Summary
Preeclampsia (PE) involves extracellular matrix (ECM) changes impacting placental development and maternal health. Understanding these ECM alterations, like fibronectin and collagen shifts, is key to new therapies for preeclampsia.
Area of Science:
- Reproductive biology
- Vascular biology
- Obstetrics
Background:
- Preeclampsia (PE) affects 5-10% of pregnancies, causing hypertension and endothelial dysfunction.
- Pathophysiology involves extracellular matrix (ECM) alterations, impacting vascular remodeling and placental development.
- Endothelial dysfunction in PE is linked to antiangiogenic factors like soluble fms-like tyrosine kinase-1 (sFlt-1).
Purpose of the Study:
- To review recent advances in understanding PE pathophysiology.
- Focus on the role of altered ECM components in PE.
- Summarize ECM modifications contributing to endothelial dysfunction in preeclampsia.
Main Methods:
- Comprehensive narrative review of literature from 1994-2024.
- Searched PubMed for articles on PE pathophysiology and ECM modifications.
- Focused on studies linking ECM changes to endothelial dysfunction.
Main Results:
- Reduced matrix metalloproteinase expression and increased collagen fragment XVIII in PE.
- Significant fibronectin alterations and increased heparan sulfate degradation observed.
- Elevated sFlt-1 levels correlate with endothelial dysfunction in preeclampsia.
Conclusions:
- ECM modifications are integral to preeclampsia pathophysiology.
- Specific ECM alterations like fibronectin and collagen changes are associated with PE.
- Understanding these ECM changes offers potential therapeutic targets for improving maternal and fetal outcomes.

2.7K
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...

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.

01:24Overview of Cell-Matrix Interactions
7.0K
The extracellular matrix or ECM holds cells together to form a tissue and allows the cells within the tissue to communicate. ECM comprises proteins such as fibronectin, collagen, laminin, etc. The most abundant protein in this space is collagen. Collagen fibers are interwoven with carbohydrate-containing protein molecules called proteoglycans. ECM allows cell migration and provides a structural scaffold at cell adhesion that anchors the cell when the extracellular matrix proteins interact with...

01:13Cell-matrix's Response to Mechanical Forces
2.5K
In animal cells, the extracellular matrix allows cells within tissues to withstand external stresses and transmits signals from the outside of the cell to the inside. The extracellular matrix is extensive, and its composition varies between different types of tissues. For example, the reticular fibers and ground substance make up the ECM in loose connective tissue, while collagen and bone minerals make up the ECM of bone tissue.

01:23Role of Matrix Metalloproteases in Degradation of ECM
2.3K
Matrix metalloproteases (MMPs) are enzymes involved in the hydrolysis of proteins and glycoproteins of the extracellular matrix. MMPs are essential for the migration and proliferation of cells through the dense matrix network, throughout embryonic development, and throughout morphogenesis. The first MMP activity discovered was a collagenase in a tadpole's tail undergoing metamorphosis. The active collagen deposition and modifications lead to the morphogenesis of tadpoles into the adult...

01:21Matrix Proteoglycans and Glycoproteins
3.8K
Proteoglycans are extensively glycosylated proteins, commonly found in the extracellular matrix, interwoven with collagen fibers. Hyaline cartilage, the most common type of cartilage in the body, consists of short and dispersed collagen fibers associated with large amounts of proteoglycans. These proteoglycans have long negative charges that attract cations, which in turn attract water molecules. This influx of ions and water molecules swells up the proteoglycan like a water-soaked gel that can...
