Summary
Cancer cells exploit cell competition for liver metastasis. This process involves liver progenitor cell compaction, cell-cycle arrest, and differentiation, making them vulnerable to cancer cell outcompetition.
Area of Science:
- Oncology
- Developmental Biology
- Cell Biology
Background:
- Cell competition is crucial for tissue homeostasis and quality control.
- Cancer cells can hijack cell competition for their own benefit, particularly in metastasis.
Purpose of the Study:
- To investigate the impact of cell competition on liver metastasis using mixed murine organoids and microtissues.
- To elucidate the multistage process of metastatic competition in the liver.
Main Methods:
- Generation of mixed murine organoids and microtissues.
- Observation of interactions between liver progenitor cells and intestinal cancer cells.
Main Results:
- Metastatic competition in the liver does not initially induce apoptosis in liver progenitor cells.
- Liver progenitors undergo compaction, cell-cycle arrest, and forced differentiation.
- Newly differentiated liver cells show reduced fitness, enabling outcompetition by intestinal cancer cells.
- Cancer cells utilize diverse epithelial populations in the liver as scaffolds for growth.
Conclusions:
- Tissue-specific cell competition mechanisms are fundamental drivers of metastatic intestinal cancer.
- Cancer cells exploit liver progenitor cells through a multistage process involving differentiation and reduced cellular fitness.

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...

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

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.

2.3K
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,...
