Gap Junctions01:37

Gap Junctions

48.1K
Multicellular organisms employ a variety of ways for cells to communicate with each other. Gap junctions are specialized proteins that form pores between neighboring cells in animals, connecting the cytoplasm between the two, and allowing for the exchange of molecules and ions. They are found in a wide range of invertebrate and vertebrate species, mediate numerous functions including cell differentiation and development, and are associated with numerous human diseases, including cardiac and...

Gap Junctions

9.2K
The cytoplasm of adjacent animal cells can exchange small molecules, ions, and secondary messengers via the communication channels which form the gap junctions. These junctions comprise a few hundred to thousands of molecular channels, each made of two halves, called the connexon hemichannel. A connexon is a hexamer of six transmembrane connexin proteins, which assemble radially, thus forming a pore or channel in the center. One connexon hemichannel docks with a corresponding connexon on the...

Development of Blood Vessels

2.0K
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...

Anatomy of Blood Vessels

4.3K
The vascular system, an integral part of the circulatory system, comprises various blood vessels that play crucial roles in maintaining the body's homeostasis. These blood vessels form a complex and efficient circulatory network. The three primary categories of blood vessels are the arteries, veins, and capillaries.
Arteries
Arteries circulate oxygenated blood from the heart, except the pulmonary artery, which transports deoxygenated blood to the lungs. Large arteries, such as the aorta,...

Overview of Cell-Matrix Interactions01:24

Overview of Cell-Matrix Interactions

8.0K
The extracellular matrix or ECM holds cells together to form a tissue and allows the cells within the tissue to communicate. ECM comprises proteins such as fibronectin, collagen, laminin, etc. The most abundant protein in this space is collagen. Collagen fibers are interwoven with carbohydrate-containing protein molecules called proteoglycans. ECM allows cell migration and provides a structural scaffold at cell adhesion that anchors the cell when the extracellular matrix proteins interact with...

Area of Science:

  • Medical Imaging
  • Computational Anatomy
  • Biomedical Engineering

Background:

  • 3D surface reconstruction of liver vessels is challenging due to low contrast in medical images and complex multi-furcation structures.
  • Existing shape-based methods struggle with the intricate geometry of liver vasculature.

Purpose of the Study:

  • To develop an effective and robust technique for reconstructing liver vessel surfaces, particularly addressing multi-furcation complexities.
  • To improve the accuracy and editability of 3D liver vessel models.

Main Methods:

  • The Gap Border Pairing (GBPa) method utilizes a preprocessed tree-like skeleton of segmented liver vessels.
  • Optimized elliptic cross-section rings are generated and fitted to branching lines.
  • Tubular surface meshes are created, and transitional regular meshes reconstruct multi-furcation parts.
  • The final model is refined using subdivision and facet grouping for topology maintenance and editability.

Main Results:

  • The GBPa method successfully reconstructs surfaces of liver vessels with complicated multi-furcations.
  • The generated models demonstrate high-level editability.
  • Experimental results confirm the accuracy of the GBPa model, showing minimal boundary deviations from segmented volumes.

Conclusions:

  • Gap Border Pairing (GBPa) offers an accurate and robust solution for 3D liver vessel surface reconstruction, especially for complex anatomical regions.
  • The method's parallel implementation capability enhances efficiency when segmented volumes and skeletons are available.
  • GBPa provides a valuable tool for medical imaging analysis and surgical planning.
