"The process whose specific outcome is the progression of the skeleton over time, from its formation to the mature structure. The skeleton is the bony framework of the body in vertebrates (endoskeleton) or the hard outer envelope of insects (exoskeleton or dermoskeleton) [goid 1501] [pmid 10391213] [evidence TAS]; The process whose specific outcome is the progression of the ureteric bud over time, from its formation to the mature structure [goid 1657] [evidence IEA]; The process whose specific outcome is the progression of nervous tissue over time, from its formation to its mature state [goid 7399] [pmid 10075854] [evidence TAS]; The process whose specific outcome is the progression of the mesoderm over time, from its formation to the mature structure. The mesoderm is the middle germ layer that develops into muscle, bone, cartilage, blood and connective tissue [goid 7498] [pmid 10075854] [evidence TAS]; Any process that stops, prevents or reduces the rate or extent of cell proliferation [goid 8285] [evidence IEA]; Morphogenesis of an organ. An organ is defined as a tissue or set of tissues that work together to perform a specific function or functions. Morphogenesis is the process by which anatomical structures are generated and organized. Organs are commonly observed as visibly distinct structures, but may also exist as loosely associated clusters of cells that work together to perform a specific function or functions [goid 9887] [evidence IEA]; The process whose specific outcome is the progression of the pancreas over time, from its formation to the mature structure. The pancreas is an endoderm derived structure that produces precursors of digestive enzymes and blood glucose regulating enzymes [goid 31016] [evidence IEA]; The increase in size or mass of an entire organism, a part of an organism or a cell [goid 40007] [evidence IEA]; Any process that stops, prevents or reduces the frequency, rate or extent of cell differentiation [goid 45596] [evidence IEA]; A developmental process, independent of morphogenetic (shape) change, that is required for a cell to attain its fully functional state [goid 48469] [evidence IEA]; The process by which the anatomical structures of the eye are generated and organized. Morphogenesis pertains to the creation of form. The camera-type eye is an organ of sight that receives light through an aperture and focuses it through a lens, projecting it on a photoreceptor field [goid 48593] [evidence IEA]"
