Tissue Renewal without Stem Cells01:23

Tissue Renewal without Stem Cells

2.2K
After cellular or tissue damage, the resident stem cells present in the human body can locally repair and regenerate the damaged tissue or organ. However, even though some tissues do not have stem cells, they can repair and regenerate with the help of pre-existing cells. For example, beta cells of the pancreas and hepatocytes of the liver can divide to renew and regenerate the tissue. Here, both cell division and cell death are well regulated by homeostasis.
However, failure of such a system...

Collagens are the Major Structural Proteins of ECM01:13

Collagens are the Major Structural Proteins of ECM

6.1K
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...

Type IV Collagen of Basal Lamina01:05

Type IV Collagen of Basal Lamina

3.2K
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.
A type IV collagen molecule has six alpha chains which can...

Stem Cell Therapy for Tissue Regeneration01:21

Stem Cell Therapy for Tissue Regeneration

4.8K
Stem cell therapy is a method used in regenerative medicine to repair and restore function to damaged tissues and organs. Stem cells have the potential to proliferate and differentiate into various tissue types, making them ideal candidates for tissue regeneration. For example, hematopoietic stem cell transplants are commonly used in blood cancer treatment to replenish damaged bone marrow and restore healthy blood cells.

Fibril-associated Collagen01:11

Fibril-associated Collagen

3.5K
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...

Overview of Regeneration and Repair01:19

Overview of Regeneration and Repair

5.6K
Regeneration and repair processes are critical in healing damages caused by injury, disease, and aging. In regeneration, the damaged tissue is entirely replaced with new growth that restores the original architecture and function. In contrast, tissue repair usually results in a fixed tissue architecture involving scar formation. Scars generally do not reestablish tissue function and may also exhibit structural abnormalities at the injury site.
Regeneration
All animals have varying degrees of...

Area of Science:

  • Biomaterials Science
  • Tissue Engineering
  • Regenerative Medicine

Background:

  • Collagen is the primary structural protein in native tissue extracellular matrix.
  • Its inherent biocompatibility makes it suitable for regenerative medicine applications.
  • Cellular interactions with collagen are mediated by integrins and influenced by fiber structure and chemistry.

Approach:

  • Collagen fibrillogenesis in vitro is controllable via factors like pH, ionic strength, and collagen structure.
  • Fiber stabilization is achieved through cross-linking post-formation.
  • Fabrication process control is key to optimizing collagen scaffold bioactivity.

Key Points:

  • Collagen's structural and chemical properties dictate cellular response.
  • Controlling fibrillogenesis allows for precise manipulation of collagen fiber formation.
  • Cross-linking stabilizes the formed collagen fibers, enhancing scaffold integrity.

Conclusions:

  • Tailoring collagen scaffold fabrication by controlling fibrillogenesis and cross-linking is crucial.
  • Optimized collagen scaffolds can be developed for specific tissue regeneration needs.
  • This approach improves the therapeutic efficacy of collagen-based regenerative medicine strategies.
