The process whose specific outcome is the progression of the eye over time, from its formation to the mature structure. The eye is the organ of sight.

The process whose specific outcome is the progression of the lens over time, from its formation to the mature structure. The lens is a transparent structure in the eye through which light is focused onto the retina. An example of this process is found in Mus musculus.

The process in which the anatomical structures of the lens are generated and organized. The lens is a transparent structure in the eye through which light is focused onto the retina. An example of this process is found in Mus musculus.

The process in which relatively unspecialized cells acquire specialized structural and/or functional features of a type B pancreatic cell. A type B pancreatic cell is a cell located towards center of the islets of Langerhans that secretes insulin.

The process in which relatively unspecialized cells acquire specialized structural and functional features of a pancreatic A cell. A pancreatic A cell is a cell in the pancreas that secretes glucagon.

The process in which relatively unspecialized cells acquire specialized structural and functional features that characterize a pancreatic delta cell. A delta cell is a cell of the pancreas that produces somatostatin.

Any process that activates or increases the rate or extent of cell proliferation.

The regionalization process in which specific areas of cell differentiation are determined along the anterior-posterior axis. The anterior-posterior axis is defined by a line that runs from the head or mouth of an organism to the tail or opposite end of the organism.

Any process that modulates the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA or circRNA (for protein-coding genes) and the translation of that mRNA or circRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.

The progression of the epithalamus over time from its initial formation until its mature state. The epithalamus is the small dorsomedial area of the thalamus including the habenular nuclei and associated fiber bundles, the pineal body, and the epithelial roof of the third ventricle.

The process whose specific outcome is the progression of the hindbrain over time, from its formation to the mature structure. The hindbrain is the posterior of the three primary divisions of the developing chordate brain, or the corresponding part of the adult brain (in vertebrates, includes the cerebellum, pons, and medulla oblongata and controls the autonomic functions and equilibrium).

The process in which a relatively unspecialized cell acquires the specialized features of a retinal cone cell.

Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter.

The process in which a relatively unspecialized cell acquires the specialized features of a retinal rod cell.

The progression of the cornea over time, from its formation to the mature structure. The cornea is the transparent structure that covers the anterior of the eye.

The process in which relatively unspecialized cells acquire specialized structural and functional features of a pancreatic epsilon cell. A pancreatic epsilon cell is a cell in the pancreas that secretes ghrelin.
