Wow, on the top list!
Well, I never expect to be on the top list. This reason is that I am not
here very often. Also apologize to those are discussing about the topic and
expect me to give my opinion.
I believe that the previous title regarding to someone retract her paper is
misleading. So it is necessary to clear some issue and have an opportunity
to draw more discussion. Now back to the stem cell issue not the Amy or

ScienceDaily (July 9, 2011) — For the past decade, researchers have tried
to reprogram the identity of all kinds of cell types. Heart cells are one of
the most sought-after cells in regenerative medicine because researchers
anticipate that they may help to repair injured hearts by replacing lost
tissue. Now, researchers at the Perelman School of Medicine at the
University of Pennsylvania are the first to demonstrate the direct
conversion of a non-heart cell type into a heart cell by RNA transfer... 阅读全帖

Expanding on previous research providing proof-of-principle that human stem
cells can be genetically engineered into HIV-fighting cells, a team of UCLA
researchers has now demonstrated that these cells can actually attack HIV-
infected cells in a living organism.
The study, published April 12 in the journal PLoS Pathogens, demonstrates
for the first time that engineering stem cells to form immune cells that
target HIV is effective in suppressing the virus in living tissues in an
animal model, sa... 阅读全帖

Thank everyone for the discussion!
As pineseed pointed out, too many topics were discussed here.
But my personal interests are:
1. what is the cell origin of different type of lung cancers?
2. does cell origin or mutation decide tumor types?
3. how to model different type of lung cancer?
HGTPase, it seems you are working in this field (more lung development than
lung cancer?), and I hope you can give your opinions. We can also discuss in
private mails for technique details.

Abstract
Many cellular processes are regulated by cell cycle dependent changes in
protein dynamics and localization. Studying these changes in vivo requires
methods to distinguish the different cell cycle stages. Here we demonstrate

那个Structure不是Cell真正的子刊来的(意思是由Cell Press代出版,但不是Cell自
己主办的杂志)。
Cell Press的杂志和Nature一样,也有2种,一种“嫡系”(自己主办)的,就像
Nature里面nc,nn,nm,ni,ncb,nsmb等等这种。另一种是“旁系”(代理出版)
的,比如Nature里面的中国人搞的aps,cell research等等。
Nature系列好判断,只要某杂志前面带Nature,人人都知道,这是Nature的主力“中央
军”(Nature自己主办),是Nature真正的子刊。
Cell里面“中央军”(cell自己办的杂志,可以说是Cell真正的子刊)按首刊时间顺序
有Cell,Neuron,Immunity,Molecular Cell,Developmental Cell,Cancer Cell,
Cell Metabolism,Cell Host & Microbe,Cell Stem Cell ,以及最新的Cell

Solar shakeout continues: Q-Cells to file for bankruptcy

Q-Cells was once the largest solar cell maker in the world. Now the company

example of the solar industries’ turmoil.
The German company has been in trouble for some time and tried several cost-

实际上我觉得Pax7细胞就不应该叫做stem cell,

最近没事,看了几片beta cell的paper,
发现关于beta cell stem/progenitor cell的争论还挺热闹的。
顶尖杂志上经常你来我往灌水争论这个progenitor cell到底存在不存在。
04年Melton DA组的一片nature用了Insulin的reporter mice做了genetic tracing,说
新生的beta cell都是从existing beta cell长出来的,
但08年Xiaobo Xu的Cell比较清楚的证明了progenitor cell的存在,
11年3月的Simon R. Smukler的cell stem cell和说这个细胞是存在的,而且直接说
Melton当年nature paper里面的老鼠有问题。不过看了11年CSC的文章从submit到接受

实验嘛,不行就自己发明啦。
比如可以先回答cell contact是否required for somatic cell induced stem cell
proliferation.
可以把somatic cell先做你想做的处理,然后放在culture里,跟stem cell用0.3um的
膜分开。这样如果stem cell proliferation增加了,那说明是soluble factor,在
culture medium里面。可以尝试用不同的antibody block。这样可以找到是什么factor。
如果stem cell不增加,那么可以把stem cell用CFSE之类的marker标记了,和处理过的
somatic cell混养,这样如果刺激stem cell proliferation,那么说明cell contact
很重要。那么可以focus on cell surface molecules,试试不同的knock down,看看
有没有哪个能block这个过程。
当然,注意做好controls。

来自主题: Biology版 - 再次请教cancer stem cell
I guess these are two different concepts. CSC is to discuss if there are
some unique cells in the tumor that can self-renewal and give rise to
other tumor cells. The question you raised here is about the cell origin
of tumor, which is related with CSC, however not the same concept.Take a
look at this pape:
Crypt stem cells as the cells-of-origin of intestinal cancer.

I am talking about general cell therapy. Oncogenic is only one part of the
safety issue. For example, one major concern of T cell therapy is over-
activated T cell might cause autoimmune disease, which is a very common
problem in stem cell and organ transplant, including cancer immunotherapy.
Rosenberg, a big name in cancer immune therapy, killed one patient due to
the infused Her2/neu targeting T cell were activated in lung.

自己并不是做这块的,但有学生和我讨论起 Muse vs. iPS cells 的关系。
好像2011年的 一篇 PNAS 文章(http://www.pnas.org/content/108/24/9875.long)发现 human fibroblasts 的 iPS cells 主要是(还是就只是?)从 Muse cells 来的。
那么 Muse vs iPS cells 的现状是什么?
是不是所有 iPS cells 都是从 Muse cells 来的?还是 Muse cells 是其中的一个主
要来源,但其他 cell types 也还是可以变成 iPS cells 的?
麻烦领域内的大妞小妞砖家们给个简单的总结?
谢谢了!
