The process whereby a relatively unspecialized cell acquires specialized features of a hair cell. 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. 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. Signaling at long or short range between cells that results in the commitment of a cell to a certain fate. The process by which the anatomical structures of the leaf are generated and organized. Morphogenesis pertains to the creation of form. Any process that mediates the transfer of information from one cell to another. 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. The regionalization process of establishing the non-random spatial arrangement of trichomes on the surface and margin of a leaf. Process involves signaling between adjacent epidermal cells that results in differentiation of some epidermal cells into trichomes. The process whereby a relatively unspecialized epidermal cell acquires the specialized features of a trichome cell. An example of this process is found in Arabidopsis thaliana.
