2007IBM全球CELL BE校园大赛的最终榜单于近日揭晓:由我校电子信息与电气工程学院、生命科学技术学院、微电子学院的同学所组成的两支团队,从全球93支高校团队中脱颖而出,分别夺得欧亚赛区第一名和第三名的好成绩。
由IBM 、索尼和东芝共同开发的基于Power架构的Cell宽带引擎(Cell Broadband Engine,简称Cell BE),以其突破性的多内核架构和超高速通信功能可以有效提供“超级计算机般的性能”,特别适用于许多行业的高性能工作负载,包括数字媒体、医疗图像、航空航天、国防和通信行业。2006年,美国能源部国家核安全管理局(NNSA)选择由IBM来设计和制造世界上第一个采用Cell BE处理器强大处理能力的超级计算机,目标是制造一台能够持续以最高每秒钟1000万亿次计算(1 petaflop)的持久速度运行的计算机。也是在2006年,中国科学院计算机网络信息中心和IBM在中国科学院网络中心签署协议,双方宣布将在中国国家网格(CNGrid)上提供基于Cell BE的刀片服务器计算节点,为中国国家网格用户在模拟仿真、图形可视化、图形渲染、图像及多媒体处理等应用领域提

this Nature paper (2002 417:39) addressed the mechanisms that
control fate of neural stem cells. astrocytes have been
thought merely as supportive cells in the central nervous
system, however, this work has demonstrated that astrocytes
isolated from adult hippocampus, but not spinal chord,
promoted neurogenesis (i.e., neuron fate) of the adult neural

Pluripotency and Totipoteny has similar meaning if not the same, i.e.
differentiation potential of all lineages but not SC of all different cell
types. But some ppl prefer to use Totipotency for ESC.
As I mentioned before, some of the adult stem cells are NOT true stem cells,
coz they only have limited self-renewal ability and differentiation potential.
So it's probably more approtiate to call them progenitor cells. Most time the
Sci would like to blow they find xxx type of stem cells, however,

来自主题: Biology版 - Harvard stem cell paper retracted
Several different concepts are being discussed here:
1. The origin of tumor/cancer(single cell or multiple cells)
2. The existence of CSC. Even if the tumor origin is only one cell (
differentiated or tissue-specific stem cell), the whole tumor is
phenotypically heterogeneous, which has been proven by many many
experiments
. Then do all these cells have the same potential to initiate a new tumor?
Or to be more practical, do all these cells have the same potential to met
or relapse after chemo?

来自主题: Biology版 - 再次请教cancer stem cell
Good point.
My guess is that within a tumor or even cell line, there is always a
population of cells with better tumorigenesis potential / drug resistance.
Even if you get rid of those cells, other cells will replace.
Since cell lines are supposed to be genetically identical, epigenetics might
play a role here. It would be very interesting to identify the factors
involved in generating such population of cells.
And in terms of curing cancer, personally speaking I think too much focus

I was asked a question whether it is meaningful to search the cancer origin

Actually, I found that I have no answer after taking more thought about it
and why I am doing it. So I open it for more discussion:
The promoter driving Kras is SP-C, active in both clara and type II cells.
I get myself into it because of Carla's finding on the stem cells. Since I

By ectopic expression of only 4 transcription factors, terminal
differentiated somatic cells can be transformed to be iPS cells. My question
is that if iPS cells or ES cells can be directly programmed to a specific
somatic cell fate by a pool of lineage specific transcription factors
without usually used stepwise protocols. If yes, could you please show me

All science students learn the 'central dogma' of molecular biology: that
the sequence of bases encoded in DNA determines the sequence of amino acids
that makes up the corresponding proteins. But now researchers suggest that
human cells may complicate this tidy picture by making many proteins that do

1) If Cell phone radiation is beyond a certain/unknown threshold, it
will
hurt users or cause cancer in a long-term usage model.
2) Mostly the current cell phone radiation may not be strong enough to
reach that threshold.
If this is the case, I guess it is about defining the threshold.
BTW, is epidemiology the only area we should look at?

I guess you don't have much background of cell therapy. So far, only the
therapy with the Y-chain recovery in stem cell is oncogenic, and the main
reason is because strong signal of Y chain itself induces lymphoma instead
of the viral integration. For all the T cell or DC therapies which have been

你说的比较温和是指什么?
来源于很多组织的人的fibroblast可以通过overexpress hTERT得到immortalization,
这是由于人的fibroblast在体外培养条件下的senescence多是由于端粒渐行缩短而导致
的(telomere-dependent replicative senescence)。与人的fibroblast不同,体外
培养中MEF的senescence并不是由于端粒缩短引起的,而是由于如前所述的过氧基团累积
oxidative stress induced DNA damage。研究表明senescence的MEF的端粒还很长,而
且MEF中有较高的mTERT表达,所以过表达mTERT并不能有效immortalize MEF。因为要抑
制p53和Rb通路,所以表达异源的SV40 T和HPV16 E6/E7都可以immortalize MEF。当然
这样得到的细胞株,由于这些病毒蛋白的过量表达,基因组并不稳定,长久培养会出现
嬗变。

来自主题: Biology版 - 关于stem cell marker的筛选的设想
对的,很多研究单纯就靠几个所谓marker的表达水平来鉴定stem cell identity确实不
可行。
lineage tracing不完美,比如leakage等问题。不过已经是当前能做到的最好的了。依
然该是金标准。
没有一个marker是完美的。比如alexandra joyner的那篇关于GLi1+ cell作为hair
follicle stem cell marker的文章。单纯从lineage tracing结果来看其实并不完美,
其对hair follicle的contribution并不完全,但是重要的是他们揭示了这群gli1+
cell是受神经分泌的Shh的调控的。这就重要了。marker不是目的,找到一个marker就
意味着一个in vivo model的建立以及一个可能的新的regulatory mechanism.

来自主题: Biology版 - 关于stem cell marker的筛选的设想
经典的干细胞理论模式和定义基本都是来源于HSC的研究,单个HSC以一种hierachical
的方式逐级重建整个H-lineage 。也由此self-renewal,multipotential 成为干细胞的
定义。
但实际上别的organ的干细胞并非如此。self-renewal是当然的。可multipotential 这
可真未必了。unipotential的就不能叫stem cell? 我认为这个定义需要修改。实际上
在现在很多stem cell研究里multipotential已不再是评价指标之一了,尤其在lineage

式去做过研究吧。我对HSC知道不多.
