来自主题: Automobile版 - Reprogram PCM 只能去dealer做吗?
去修车,被告知要reprogram PCM,他们那做不了,要去dealer那做。我上网查了下
reprogram pcm,网上有很多讲如何DIY的,说以前设备只有dealer有,后来因为什么法
案,这个必须要public,所以现在我们可以diy了。既然这样,那修车的店应该也能买
到啊,问了好几家修车店,都说不行,dealer又死贵,哎。

请教一下carfax熟悉的同学, 我最近查了几个车的记录, 有的车有有保养的记录, 有的
没有. 请问没有是正常的吗? 有记录的车那些记录是完整的还是有的有,有的时候没有?
另外一个车的两次保养记录都包括Computer reprogrammed, 还有GPS/Navigation
module/computer reprogrammed, 这属于正常保养范围还是说这个车ECU老有问题需要
program?

新买的遥控器,电池也是新的。按照说明reprogram了,最后按了lock以后,门也自动c

但是遥控器上没一个钮工作,如果receiver坏了前面reprogram应该不会成功吧?按了l

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

Thank you.
Lineage reprogramming is definitely very promising. As mentioned in another
post, it has been showed that fibroblast can be transformed to neuron
with only 3 TFs.
At the same time, direct programming from ES/iPS cells to somatic cells are
few. And I was not be able to find any publications. So was wondering if
someone can help me with some papers about direct programming from ES/iPS
cells to somatic cells with TFs, not stepwise extracellular signals.
Thanks.

These are good questions! I also thought about that.
Theoretically, directional differentiation is easier than reprogramming,
because the latter is not a natuarl process. There is no any reason that
transcription factors should not force cells to differentiate into specific
lineage, given the facts of iPS.
I don't think any lab has achieve this, though.

这篇文章的发现固然有意思,但是能发在nature上也有赶潮流(反潮流)的因素在里面
。这篇文章的意义在于提醒人们不能忽视移植受体对iPS细胞可能存在的免疫排斥,但
是由此就把iPS一棒子打死也不免言过其实。
对于iPS细胞能否用于及时有效的器官移植,大家一直有争论。免疫排斥不论,另一个
很大的问题是及时性。毕竟很难想象在急需移植器官的时候,病人能够等待至少6个月
以上的时间,以便从体细胞开始reprogramming并生产出数亿个特定的功能细胞(器官
移植需要末端分化的细胞,否则有致癌的危险)。一个解决办法是利用胚胎干细胞,进
行所谓的预生产,这也是目前进入临床试验的两个项目(Geron的脊髓损伤和ACT的
Macular dystrophy)都利用胚胎干细胞的原因。
另一个解决办法是建立iPS Bank,在目前无法建立新的ESC系的情况下,建立尽可能多
的iPS系,理想状况是囊括所有人群。很多大的医药公司也希望建立这样的iPS bank,

因为我曾经在一个iPS group边上,所以比较关心iPS这方面。
在yamanaka之前,有这样的观念,用1-2个cDNA transformation,然后得到什么什么细胞系
这个本质是stable cell line和transgenic 路数
iPS 开辟的是reprogramming这个路线,在iPS之后,马上很多人就做了
transdifferentiation,依据同样的思路。
在Yamanaka之前,有些人搞过这个XXX细胞到iP,比如Stanford 胡继繁就有类似的想法,还申请了
专利,但毕竟没有成功。
当然,iPS有很多要细化的研究,比如gene deletion duplication trouble in the final iPS
iPS generated from somatic cell? or from few tissue stem cells in the
primary culture???
无论如何,这个是reprogramming的事情,是的,某些伙计说的,或许弄出了生物学有
史以来最大的reprogramming 泡沫,呵呵

Induced pluripotent stem (iPS) cells can be generated using retroviral

required multiple retroviral vectors for reprogramming, resulting in high
numbers of genomic integrations in iPS cells and limiting... 阅读全帖
