Epidermis and dermis5
- The integument consists of 2 mutually dependent layers, the epidermis and dermis, which rest on a fatty subcutaneous layer, the panniculus adiposus. (medscape.com)
- Teeth, hair, and hair follicles are formed by the epidermis and dermis in concert, while fingernails and toenails are formed by the epidermis alone. (medscape.com)
- The thickness of the epidermis and dermis in the vitamin extracts (Vit)- and SFB-treated group was lower than that in the vehicle-treated group, but the group treated with SFB50 was the most effective group. (nih.gov)
- The epidermis and dermis are the 2 main layers of the skin. (cancer.ca)
- The separation between epidermis and dermis occurs at the basement membrane zone, located just inferior to the basal cell keratinocytes. (cancer.gov)
Collagen35
- The dermis is derived primarily from mesoderm and contains collagen, elastic fibers, blood vessels, sensory structures, and fibroblasts. (medscape.com)
- Structural components of the dermis are collagen, elastic fibers, and extrafibrillar matrix. (wikipedia.org)
- Apart from these cells, the dermis is also composed of matrix components such as collagen (which provides strength), elastin (which provides elasticity), and extrafibrillar matrix, an extracellular gel-like substance primarily composed of glycosaminoglycans (most notably hyaluronan), proteoglycans, and glycoproteins. (wikipedia.org)
- The reticular dermis is the lower layer of the dermis, found under the papillary dermis, composed of dense irregular connective tissue featuring densely-packed collagen fibers. (wikipedia.org)
- The orientation of collagen fibers within the reticular dermis creates lines of tension called Langer's lines, which are of some relevance in surgery and wound healing. (wikipedia.org)
- Methods: We performed biochemical and molecular analysis of type I (pro-) collagen in a cohort of seven patients referred with a clinical diagnosis of EDS and showing only subtle signs of OI. (amrita.edu)
- The COL7A1 gene provides instructions for making a protein called pro-α1(VII) chain that is used to assemble a larger protein called type VII collagen. (medlineplus.gov)
- In particular, type VII collagen plays an essential role in strengthening and stabilizing the skin. (medlineplus.gov)
- Then the molecules arrange themselves into long, thin bundles of mature type VII collagen. (medlineplus.gov)
- Type VII collagen is the major component of structures in the skin called anchoring fibrils. (medlineplus.gov)
- These mutations alter the structure or disrupt the production of the pro-α1(VII) chain protein, which affects the production of type VII collagen. (medlineplus.gov)
- When type VII collagen is abnormal or missing, anchoring fibrils cannot form properly. (medlineplus.gov)
- Most of the COL7A1 gene mutations responsible for RDEB-sev gen result in production of abnormally short pro-α1(VII) chains that cannot form type VII collagen. (medlineplus.gov)
- As a result, little type VII collagen is available to make anchoring fibrils. (medlineplus.gov)
- Many of these genetic changes alter the structure of the pro-α1(VII) chain protein such that it cannot form normal type VII collagen. (medlineplus.gov)
- In many cases, these mutations alter a part of type VII collagen known as the triple helical domain. (medlineplus.gov)
- This region gives type VII collagen its usual triple-stranded structure. (medlineplus.gov)
- Mutations that substitute other amino acids for glycine in this region can disrupt the triple-stranded structure of type VII collagen. (medlineplus.gov)
- When the abnormally shaped collagen molecules are incorporated into anchoring fibrils, they interfere with the fibrils' normal function and prevent them from effectively connecting the epidermis and the dermis. (medlineplus.gov)
- DDEB can also be caused by other types of mutations, particularly changes that affect the folding of type VII collagen. (medlineplus.gov)
- Some research has suggested that abnormal forms of type VII collagen that retain a procollagen fragment called the NC1 domain may increase the risk of tumor formation. (medlineplus.gov)
- Collagen and elastin are proteins in the dermis that give skin strength, sturdiness, stretch and flexibility. (cancer.ca)
