The process in which a relatively unspecialized cell acquires the specialized features of a natural killer cell.

Any process in which STAT proteins (Signal Transducers and Activators of Transcription) and JAK (Janus Activated Kinase) proteins convey a signal to trigger a change in the activity or state of a cell. The receptor signaling pathway via JAK-STAT begins with activation of a receptor and proceeeds through STAT protein activation by members of the JAK family of tyrosine kinases. STAT proteins dimerize and subsequently translocate to the nucleus. The pathway ends with regulation of target gene expression by STAT proteins.

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

Any process that modulates the frequency, rate or extent of the chemical reactions and pathways involving steroids.

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 accumulation and maintenance in cells or tissues of lipids, compounds soluble in organic solvents but insoluble or sparingly soluble in aqueous solvents. Lipid reserves can be accumulated during early developmental stages for mobilization and utilization at later stages of development.

The process in which a relatively unspecialized precursor cell acquires specialized features of a lymphocyte. A lymphocyte is a leukocyte commonly found in the blood and lymph that has the characteristics of a large nucleus, a neutral staining cytoplasm, and prominent heterochromatin.

Any process that modulates the frequency, rate or extent of attachment of a cell to another cell or to the extracellular matrix.

The process in which a myeloid precursor cell acquires specializes features of an erythrocyte.

The process in which a myeloid precursor cell acquires specializes features of an erythrocyte.

Any process that modulates the frequency, rate or extent of epithelial cell differentiation.

Any process that activates or increases the frequency, rate or extent of growth of an organism to reach its usual body size.

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

The chemical reactions and pathways involving progesterone, a steroid hormone produced in the ovary which prepares and maintains the uterus for pregnancy. Also found in plants.

The process of regulating the proliferation and elimination of T cells such that the total number of T cells within a whole or part of an organism is stable over time in the absence of an outside stimulus.

Any process that stops, prevents, or reduces the frequency, rate or extent of cell death by apoptotic process.

Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of interleukin-2.

Any process that activates or increases the frequency, rate or extent of B cell differentiation.

Any process that activates or increases the frequency, rate or extent of myeloid cell differentiation.

Any process that stops, prevents, or reduces the frequency, rate or extent of erythrocyte differentiation.

Any process that activates or increases the rate or extent of progression through the mitotic cell cycle.

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

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

The process whose specific outcome is the progression of the secondary female sexual characteristics over time, from their formation to the mature structures. In female humans, these include growth of axillary and pubic hair, breast development and menstrual periods. Their development occurs in response to sex hormone secretion.

The process whose specific outcome is the progression of the secondary male sexual characteristics over time, from their formation to the mature structures. In male humans, these include growth of axillary, chest, and pubic hair, voice changes, and testicular/penile enlargement. Development occurs in response to sex hormone secretion.

The increase in size or mass of an entire organism, a part of an organism or a cell, where the increase in size or mass has the specific outcome of the progression of the organism over time from one condition to another.

The process whose specific outcome is the progression of an erythrocyte over time, from its formation to the mature structure.

Any process that activates or increases the frequency, rate or extent of the inflammatory response.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

That part of the nuclear content other than the chromosomes or the nucleolus.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
