BREATHE EASY. SCI­EN­TISTS at the Uni­ver­sity of Michi­gan have used stem cells to grow self-or­gan­is­ing mini lungs, com­plete with the bronchi and alve­oli that are found in the hu­man or­gans. Though the lung struc­tures lack blood ves­sels, they rep­re­sent an im­por­tant step in mov­ing away from an­i­mal testing to more ef­fec­tive drug tri­alling and med­i­cal re­search, the team says.
