		<description>The problem with embryonic stem cells has always been two features of a cell started by meiosis - i.e. by the combination of an egg and a sperm cell.

First - as shown by Leonard Hayflick in the 60ies - there is a finite number of cell divisions that can occur without the resultant cell degenerating and fx. turning cancerous. In Hayflicks cultures it was 40-45 times. It is likely that some are genetical deficicient, so the number is much lower. This can be one of the reasons for cancers or other diseases hitting people before their &quot;use by date&quot; has arrived. An appendage to the DNA has been identified as the main? controller in this respect. That this is a problem can be seen in the short life of &quot;Dolly the sheep&quot; - where a.f.a.I.k they did not compensate for this.

The other major problem is immunologic. Each cell - apart from identical twins - is immunological different from any cell derived from another individual. This can be minimized, but NEVER eliminated.

Embryonic stem cells used in clinical experiments are different from the person they get implanted in. Hence the dismal results from the use of stem cells in among others parkinsons disease. 

This new research may eventually lead to better results without the problems noted playing a role. - and the ethical issues will be relegated to the question of how much we should interfere in the natural course of life - a much simpler and hopefully easier case for discussion.

peace

		<description>Right you are Lex, and put in that context it is a fair point that he makes. Thanks for the correction.

Now let&#039;s just hope this turns out to be a genuine result. This wouldn&#039;t be the first time some trumpeted about a great breakthrough in stem cells, only to have it turn out to be nothing.</description>

		<description>&lt;p&gt;Brian, you make a very important point on existing stores of embryos - one I agree with, even as I personally draw a queasy distinction between those embryos that were overproduced for fertility treatments and those explicitly created in order to be destroyed. I know they look the same, but to me at least they feel different.&lt;/p&gt;
&lt;p&gt;But  I think if you read Bottums again you&#039;ll find that his target was not so much the folks involved in doing research itself as folks like the editorial staff at the NYT whose pale enthusiasm for other uses of genetic science - as genetically enhanced crops, for example - does not match their ardor for human embryo research. He postulates their enthusiasm for the latter may be tied to their position on abortion. &lt;/p&gt;
&lt;p&gt;As I said, I think perhaps we&#039;ll see if he&#039;s right.&lt;/p&gt;

		<description>If this development pans out it is undoubtedly a great thing. It&#039;s undeniably better to not have to harvest these cells from embryos. 

However, as someone who did support embryonic stem cell research, I resent Bottums&#039; claim that it was all just a sham to protect abortion rights. The embryos used for that research were going to be destroyed one way or another -- none of them was destined to be born. Is it not better to at least derive some good from them, and perhaps make some people&#039;s lives better? And is that not enough reason to support that research?  

Bottums is essentially making an ad hominem attack on his opponents by questioning their motives, instead of addressing their arguments. It&#039;s a cheap rhetorical trick, on the same level as claiming that the Iraq war was ginned up to enrich Halliburton or &quot;for the oil.&quot;</description>

		<description>This has nothing to do with this post but I wanted to wish you and your family a warm and happy Thanksgiving. Like a lot of us, you have much to say thanks about. Now take another week off..</description>

		<description>Cap&#039;n, et al,

Lee, I, too, am sad to hear about your father.  The sort of hope this announcement brings may be too late for him, but others may well benefit.

What encourages me about this news (btw, there was an independent team here in Madison, Wisconsin) is that people suffering from Multiple Sclerosis (as I do) have another ray of hope.  I advocate the State Legislature on behalf of the many in this State suffering from MS.  Stem cells hold promise for us, but, like Lee&#039;s father, we likely won&#039;t see a cure anytime soon.</description>
