Specific genes called heterochronic genes control the timing and sequence of developmental events during larval stages of C. elegans. Mutations in heterochronic genes can cause skipping or reiteration of cell fates associated with certain larval stages. lin-14 and lin-28 are two well-studied heterochronic genes. LIN-14 acts during the first larval stage (L1) and controls events of the L1 and L2 stages, LIN-28 acts during the L2 stage and controls its events.

Cells can migrate collectively in tightly or loosely-associated groups during tissue and organ formation, during embryonic development, in tumor metastases, and in wound healing. Drosophilaborder cellsserve as an excellent genetic model of collective cell migration inside a developing tissue. During ovarian development, 6-8 cells form the border cell cluster and migrate together as a cohesive group to reach the large oocyte. Previous experiments have shown that Nuclear inhibitor of Protein Serine Threonine Phosphatase 1 (NiPP1) causes border cells to separate into single cells, rather than stay in a group, and limits their ability to migrate. NiPP1 inhibits the …
