Abstract

Objective:

Aim: To study peculiarities of the state of extracellular matrix in testicular embryonal carcinoma.

Patients And Methods:

Materials and Methods: Samples of testicular embryonal carcinoma tissue were collected from 3 groups of patients (group «1» - stages T1N0S0-2, group «2» - T2N1-3S0-2, group «3» - T2-3N0-3S0-2 with distant metastases) to assess the state of its extracellular matrix investigating MMP-1, MMP-3 and MMP-9 expression.

Results:

Results: The levels of MMP-1, MMP-3 and MMP-9 expression were statistically significantly higher in patients with tumorous vascular/lymphatic invasion, metastases in regional lymph nodes, distant metastases and invasion into the spermatic cord (except of lightness of MMP-3 expression) in comparison with patients without these characteristics.

Conclusion:

Conclusions: MMP-1, MMP-3 and MMP-9 are involved in carcinogenesis already at the early stages of embryonal carcinoma and at the transition to late stages there is an increase of their synthesis, what proves their significant role in the destruction of extracellular matrix, invasion and metastatic process. Studied MMPs can be regarded as a prognostic factors of the embryonal carcinoma course as well as a potentially important therapeutic targets.

Extracellular Matrix

Extracellular 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...

Embryonic Connective Tissues

Embryonic Connective Tissues

During early development, the embryo forms two types of connective tissues— the mesenchyme and mucoid connective tissue.
The mesenchyme is the first connective tissue that emerges in the developing embryo. It consists of loosely arranged multipotent mesenchymal cells and reticular fibers in the extracellular matrix. This loose arrangement allows easy migration of cells, which is essential for germ layer positioning, patterning, and organ morphogenesis during embryonic development.

The Tumor Microenvironment

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Testes: Histology

Testes: Histology

A tough, fibrous membrane, the tunica albuginea, covers the testes, extending inward to form fibrous partitions or septa, dividing them into internal compartments called lobules. Each lobule has 1 to 3 tightly coiled seminiferous tubules where sperm production occurs. These tubules merge into a tubular network at the back of the testis, known as the rete testis. It connects to 15 to 20 efferent ductules, leading to the epididymis.
The spermatogenic cells, responsible for producing sperm, are...

The Extracellular Matrix

The 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...

Cell-matrix's Response to Mechanical Forces

Cell-matrix's Response to Mechanical Forces

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.
Anchoring junctions mechanically attach a cell to the...
