- Discuss their potential in regenerative medicine and beyond.
Main Methods:
- Review of existing literature on DNA-collagen complex formation and applications.
- Analysis of structural properties across different length scales (nanoparticles, microfibers, hydrogels).
- Examination of various nucleic acid types (siRNA, aptamers) and collagen interactions.
Main Results:
- DNA-collagen complexes exhibit biocompatibility, bioactivity, and tunability.
- Complex formation is controllable by component ratios and types.
- Self-assembly of functional nucleic acids like aptamers occurs rapidly at room temperature.

01:11Fibril-associated Collagen
2.5K
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 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...

01:13Collagens are the Major Structural Proteins of ECM
4.0K
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.
