Liver diseases are induced by many causes that promote fibrosis or cirrhosis. Transplantation is the only option for recovering health. However, given the scarcity of transplantable organs, alternatives must be explored. Our research proposes the implantation of collagen scaffolds in liver tissue from an animal model.

Collagen is another widely used biomaterial that has found popularity in commercial applications, such as photography. Collagen has more recently been used in tissue engineering applications, by creating hydrogels that provide structure to engineered tissue. This video introduces collagen as a biomaterial, demonstrates how it is harvested from porcine skin, and shows how the material is used to create a hydrogel for tissue engineering applications. Finally, several applications of the material...

In newt, the lens regenerates always from the dorsal iris by transdifferentiation of the iris pigmented epithelial cells (IPEs). Here we describe a procedure to culture dorsal and ventral newt IPE cells and their implantation to the newt eye. The implanted cells are then studied by tissue sectioning and immunohistochemistry.

Tissue Regeneration with Somatic Stem Cells

2023
Somatic or adult stem cells, like embryonic stem cells, are capable of self-renewal but demonstrate a restricted differentiation potential. Nonetheless, these cells are crucial to homeostatic processes and play an important role in tissue repair. By studying and manipulating this cell population, scientist may be able to develop new regenerative therapies for injuries and diseases. This video first defines somatic stem cells, and then explores the role these cells play in tissue regeneration.
FAQs
Fibroblasts and related cells begin the process by synthesizing procollagen, an initial collagen precursor. That procollagen then undergoes processing before being assembled into extracellular matrix fibers. This sequence connects cellular production with the development of organized tissue structure, making fibroblast activity an important consideration when studying repair, wound healing, or regenerative treatments.
Effective repair requires more than producing new collagen. Older or damaged collagen must also be degraded and replaced so the extracellular matrix can be renewed rather than simply accumulated. The balance between synthesis, processing, assembly, and removal helps determine whether repaired tissue regains appropriate organization and supports restoration of structure and function.
Processing procollagen is followed by its assembly into extracellular matrix fibers, where collagen contributes to the organization and strength of connective tissues. This step is important because cellular synthesis alone does not establish tissue architecture. Researchers therefore consider both production and fiber assembly when examining how repair affects skin, bone, cartilage, tendons, or related tissues.
The process has significance in tissues with different structural and functional demands, including skin, bone, cartilage, and tendons. In medicine, the central concern is not only whether collagen is renewed, but whether the resulting matrix supports the tissue’s structure and function. This broader view helps connect collagen-focused research with dermatological and musculoskeletal conditions.
Medical applications include wound healing, tissue repair, scar management, and regenerative approaches for dermatological and musculoskeletal conditions. These uses reflect different clinical goals, such as supporting restoration after injury or improving tissue organization. The underlying research focus is whether renewed collagen can help restore structure, improve function, and promote more effective healing.
Researchers evaluate biomaterials, cell-based therapies, and other treatments designed to restore tissue structure or support healing. Their assessment centers on how these approaches influence collagen renewal and the resulting tissue organization. This work can be applied to wound repair, scar management, and musculoskeletal or dermatological regeneration, where structural restoration and functional improvement are key outcomes.
