Metastasis

Metastasis

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...

What is Cancer?

What is Cancer?

Cells and tissues must meticulously coordinate their activities for the normal functioning of the human body. Therefore, they exhibit socially responsible behavior - resting, growing, dividing, differentiating, or dying - for the organism’s benefit. Cancer arises when cells divide uncontrollably and invade other tissues or organs.
Although people have known about cancer for centuries, it was only in 1761 that Giovanni Morgagni of Padua performed a detailed autopsy of patients who died from...

Cancer Stem Cells and Tumor Maintenance

Cancer Stem Cells and Tumor Maintenance

Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Adaptive Mechanisms in Cancer Cells

Adaptive Mechanisms in Cancer Cells

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

Cancer Cell Migration through Invadopodia

Cancer Cell Migration through Invadopodia

Invadosome is a broad category of cell surface structures with proteolytic activity that degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However, invadopodia can...

Disorders of Leukocytes

Disorders of Leukocytes

Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...

Summary

Cancer cells migrate using epithelial-mesenchymal transition or amoeboid movement, similar to leukocytes. Understanding these distinct cell migration strategies is key to studying cancer metastasis and immune cell function.

Area of Science:

Cell Biology
Cancer Research
Immunology

Background:

Cancer cells exhibit diverse migratory behaviors.
Some cancer cells adopt fibroblast-like properties via epithelial-mesenchymal transition (EMT).
Increasing evidence suggests other cancer cells utilize amoeboid movement, akin to leukocytes.

Purpose of the Study:

To review and compare the migratory mechanisms of cancer cells and leukocytes.
To explore how both cell types traverse biological barriers like basement membranes and interstitial tissue.
To discuss the processes of vascular entry and exit for these cells.

Main Methods:

Comparative analysis of cellular migration mechanisms.
Review of existing literature on cancer cell and leukocyte motility.

Discussion of the molecular and physical factors influencing cell movement.

Main Results:

Cancer cells and leukocytes share similarities in amoeboid migration.
Differences exist in how cancer cells utilize EMT for migration compared to leukocytes.
Both cell types navigate complex tissue environments and vasculature.

Conclusions:

The ability to switch migratory mechanisms is crucial for cell dissemination.
Understanding these migratory strategies offers insights into cancer metastasis.
This plasticity in cell movement is vital for cells relocating between tissues.
