Bioengineers have shown great promise in creating complex multicellular kidney organoids (tiny, self-organized tissues) in the lab using pluripotent stem cells . They can further improve the procedure for different outcomes, ...
Inside a cell, tentacled vesicles shuttle cargo for sorting. DNA rearranges in the nucleus as stem cells differentiate into neurons. Neighboring neurons cling to one another through a web-like interface. And a new microscopy ...
