Description
Cell migration involved in sprouting angiogenesis (GO:0002042) is the biological process in which endothelial cells move in an orderly fashion into the extracellular matrix to form new blood vessels during sprouting angiogenesis. This process is fundamental to vascular development and to adult revascularization after ischemic injury, including acute myocardial infarction. Researchers study it because endothelial cell motility is a rate-limiting step in sprout extension, and its dysregulation underlies major human diseases such as diabetic retinopathy, atherosclerosis, and cancer [2,6,8]. The QuickGO definition emphasizes the orderly movement of endothelial cells into the extracellular matrix specifically in the context of sprouting angiogenesis. Mechanistically, this migration is coupled to VEGF-Ang-Tie2 signaling, FGF-dependent metabolic control, and Rho GTPase-mediated cytoskeletal remodeling [4,5,7]. Understanding GO:0002042 therefore requires integrating growth factor signaling, metabolic regulation, and cell-matrix interactions [1,4,5].

What Is GO:0002042?
In simple terms, GO:0002042 is the process by which endothelial cells crawl into surrounding tissue to build new blood vessel sprouts. According to the QuickGO definition, it is the orderly movement of endothelial cells into the extracellular matrix in order to form new blood vessels involved in sprouting angiogenesis. This term captures the directed motility phase of sprouting, distinct from endothelial proliferation or tube formation, and is driven by growth factor gradients and matrix remodeling [1,4,7].
Why Is cell migration involved in sprouting angiogenesis Important in Cell Biology?
GO:0002042 is important because endothelial cell migration is the engine of sprout elongation, and its precise regulation determines whether tissues are properly revascularized or pathologically vascularized. After acute myocardial infarction, therapeutic angiogenesis depends on efficient endothelial migration into the infarcted matrix. In diabetic retinopathy and atherosclerosis, aberrant endothelial motility contributes to microvascular anomalies and plaque instability [2,6]. In triple-negative breast cancer, BRCA1 mutation promotes sprouting angiogenesis through inflammatory cancer-associated fibroblasts, linking this process to tumor progression. Thus, GO:0002042 sits at the intersection of regenerative medicine and major disease mechanisms [1,6,8].

What Happens During cell migration involved in sprouting angiogenesis?
Initiation by VEGF-Ang-Tie2 signaling
In simple terms: Growth factors tell endothelial cells to start moving.
Sprouting angiogenesis begins when VEGF and Ang-Tie2 signaling activate endothelial cells, promoting their migration into the extracellular matrix [1,4]. In three-dimensional co-culture models, TGF-beta1-treated DPSCs regulate angiogenic sprouting of HUVECs through VEGF-Ang-Tie2 signaling. This signaling axis establishes the directional cue for endothelial cell movement.
Metabolic control by FGF signaling
In simple terms: FGF signaling provides the energy and building blocks for moving cells.
FGF-dependent metabolic control of vascular development is required for endothelial cell migration during sprouting. This pathway links growth factor signaling to metabolic reprogramming, enabling endothelial cells to sustain the energetic demands of migration.
Cytoskeletal remodeling via RhoGEF Trio
In simple terms: RhoGEF Trio helps reorganize the cell skeleton so cells can crawl.
Endothelial RhoGEF Trio is involved in angiogenesis and regulates cytoskeletal dynamics necessary for endothelial cell migration. Trio-mediated Rho GTPase activation promotes the actin remodeling that drives sprout extension.
Matrix invasion and sprout elongation
In simple terms: Cells push through the matrix to extend new vessel sprouts.
Endothelial cells move into the extracellular matrix in an orderly manner to form new blood vessels. This step requires coordinated cell-matrix interactions and is influenced by RNA m6A modification in atherosclerosis. YBX1-driven TUBB6 upregulation facilitates ocular angiogenesis via the WNT3A-FZD8 pathway, supporting matrix invasion.
Pathological amplification in disease
In simple terms: In disease, this migration can become excessive or abnormal.
MAP4K4 aggravates microvascular anomalies in diabetic retinopathy in a YTHDF2-dependent manner, linking this process to pathological angiogenesis. BRCA1 mutation promotes sprouting angiogenesis in inflammatory cancer-associated fibroblasts of triple-negative breast cancer.
