The process that results in the patterns of cell differentiation that will arise in an embryo. Any developmental process that results in the creation of defined areas or spaces within an organism to which cells respond and eventually are instructed to differentiate. Allocation of cells to parasegments in the embryo, through the action of overlapping series of pair rule gene activities. The regionalization process that divides an organism or part of an organism into a series of semi-repetitive parts, or segments, often arranged along a longitudinal axis. Division of the 14 parasegments of the embryo into anterior and posterior compartments; exemplified by the actions of the segment polarity gene products. The regionalization process that divides the spatial regions of an embryo into serially repeated regions. The hierarchical steps resulting in the progressive subdivision of the anterior/posterior axis of the embryo. The pattern specification process by which an axis or axes is subdivided in space to define an area or volume in which specific patterns of cell differentiation will take place or in which cells interpret a specific environment.
