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 whose specific outcome is the progression of the epidermis over time, from its formation to the mature structure. The epidermis is the outer epithelial layer of a plant or animal, it may be a single layer that produces an extracellular material (e.g. the cuticle of arthropods) or a complex stratified squamous epithelium, as in the case of many vertebrate species. 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 process by which a cell becomes capable of differentiating autonomously into an epidermal cell in an environment that is neutral with respect to the developmental pathway; upon specification, the cell fate can be reversed. The process involved in the specification of an atrichoblast. The process by which a cell becomes capable of differentiating autonomously into an limb basal epidermal cell in an environment that is neutral with respect to the developmental pathway; upon specification, the cell fate can be reversed. A biological process whose specific outcome is the progression of a cell over time from an initial condition to a later condition. The process by which a cell becomes capable of differentiating autonomously into an limb granular cell in an environment that is neutral with respect to the developmental pathway; upon specification, the cell fate can be reversed. The process by which a cell becomes capable of differentiating autonomously into a limb spinous cell in an environment that is neutral with respect to the developmental pathway; upon specification, the cell fate can be reversed. The process whereby relatively unspecialized cells, e.g. embryonic or regenerative cells, acquire specialized structural and/or functional features that characterize the cells, tissues, or organs of the mature organism or some other relatively stable phase of the organism's life history. Differentiation includes the processes involved in commitment of a cell to a specific fate and its subsequent development to the mature state. The process whereby a relatively unspecialized cell acquires specialized features of an epidermal cell, any of the cells making up the epidermis.
