Metastasis02:30

Metastasis

5.6K
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Cadherins in Tissue Organization01:19

Cadherins in Tissue Organization

3.0K
The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.

Cell Migration01:19

Cell Migration

4.9K
Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.

The Extracellular Matrix01:29

The Extracellular Matrix

9.1K
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...

Mesenchymal Stem Cells01:19

Mesenchymal Stem Cells

4.8K
Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their...

The Tumor Microenvironment02:17

The Tumor Microenvironment

6.7K
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...

Area of Science:

  • Cell Biology
  • Developmental Biology
  • Cancer Biology

Background:

  • Epithelial-mesenchymal transition (EMT) is a fundamental biological process where epithelial cells lose their characteristics and gain migratory and invasive properties.
  • EMT plays critical roles in embryonic development, wound healing, and tissue regeneration.
  • Aberrant EMT is implicated in cancer progression, metastasis, and drug resistance.

Discussion:

  • The molecular mechanisms governing EMT involve complex signaling pathways and transcription factors.
  • Identifying key regulators of EMT is essential for understanding its diverse roles.
  • The plasticity of EMT allows cells to switch between epithelial and mesenchymal states.

Key Insights:

  • EMT is a dynamic process regulated by a network of signaling pathways.
  • Specific transcription factors orchestrate the cellular changes during EMT.
  • EMT contributes significantly to the invasive and metastatic potential of cancer cells.

Outlook:

  • Targeting EMT pathways offers potential therapeutic strategies for cancer and fibrotic diseases.
  • Further research into EMT regulation could reveal novel biomarkers for disease diagnosis and prognosis.
  • Understanding the interplay between EMT and the tumor microenvironment is crucial for effective treatment development.
