Synthetic life without sperm or egg

https://nature.us17.list-manage.com/track/click?u=2c6057c528fdc6f73fa196d9d&id=749058c905&e=16e19f6d04

Natural and synthetic mouse embryos grown by developmental biologist Magdalena Zernicka-Goetz’s research group.

Two research groups have developed mouse embryos “In vitro” from stem cells. They have lives of 8 1/2 days out of a 20 day gestation period. They also face a challenge of getting beyond the 11 day hurdle without a placenta.
This would allow a lab to not have the need for animals from outside sources to test with since they can be grown in house.
The fact that two groups replicated results validates the process. Good research is always replicated by a second group.
This also leads to cures for humans and there is a 14 day rule on human stem cells currently in regards to ethical practices.

Even if it's managed to stop it in this country your not going to stop it in countries like China or even Russia for that matter.

It pretty well known the Chinese have little moral values regarding this. They have already done DNA manipulation itself.

Crisper has opened up so many possibilities for genome editing. I think I heard of other rumors that there were secret excursions in this new science.
I didn’t find that on the internet though recently.

@Pfuzylogic the article went on to say this in the next paragraph...

Scientists in China who are currently researching CRISPR for its potential to treat various genetic diseases by modifying cells other than embryos say that they fear He's actions might have a chilling effect on their work, too, even though it is not as ethically fraught.

Notice what they don't say. It doesn't say they have stopped!

Xi Jinping is beholden to no one.
I am certain it only takes his word to allow anything.

Very interesting with a plethora of potential positive developments. The trick is how do we keep further applications in the hands of people only wanting to do good for mankind...

@Pfuzylogic Agreed. It's an admirable cause. Not sure how we do it though..

@Majorlatency
Just like everything else at least in my country…legislation. Who knows maybe there will be an international council.

Majorlatency · M

@Pfuzylogic Yes it has to be unilaterally supported by an international council. One country cannot do it alone..

Have a great weekend..

I saw a reference to this yesterday in my alumni newsletter https://www.nature.com/articles/d41586-022-02334-2

I started reading the article, but not done with the detailed references. One of a half dozen or so projects nearing fruition, to produce organs with no need for a human donor.

@Northwest
I do get the Nature newsletter.
I pulled this from there.
You will notice in my post the link in quotations.
This is not for human organ transplants even though that might be a future aim.
It is simple using stem cells to skip the conception process which in and of itself is a first of kind.
It is also good to see the process replicated, many times that will be skipped because of cost and claims will be made that shouldn’t be!

I am a Christian and so far I am tentative with the methods. I am concerned on how this will be treated with humans.

@Pfuzylogic i like the idea .. the idea of growing body parts is great and even life itself would be great .. a clone of a person is one that is been around in fiction a long time.. this is interesting.

@markansas
The Christian adheres to the concept of soul and the dignity of life. I am quite certain that laws will be created that guide ethical practice. I do understand that there are countries that do not go by any guidelines.

This also leads to cures for humans and there is a 14 day rule on human stem cells currently in regards to ethical practices.

honestly my first thought was that they are trying to make a way for transgender to become pregnant.

@Chickie
I can see that being related but being “in vitro” it is outside of the body! So many ways that beliefs are being enabled by technology.

Chickie · F

@Pfuzylogic technology is rapidly advancing and it's scary to what we can do now. Playing God never turns out right

Pfuzylogic · M

@Chickie
I agree with your idea that playing God can have some very strong their consequences. It is just like developing the Internet but now we are applying technology to lives.
