基础。有的也有药监局批准。所以比电线杆小广告水平要高是没问题的。之所以这种治
疗比美国开展的要深入还有一个重要原因可能你有所不知，就是很多这种干细胞来源是
流产胚胎，在美国是得不到这种材料的。至于成瘤性风险，用胚胎组织干细胞风险要比
用embronic stem cell要低的多。对患者本人来讲跟他讲明利害关系，如果他和家属都
愿意承担风险的话，签双向同意书。现在手术前不都这么做的么。太普通不过的程序了

stages?
It would be great if you can share me some experiences.
Bests! |

发帖数: 47 | 3 Please list a few, not limited to any specific organs or tissues. This is
good for looking for a hot or becoming hot area to work in next few years.
I start first. Of course, it is debatable depending individual opinions.
1. stem cell related research (cancer stem cell, embronic stem cell,
hematopoietic stem cell, IPS, what ever): I feel it is not gonna be
extremely hot in next few years, but still hot.
2. Epigenetics, especially to understand how the Chromatin modification
regulators interact w |

能够成为抗原，因为免疫系统首先要避免攻击自身。也并不是非要突变才能形成肿瘤抗
原， immune privilege sites, embronic develpoment specific gene的异常表达，
都可形成肿瘤抗原。可以说，肿瘤本身并不缺乏抗原，缺的是一个形成免疫反应的环境。
NK cell mediated Killing, Antigen spreading, 都可以解释你的第二个问题。建议
你看看参与免疫反应的各类细胞，以及免疫反应的各个阶段和逐级放大的过程。

In radiation protection, the fetus is considered more vulnerable to
radiation than an adult because more embronic cells are proliferating and
differentiating than adult cells in a given volume, especially in the first
trimester. |
