Fibril-associated Collagen01:11

Fibril-associated Collagen

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...
Structural Protein Function01:56

Structural Protein Function

Structural proteins are a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures such as bones, cartilage, hair, and muscles. This group includes proteins such as collagen, actin, myosin, and keratin.
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity.  In bones and teeth, it mineralizes to form...
Collagens are the Major Structural Proteins of ECM01:13

Collagens are the Major Structural Proteins of ECM

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.
Connective tissue proper includes loose...
What are Membranes?01:54

What are Membranes?

A key characteristic of life is the ability to separate the external environment from the internal space. To do this, cells have evolved semi-permeable membranes that regulate the passage of biological molecules. Additionally, the cell membrane defines a cell’s shape and interactions with the external environment. Eukaryotic cell membranes also serve to compartmentalize the internal space into organelles, including the endomembrane structures of the nucleus, endoplasmic reticulum and Golgi...

Area of Science:

  • Biomaterials Science
  • Tissue Engineering
  • Biomedical Engineering

Background:

  • Collagen membranes are crucial in regenerative medicine.
  • Developing ordered collagen structures is key for enhanced therapeutic delivery.
  • Current methods may lack sufficient microscopic control.

Purpose of the Study:

  • To create and characterize highly ordered collagen membranes.
  • To evaluate the structural integrity and permeability of these membranes.
  • To explore their potential in surface injury treatment.

Main Methods:

  • Acid-soluble collagen was used to fabricate membranes.
  • Two distinct methods were employed to achieve structural orientation.
  • Characterization involved UV/IR spectroscopy, electron microscopy, optical microscopy, and laser diffractometry.

Main Results:

  • Both fabrication techniques yielded membranes with a high degree of microscopic order.
  • Structural analysis confirmed consistent organization across the membranes.
  • Permeability studies demonstrated controlled passage of rifamycin, ascorbic acid, and NaCl.

Conclusions:

  • The developed collagen membranes exhibit significant microscopic order.
  • Their controlled permeability and structural properties indicate suitability for wound healing.
  • These membranes represent a promising biomaterial for surface injury applications.
