Summary
Extracellular matrix (ECM) proteins are crucial for tissue biophysical properties. Alterations in ECM genes or functions cause skin disorders, revealing that the entire ECM functional unit, not just single proteins, causes disease.
Area of Science:
- Biochemistry
- Dermatology
- Molecular Biology
Background:
- Extracellular matrix (ECM) proteins primarily understood for structural roles and network assembly.
- Interactions within ECM networks dictate tissue biophysical properties.
- Dysfunction in ECM molecules impacts tissue integrity and function.
Purpose of the Study:
- To review how genetic or functional alterations in ECM molecules lead to skin disorders.
- To explore the concept of ECM functional units in disease pathogenesis.
- To highlight therapeutic developments stemming from understanding ECM disease mechanisms.
Main Methods:
- Literature review focusing on ECM proteins, genetic alterations, and skin disorders.
- Analysis of disease mechanisms involving ECM gene mutations and enzyme modifications.
- Examination of emerging therapeutic strategies for ECM-related diseases.
Main Results:
- Skin disorders arise from alterations in ECM genes, modifying enzymes, or biological functions.
- Similar clinical symptoms can result from different causative genes, indicating a failure of the ECM functional unit.
- Understanding disease pathways has spurred novel therapies for rare genetic skin disorders.
Conclusions:
- ECM-related skin disorders result from the malfunction of the entire ECM functional unit.
- This understanding facilitates new therapeutic approaches for connective tissue diseases.
- Targeting ECM functional units offers promise for treating common and rare skin conditions.

01:29The Extracellular Matrix
Overview
In order to maintain tissue organization, many animal cells are surrounded by structural molecules that make up the extracellular matrix (ECM). Together, the molecules in the ECM maintain the structural integrity of tissue as well as the remarkable specific properties of certain tissues.
Composition of the Extracellular Matrix
The extracellular matrix (ECM) is commonly composed of ground substance, a gel-like fluid, fibrous components, and many structurally and functionally diverse...

01:26Extracellular Matrix
Unlike epithelial tissue, which is composed of cells closely packed with little or no extracellular space in between, connective tissue cells are dispersed in a matrix. This extracellular matrix (ECM) is composed of fibrous proteins like collagen, elastin, and fibronectin in a ground substance consisting of interstitial fluid, cell adhesion proteins, and proteoglycans. The proteoglycans form a gel-like material in the spaces between cells and provide hydration, buffering, binding, and force...
01:15Reticular Dermis
The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.

01:13Collagens 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.

Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
