Blood vessel formation when new vessels emerge from the proliferation of pre-existing blood vessels.

The process in which the anatomical structures of branches in a tube are generated and organized. A tube is a long hollow cylinder.

Any process involved in the maintenance of an internal steady state of calcium ions within an organism or cell.

A series of molecular signals in which a cell uses calcium ions released from an intracellular store to convert a signal into a response.

The commitment of cells to specific cell fates and their capacity to differentiate into particular kinds of cells. Positional information is established through protein signals that emanate from a localized source within a cell (the initial one-cell zygote) or within a developmental field.

A developmental process, independent of morphogenetic (shape) change, that is required for a cell to attain its fully functional state.

The orderly movement of endothelial cells into the extracellular matrix in order to form new blood vessels involved in sprouting angiogenesis.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a vascular endothelial growth factor stimulus.

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

The process in which a mesodermal, bone marrow or neural crest cell acquires specialized features of an endothelial cell, a thin flattened cell. A layer of such cells lines the inside surfaces of body cavities, blood vessels, and lymph vessels, making up the endothelium.

The process whose specific outcome is the progression of an endothelium over time, from its formation to the mature structure. Endothelium refers to the layer of cells lining blood vessels, lymphatics, the heart, and serous cavities,and is derived from bone marrow or mesoderm. Corneal endothelium is a special case, derived from neural crest cells.

The process whose specific outcome is the progression of the alveolus over time, from its formation to the mature structure. The alveolus is a sac for holding air in the lungs; formed by the terminal dilation of air passageways.

The process whose specific outcome is the progression of a lymph vessel over time, from its formation to the mature structure.

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

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

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

The phosphorylation by a protein of one or more of its own tyrosine amino acid residues, or a tyrosine residue on an identical protein.

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

Any process that activates or increases angiogenesis.

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

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

Any process that increases the rate, frequency, or extent of the orderly movement of an endothelial cell into the extracellular matrix to form an endothelium.

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

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

Any process that activates or increases the frequency, rate or extent of focal adhesion assembly, the establishment and maturation of focal adhesions.

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

The process of activating or increasing the rate or extent of mesenchymal cell proliferation. Mesenchymal cells are loosely organized embryonic cells.

Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of a nitric oxide synthase enzyme.

Any process that activates or increases the frequency, rate or extent of signal transduction mediated by the phosphatidylinositol 3-kinase cascade.

Any process that activates or increases the frequency, rate or extent of the directed movement of a motile cell or organism towards a higher concentration in a concentration gradient of a specific chemical.

The phosphorylation by a protein of one or more of its own amino acid residues, or residues on an identical protein.

Any process that modulates the surface configuration of a cell.

A process in which the transfer of one or more phosphate groups to a substrate transmits a signal to the phosphorylated substrate.

Any process involved in the maintenance of a steady-state level of the surface-active lipoprotein mixture which coats the alveoli.

A series of molecular signals initiated by the binding of an extracellular ligand to a receptor on the surface of the target cell where the receptor possesses tyrosine kinase activity, and ending with regulation of a downstream cellular process, e.g. transcription.

Any series of molecular signals initiated by the binding of an extracellular ligand to a vascular endothelial growth factor receptor (VEGFR) located on the surface of the receiving cell, and ending with regulation of a downstream cellular process, e.g. transcription.

A series of molecular signals initiated by the binding of a vascular endothelial growth factor (VEGF) to a receptor on the surface of the target cell, and ending with regulation of a downstream cellular process, e.g. transcription.

The differentiation of endothelial cells from progenitor cells during blood vessel development, and the de novo formation of blood vessels and tubes.

Interactions, directly with the host cell macromolecular machinery, to allow virus replication.
