Morphological and biochemical analysis of Rac1 in three-dimensional epithelial cell cultures.


Rho GTPases are critical regulators of epithelial morphogenesis. A powerful means to investigate their function is three-dimensional (3D) cell culture, which mimics the architecture of epithelia in vivo. However, the nature of 3D culture requires specialized techniques for morphological and biochemical analyses. Here, we describe protocols for 3D culture… (More)
