Summary
Lymphatic endothelial cell (LEC) proliferation in lymph nodes drives disease. Targeting lymphangiogenesis, mediated by VEGF factors, is crucial for treating cancer metastasis and inflammation.
Area of Science:
- Biomedical research
- Vascular biology
- Pathogenesis of human diseases
Background:
- Lymphatic endothelial cell (LEC) proliferation occurs in tumor and inflamed tissues, and regional lymph nodes.
- Lymph node lymphangiogenesis (LNLG) is increasingly recognized for its role in human disease pathogenesis.
- LEC functions and lymphatic remodeling influence tumor metastasis and inflammation.
Purpose of the Study:
- To explore the role of lymph node lymphangiogenesis (LNLG) in disease.
- To understand the mechanisms of LEC proliferation and lymphatic remodeling.
- To identify key mediators in inflammation- or tumor-induced LNLG.
Main Methods:
- Literature review on lymphangiogenesis and its mediators.
- Analysis of the roles of VEGF-A/VEGFR-2 and VEGF-C/-D/VEGFR-3 in LNLG.
- Examination of LEC functional features and lymphatic remodeling.
Main Results:
- VEGF-A/VEGFR-2 and VEGF-C/-D/VEGFR-3 are key mediators of inflammation- or tumor-induced LNLG.
- LEC proliferation and lymphatic remodeling are critical in tumor metastasis and inflammation.
- LNLG is implicated in the pathogenesis of various human diseases.
Conclusions:
- Understanding LNLG mechanisms can inform therapeutic strategies for cancer and inflammatory diseases.
- Targeting lymphangiogenesis, particularly in lymph nodes, holds therapeutic potential.
- The link between inflammation and lymphangiogenesis is vital for cancer metastasis research.

02:17The Tumor Microenvironment
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
01:10Mechanism of Angiogenesis
Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...
02:30Metastasis
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

01:15Development of the Lymphatic System
The development of lymphatic tissues and vessels in embryonic life begins around the fifth week. These structures originate from the mesoderm layer, with lymph sacs emerging from developing veins.
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...

01:16Lymphatic Vessels and Lymph Transport
Lymphatic vessels, known as lymphatics, are crucial in transporting lymph from peripheral tissues to our venous system. This process begins with lymph entering through tiny capillaries that branch through tissues. These capillaries have unique features such as larger diameters, thinner walls, and a distinctive one-way valve system formed by overlapping endothelial cells.
This one-way system allows fluids, solutes, and even pathogens to enter but prevents their return to the intercellular spaces.

01:24Regulation of Angiogenesis and Blood Supply
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...
