We're growing humans ?

No. These don't develop like embryos and do not have to come from embryonic stem cells.

The structures differ from real human embryos in many ways, and cannot develop into them because they lack several embryonic tissues, as well as the supporting yolk sac and placenta needed for further development.

The human stem cells used to derive hematoids can be created from any cell in the body. This means the approach also holds great potential for personalised medicine in the future, by allowing the production of blood that is fully compatible with a patient’s own body.

Perfect blood doping.

Kind of sad that that's the first thing that comes to mind...

Could you do this using current medicine by extracting and donating blood back to yourself after a week?

I'm pretty certain I read of people doing this in cycling tournaments.

Yes, Lance Armstrong did just that! https://www.usada.org/wp-content/uploads/ReasonedDecision.pd...

If that's what it takes get this technology everywhere i'm all for it lol.

An alternate Olympics where everyone is sponsored by medical companies :D

We have the Enhanced Games (https://en.wikipedia.org/wiki/Enhanced_Games), so we already have an alternative Olympics that definitely includes medical companies.

As if the un-enhanced games weren't already getting closer to playing a game of chicken with your health on the line.

I find it ironic that thats the first thing that comes to mind. I know people with rare blood groups, I think this could be huge for them.

I believe this could also be detected.

Yes, it would be exactly the same as the original, "crude" blood doping of injecting your own blood.

For people talking about "augmented games" and such, bear in mind that one of the reasons it was banned was that young athletes were suddenly dying a lot from heart problems.

We are not. These are embryo-like structures. Not actual human embryos.

they have no mouth even if they want to scream.

I'm an organ donor, and I have no problem giving my organs away after I'm quite positive I won't feel it. I think as long as there is no sensation, there is no pain, and certainly no formal concept of "self". But still, with matters of exploitation of our bodies, we should tread very very lightly.

that's an odd thing to bring up out of nowhere.

That's the technocratic endgame b/c a few people are rich enough to realize the potential for life extension using the same type of technology.

We've been growing humans since the beginning of time. This one is just in vitro.
