The formation of ectoderm during gastrulation. Process by which a cell becomes capable of differentiating autonomously into an ectoderm cell in an environment that is neutral with respect to the developmental pathway; upon specification, the cell fate can be reversed. The commitment of cells to specific cell fates and their capacity to differentiate into particular kinds of cells. Positional information is established through protein signals that emanate from a localized source within a cell (the initial one-cell zygote) or within a developmental field. The process involved in the specification of cell identity. Once specification has taken place, a cell will be committed to differentiate down a specific pathway if left in its normal environment. The commitment of cells to specific cell fates of the endoderm, ectoderm and mesoderm as a part of gastrulation. A biological process whose specific outcome is the progression of a cell over time from an initial condition to a later condition. The process whereby relatively unspecialized cells acquire specialized structural and/or functional features of an ectodermal cell. Differentiation includes the processes involved in commitment of a cell to a specific fate. Any process that restricts, stops or prevents a cell from specifying into an ectoderm cell. Any process that mediates the specification of a cell into an ectoderm cell. The process by which a cell becomes committed to become part of the ectoderm.
