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

Any process that increases the rate of phospholipase C activity.

Any process that activates, maintains or increases the frequency, rate or extent of smooth muscle cell migration.

The controlled self-propelled movement of a cell from one site to a destination guided by molecular cues. Cell migration is a central process in the development and maintenance of multicellular organisms.

The phosphorylation of peptidyl-tyrosine to form peptidyl-O4'-phospho-L-tyrosine.

Any process that activates or increases the activity of a phosphoprotein phosphatase.

The orderly movement of a cell from one site to another that will contribute to the differentiation of an endothelial cell that will form de novo blood vessels and tubes.

Any process that activates or increases the frequency, rate or extent of phosphatidylinositol 3-kinase activity.

The chemical reactions and pathways involving phosphatidylinositol, any glycophospholipid in which a sn-glycerol 3-phosphate residue is esterified to the 1-hydroxyl group of 1D-myo-inositol.

The phosphorylation by a protein of one or more of its own amino acid residues (cis-autophosphorylation), or residues on an identical protein (trans-autophosphorylation).

The series of molecular signals generated as a consequence of a platelet-derived growth factor receptor binding to one of its physiological ligands.

A series of molecular signals in which a cell uses a phosphatidylinositol-mediated signaling to convert a signal into a response. Phosphatidylinositols include phosphatidylinositol (PtdIns) and its phosphorylated derivatives.

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

The orderly movement of a cell from one site to another that will contribute to the formation of new blood vessels in the heart from pre-existing blood vessels.

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

Any process that activates or increases the frequency, rate or extent of signal transduction mediated by the ERK1 and ERK2 cascade.

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.

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

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

The region of the plasma membrane located at the apical end of the cell.

The component of the plasma membrane consisting of the gene products and protein complexes having either part of their peptide sequence embedded in the hydrophobic region of the membrane or some other covalently attached group such as a GPI anchor that is similarly embedded in the membrane.
