Function

Kupffer's vesicle is not only required for normal asymmetric development of the viscera, but also that in the absence of fgf8, this ciliated organ directs aberrant asymmetric development of the pharyngeal skeleton ( 15932752).Fgf8 and Fgf24 both signal through FGFR1 to maintain normal cilia length. Loss of both causes pronounced shortening(PMID: 19242413).
