The process whose specific outcome is the progression of nervous tissue over time, from its formation to its mature state.

Any process that activates or increases the frequency, rate or extent of the introduction of a phosphate group to a tyrosine residue of a STAT (Signal Transducer and Activator of Transcription) protein.

The process whose specific outcome is the progression of a neuron over time, from initial commitment of the cell to a specific fate, to the fully functional differentiated cell.

Any series of molecular signals initiated by the binding of leukemia inhibitory factor to a receptor on the surface of the target cell, and ending with regulation of a downstream cellular process, e.g. transcription.

Any process that mediates the transfer of information from one cell to another. This process includes signal transduction in the receiving cell and, where applicable, release of a ligand and any processes that actively facilitate its transport and presentation to the receiving cell. Examples include signaling via soluble ligands, via cell adhesion molecules and via gap junctions.

The process whose specific outcome is the progression of nervous tissue over time, from its formation to its mature state.

The process whose specific outcome is the progression of the muscle over time, from its formation to the mature structure. The muscle is an organ consisting of a tissue made up of various elongated cells that are specialized to contract and thus to produce movement and mechanical work.

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

A series of molecular signals initiated by the binding of a cytokine to a receptor on the surface of a cell, and ending with regulation of a downstream cellular process, e.g. transcription.

The process in which a relatively unspecialized cell acquires specialized features of a neuron.

Any process that activates or increases the frequency, rate or extent of the introduction of a phosphate group to a tyrosine residue of a STAT (Signal Transducer and Activator of Transcription) protein.

Any series of molecular signals initiated by the binding of leukemia inhibitory factor to a receptor on the surface of the target cell, and ending with regulation of a downstream cellular process, e.g. transcription.

The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
