Intercellular signaling peptides and proteins that regulate the proliferation of new blood vessels under normal physiological conditions (ANGIOGENESIS, PHYSIOLOGICAL). Aberrant expression of angiogenic proteins during disease states such as tumorigenesis can also result in PATHOLOGICAL ANGIOGENESIS.

Synonyms: Angiogenic Proteins, Angiogenic Protein, 0, Protein, Angiogenic, Angiogenic Peptides, Angiogenic Peptide, Peptide, Angiogenic
