This is kinda cool, especially if they can start growing other organs as well.
I noticed this news article today as well. However, after reading it and seeing that there is no publication reference I denounced it (I'm not saying it's not done but I wond go further into details about the work). If there would have been a journal article to reference to I would look further into the work. However, since there is no article reference, a person can't read up on the work and check for flaws in the study design, ethical concerns and so forth.
