Gastrulation is a fundamental process that reorganizes the primary germ layers to shape the internal and external features of an early embryo. Morphogenetic movements underlying this process can be classified into a variety of different types of cellular movements. I will focus on investigating in this thesis two types of cell movements in the dorsal mesoderm; mediolateral cell intercalation and convergence and extension. During gastrulation, mesoderm cells send protrusions to gain traction on neighboring cells and the surrounding extracellular matrix; a process called mediolateral cell intercalation. Mesoderm cells use this type of cell movement to converge and extend the dorsal …
