有关部门已经开始着手研究并提出制度性文件草案和相关技术标准、规范，探索建立适合我国的干细胞临床研究和应用监管模式和长效机制，大家还是稍安勿躁，相信面包会有的。

干细胞不是万能的，但却在一些病人中有一定的作用，不要一棒子打死，谁能说造血干细胞治疗白血病是不合理的呢# l8 ]2 x# N. @9 P5 U

其实骨髓移植就是一种干细胞移植，相对来说非常成功

有机会接触过某获批干细胞药品，如之前几位同学所说，从循证医学的角度来看确实比较缺乏证明其有效性和安全性的数据支持，但从个案来说确实是有一定效果的。原文中的某些观点我认为并不是专业人士写出来的。而是带有某种倾向性。我们是不是可以从医学最基本的原则：“风险收益比”的角度来考虑这个问题，也就是说，如果某种方法是对于特定病人来说是收益大于风险的，那么就应该去使用它。反正则应谨慎。最后，再次呼吁国内相关规范能早日出台，使这个学科能更加健康有序的发展。
