Summary
A new computational model predicts how cells and collagen interact under mechanical strain. This model helps understand tissue remodeling in engineered arteries and heart valves.
Area of Science:
- Biomaterials Science
- Computational Biology
- Tissue Engineering
Background:
- Cells typically reorient with cyclic strain.
- Extracellular collagen in 3D tissues complicates this cellular response.
Purpose of the Study:
- To develop a computational model predicting cell and collagen behavior under mechanical stimuli.
- To investigate collagen's influence on cell reorientation via contact guidance or steric hindrance.
Main Methods:
- Extended a computational model to include collagen's effects (contact guidance, steric hindrance).
- Developed a cell-induced collagen realignment law.
- Simulated cell-populated collagen gels under various strain conditions and collagen densities.
Main Results:
- Model simulations align with existing experimental findings.
- The model successfully predicts cellular and collagenous tissue remodeling.
Conclusions:
- The computational approach offers a valuable tool for studying collagenous tissue remodeling.
- This model can aid in understanding and designing tissue-engineered cardiovascular components.

01:11Fibril-associated Collagen
3.4K
Fibril-associated collagens are a type of collagens present in the extracellular matrix with interrupted triple helices or FACIT (Fibril-associated collagens interrupted triple-helices). FACIT help connect and attach the collagen fibrils with each other as well as with other proteins of the extracellular matrix.
For example, the type II collagen fibrils in cartilage have covalently bound type IX fibril-associated collagens at regular intervals. Other types of fibril-associated collagens are...

01:13Collagens are the Major Structural Proteins of ECM
5.8K
Three main types of fibers are secreted by fibroblasts: collagen fibers, elastic fibers, and reticular fibers. Collagen fiber is made from fibrous protein subunits linked together to form a long, straight fiber. Collagen fibers, while flexible, have great tensile strength, resist stretching, and give ligaments and tendons their characteristic resilience and strength. These fibers hold connective tissues together, even during the body's movement.

01:05Type IV Collagen of Basal Lamina
3.1K
Type IV collagen is a 400 nm long, network-forming collagen that acts as a barrier between the epithelial and endothelial cells. Type IV collagen forms the backbone of the basement membrane by scaffolding with laminin, entactin, proteoglycans, and fibronectin. Apart from rendering structural support to the basement membrane, it also helps entail signaling potentials necessary for both pathological and physiological functions.

01:27Combined Effects of Drugs: Synergism
7.0K
Synergism is a useful mechanism where combining two or more drugs is more effective than each constituent used alone. Such combinations are also called supra-additive interactions. The drugs collectively enhance the final therapeutic effect by acting on different targets. Another advantage is that the low dose of each constituent drug is sufficient to achieve the desired effect. This helps reduce the duration of therapy and lower the adverse effects of these drugs.

01:30Combined Effects of Drugs: Antagonism
11.8K
The combined effects of drugs can result in various interactions, of which an important type is antagonism. Antagonism is a mechanism where one drug inhibits or counteracts the effects of another drug. Antagonism can occur through various means, including receptor binding, allosteric modulation, functional interaction, chemical reactions, and pharmacokinetic processes.
The most common type is receptor antagonism, where one drug acts as an antagonist to block the effects of another drug by...

01:13Location and Orientation of the Heart
10.7K
The human heart, despite its modest size and weight, is an organ of remarkable strength and endurance. Roughly the size of a fist, the heart weighs between 250 and 350 grams and is nestled within the mediastinum, the medial cavity of the thorax. It extends obliquely for about 12 to 14 cm, resting on the superior surface of the diaphragm. The heart is positioned anterior to the vertebral column and posterior to the sternum, with two-thirds of its mass lying to the left of the midsternal line.
