the second story really hits me hard. I was born with a malformed valve that wasn't opening properly through most of my life. I had to get a lot of procedures done and I really wasn't properly informed about all of it and why it had to be done till my final operation came and the doctors sat me down and told me they were going to stop my heart, open my chest and fix my heart valve. Till that day my parents had kept me in the dark. It was a case of "we say so so that's it". I finally had a stint put in place to basically prop the valve open.

As a stem cell biologist, I think the bioreactor used as artificial wombs can also be truly revolutionary for stem cell biology. Over the past years, so-called organoids have been generated which mimic parts of an organ. We can grow organoids from stem cells (which can be made from skin) and then use them to study development. For example, brain organoids helped to understand how the zika virus lead to a brain disease called microcephaly in embryos and how schizophrenia forms (I made a video about this). The thing is the larger an organoid gets the more issues we get with oxygenation so this new bioreactor could help!

[@kamashigamisho]

"Revolutionary" hmm.. I see what you did there!!

Not even just that but like with the heart valve story I bet it could help in the study of growing replacement organs from a persons own stem cells.

Cool perspective!

[@missink1728]

Have you heard of crispr? It's a method of copy and pasting DNA that was developed by studying bacteria that take virus DNA and cut and paste it into their own DNA so they can recognize it later on. If an organ had a genetic problem, crispr could be used to specifically correct the problem in a person's DNA.

So, it's not how an animal is birthed, but the actual characteristics of said animal. #themoreyouknow

For anyone interested in artificial wombs take a look at the Vorkosigan Saga. It's a really good science fiction series where one of the big technologies is the uterine replicator and it takes looks at the good the bad and the horrific implications. Just two examples: One of the main characters survived because he was transferred into a uterine replicator after a catastrophic event happend to his pregnant mother The ruler of a district sets up a baby making factory to try to counter his districts demographic problems. Every single one of which is his own genetic daughter

Technology like this could finally put an end to the abortion debate. If a woman doesn't want to carry a fetus to delivery, she can sign away all rights to the fetus and have it removed from her and placed into an artificial womb to finish development. In fact, I think this tech would be so popular with working women that it'll eventually become the norm to transfer the fetus to an artificial womb at some point.

After the development is finished, who'll own the child?

How cool! We could potentially use this for people whose uteruses had damage or complications or people who don't have uteruses and let them have kids without the use of a surrogate mother. This is also a lot safer for those who had multiple C-sections. I look forward to our advancements in this area.

I just recently had open heart surgery to replace my valve. I wonder what it would have been like to have it done as a child and have a valve that grew with me into adulthood? Something that wouldn’t need to be replaced in another fifteen years. Something that meant I didn’t have to take Warfarin every day and constantly go for checkups, echocardiograms, monitors, and the like. Good luck, future kids! I wish you all the best ❤️

[@igkslife]

To temporary fix the 11 day problem, your going to basically need a second artificial uterus. Because in the first 9, or so days the embryos are basically cells in a incubator, but once they get to a certain point they need to start receiving nutrients directly into the developing stomach. That's why they attach themselves to the walls of the uterus to begin with during a certain point in their development. So, a 2 uterus system will be needed. Next the heart bit, well I hope it can work on me to be honest.

[@gislaw1324]

Oh wow! The artificial womb stuff is super cool! I’m excited to see where it goes and I do hope it becomes something we can do. I want to have kids, but actual carrying isn’t a great plan and surrogacy is risky. If this becomes available I definitely would be interested.

I'm pretty sure that the sticking problem - which they solved here by continuously rotating the jars containing the gestating embryos - has an alternate solution which may prove more adaptable to growing the foetuses of larger organisms. Keeping box jellyfish, with their fragile gelatinous bodies, in captivity for experimentation is difficult as they tend to get severely damaged by repeated impacts with the aquarium walls. Researchers developed a specialised system, with a rotating current that hugs the curved walls to deflect the tiny jellies before they can make contact - in effect keeping them corralled with water. So instead of rotating the container, you produce a sustained current that prevents the growing embryo from adhering to the container walls. This could also be used to introduce nutrients & oxygen to the growing embryo in a relatively controlled manner.

I'm curious what people think the "ethical questions" would be regarding human and animal artificial womb usage. We often only question something when it diverges from the status quo, no matter how bad the status quo may be. What of the ethical question of subjecting women to the lifelong health issues of pregnancy, the societal issues of not being able to even secure reproductive or even personal healthcare due to conservative/religious politicking, the fact that humans in both the post-colonial plantation nations and the developed world have an unsustainable level of resource usage and environmental destruction at their current levels, and the fact that-- whatever people may posture --any random individual human life is objectively not treated as important by the consequentiality of our societies. Humans will only ever rise to the level of what we pretend and dream ourselves to be when birth is completely an informed choice that isn't almost entirely a case of accident.

[@evilsharkey8954]

It seems like the lack of an umbilical cord is a pretty major limiting factor in developing embryos outside of true womb. There has to be a way to provide nutrients and extract waste. They’ll have to figure that out if they want to be able to grow viable organisms.

[@Kabup2]

embryos make the placenta, who make the umbilical cord. You just have to provide the uterus.

[@evilsharkey8954]

KaBup, the placenta has to have something to exchange with. In the womb, the placenta and uterus tissue are highly intertwined, with a lot of surface area for nutrient, waste, and gas exchange.

[@Ludens93]

The valve story is heartwarming. I think we still have a ways to go on ectogenesis though.

[@silverhands1088]

Two things to note: Outside of the heart, arteries do not have valves, but veins have them. Removing cells from the valve matrix reduces the chance for an immune response at this matrix. Transplant drugs that temporarily prevent the immune system from attacking the valve while host cells migrate into the valve further reduces the probability for rejection.
