Hmm. If anyone can suggest a better title (i.e. more accurate and neutral, preferably using representative language from the article), we can change it again.
From the article they specify "with Klinefelter syndrome" which is the XXY version of trisomy 23. This fits the word limit: "Scientists generate XX and XY cells from a person with Klinefelter syndrome"
Ok, let's go with that. Thanks!
None of us will have heard of Klinefelter syndrome before, but maybe that's a good thing.
