"A change in the morphology or behavior of a cell resulting from exposure to an activating factor such as a cellular or soluble ligand [goid 1775] [pmid 10508235] [evidence TAS]; 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 posttranslational phosphorylation of peptidyl-tyrosine to form peptidyl-O4'-phospho-L-tyrosine [goid 18108] [pmid 2536956] [evidence IDA]; A process that is carried out at the cellular level which results in the formation, arrangement of constituent parts, or disassembly of an extracellular matrix [goid 30198] [evidence IEA]; The process whose specific outcome is the progression of the lung over time, from its formation to the mature structure. In all air-breathing vertebrates the lungs are developed from the ventral wall of the oesophagus as a pouch which divides into two sacs. In amphibians and many reptiles the lungs retain very nearly this primitive sac-like character, but in the higher forms the connection with the oesophagus becomes elongated into the windpipe and the inner walls of the sacs become more and more divided, until, in the mammals, the air spaces become minutely divided into tubes ending in small air cells, in the walls of which the blood circulates in a fine network of capillaries. In mammals the lungs are more or less divided into lobes, and each lung occupies a separate cavity in the thorax [goid 30324] [evidence IEA]; Any process that activates or increases the frequency, rate or extent of cell migration [goid 30335] [pmid 17470632] [evidence IDA]; The process whose specific outcome is the progression of the male genitalia over time, from its formation to the mature structure [goid 30539] [evidence IEA]; The process whose specific outcome is the progression of a dentine-containing tooth over time, from its formation to the mature structure. A dentine-containing tooth is a hard, bony organ borne on the jaw or other bone of a vertebrate, and are composed mainly of dentine, a dense calcified substance, covered by a layer of enamel [goid 42475] [evidence IEA]; Any process that activates or increases the frequency, rate or extent of DNA replication [goid 45740] [pmid 10806482] [evidence IDA]; The phosphorylation by a protein of one or more of its own amino acid residues, or residues on an identical protein [goid 46777] [pmid 2536956] [evidence IDA]; The series of molecular signals generated as a consequence of a platelet-derived growth factor receptor binding to one of its physiological ligands [goid 48008] [pmid 2536956] [evidence IDA]; The series of molecular signals generated as a consequence of a platelet-derived growth factor receptor binding to one of its physiological ligands [goid 48008] [pmid 10806482] [evidence IDA]; Any process that activates or increases the frequency, rate or extent of multiplication or reproduction of fibroblast cells [goid 48146] [pmid 10806482] [evidence IDA]"
