Nuclear positioning in the gonadal distal tip cells of C. elegans

Morphogenesis of the hermaphrodite gonad of Caenorhabditis elegans is directed by the U-shaped migration of the gonadal leader cells, which are called distal tip cells (DTCs). The nuclei of migrating DTCs are always positioned at the leading edge of the cells, even as these cells turn dorsally to co...

Sumario:Morphogenesis of the hermaphrodite gonad of Caenorhabditis elegans is directed by the U-shaped migration of the gonadal leader cells, which are called distal tip cells (DTCs). The nuclei of migrating DTCs are always positioned at the leading edge of the cells, even as these cells turn dorsally to contact the hypodermis and intestine. When the DTCs turn dorsally, VAB-10B1/spectraplakin acts in nuclear translocation by regulating the polarized growth of microtubules. The function of spectraplakin in nuclear positioning may be evolutionarily conserved. Here we discuss the possible reason for leading-edge positioning of the DTC nucleus.
