Figure 3: Defects in planar cell polarity results in cystogenesis. It is hypothesized that normal cilia function is required to control proper directional cell division. (a) Normal directional cell division is required to have an elongated tubular formation. (b) Disrupted directional cell division results in expanded formation of tubule.
