It can refer to morphogenetic processes in which the embryo takes form and it is this process that is the initial step towards gastrulation. The process also covers the massive reorganization of the embryo right from a spherical ball of cell into a multi-layered organism which has differentiated germ layers.
You can also use the word invagination for the formation of cleavage furrow that happened during cytokinesis in animal cells. In some bacteria invagination is a region of cell membrane which is very tightly-folded.
