A new ‘rotational’ twist in an old tale: mammary epithelial cells ‘weave’ a laminin matrix as they rotate during acinar morphogenesis.
Single mammary epithelial cells are capable of regenerating complete mammary gland structures when given the right stimuli. Mammary tumor cells however, are incapable of this. In a suc... |
