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

Any process that activates or increases the frequency, rate or extent of addition of phosphate groups to amino acids within a protein.

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

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 or rate of myeloid dendritic cell activation.

Any process that activates or increases the frequency, rate or extent of natural killer cell proliferation.

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

The stages of blood cell formation that take place within the embryo.

Any process that activates or increases the frequency, rate or extent of myoblast differentiation. A myoblast is a mononucleate cell type that, by fusion with other myoblasts, gives rise to the myotubes that eventually develop into skeletal muscle fibers.

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

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

Any biological process involved in the maintenance of the steady-state number of cells within a population of cells in a tissue.

Any biological process involved in the maintenance of the steady-state number of cells within a population of cells in a tissue.

A process that activates or increases the frequency, rate or extent of cell proliferation in the bone marrow.

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

Any process that increases the rate, frequency, or extent of the multiplication or reproduction of osteoclasts, resulting in the expansion of an osteoclast cell population.

Any process that increases the rate, frequency, or extent of the multiplication or reproduction of osteoclasts, resulting in the expansion of an osteoclast cell population.

Any process that activates or increases the frequency, rate or extent of myoblast fusion.

An intracellular protein kinase cascade containing at least a MAPK, a MAPKK and a MAP3K. The cascade can also contain an additional tiers: the upstream MAP4K. The kinases in each tier phosphorylate and activate the kinase in the downstream tier to transmit a signal within a cell.

The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell.

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 stages of blood cell formation that take place within the embryo.

That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.

The external part of the cell wall and/or plasma membrane.

The component of a plasma membrane consisting of gene products and protein complexes that penetrate the external side of the plasma membrane only, either directly or via some covalently attached hydrophobic anchor.

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.

A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.

The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
