Summary
Collagen and calcium-binding EGF domain-1 (ccbe1) is essential for embryonic lymphatic vessel development. This gene is required for lymphangioblast budding and sprouting from veins during lymphangiogenesis.
Area of Science:
- Developmental Biology
- Vascular Biology
- Genetics
Background:
- Lymphatic vessels are crucial for fluid balance, nutrient absorption, immune responses, and cancer spread.
- Lymphangiogenesis, the formation of new lymphatic vessels, involves complex processes like budding and migration of specific cells called lymphangioblasts.
Purpose of the Study:
- To identify novel genes critical for embryonic lymphangiogenesis using a genetic screen.
- To elucidate the role of ccbe1 in the early development of lymphatic vessels.
Main Methods:
- A forward genetic screen was performed in zebrafish embryos.
- The function of the identified gene, ccbe1, was analyzed in relation to lymphangiogenesis.
Main Results:
- The gene ccbe1 (collagen and calcium-binding EGF domain-1) was identified as indispensable for embryonic lymphangiogenesis.
- ccbe1 functions at a similar developmental stage as Vegfc.
- ccbe1 is required for the budding of lymphangioblasts and the angiogenic sprouting of venous endothelium.
Conclusions:
- ccbe1 plays a vital role in the initiation of lymphatic vessel formation.
- Understanding ccbe1's function provides insights into the molecular mechanisms of lymphangiogenesis and potential therapeutic targets for diseases involving lymphatic vessels.

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...
01:07Development of Blood Vessels
The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...

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...
01:22Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal
Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.
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...

02:33Hedgehog Signaling Pathway
The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...
