Could you clarify what you are trying to achieve with this comment? I work in a related field and talk to stem cell/organoid growers from time to time.

It is in fact hard to grow brain organoids from stem cells; this is still very much a thing that requires expert hands and minds to do effectively.

Unfortunately I'm not able to validate the second point (that the results of the research made a new technique for growing brain cells) because the paper is very technical in ways I'm not an expert.

No one but you said "non important."

How do you have such stunning confidence that you're replying to someone who knows 'nothing about' the subject matter? Maybe he's a neuroscientist.

I think YOU are the one showing stunning confidence in something you know nothing about (op's area of expertise. Unless you know them personally. Then ignore me).

easy there:)
