Cancer cells form cell-in-cell structures through cannibalism and entosis, indicating poor prognosis. This process, driven by metabolic stress, fuels aggressive cancer cell growth and progression.
Area of Science:
- Oncology
- Cell Biology
Background:
- Cell-in-cell structures are prevalent in various cancers.
- Their presence correlates with poor patient prognosis.
Purpose of the Study:
- To discuss the regulation of cell cannibalism and entosis.
- To elucidate how these processes contribute to cancer progression.
Main Methods:
- Review of mechanistic studies on cell-in-cell formation.
- Analysis of regulatory pathways involved in cancer cell ingestion.
Main Results:
- Cancer cells ingest neighboring cells via cannibalism and entosis.
- These processes are linked to metabolic stress and cancer aggressiveness.
Conclusions:
- Cannibalistic activity is a cancer hallmark driven by metabolic stress.
- Cell-in-cell formation fuels aggressive cancer cell phenotypes.

Distinctive Features of Adult Stem Cells vs Cancer Stem Cells
Adult stem cells
Adult stem cells are tissue-specific; hence, they divide to develop the tissue from which they originate. One type of adult stem cell is the epithelial stem cell, which gives rise to the keratinocytes in the multiple layers of epithelial cells in the epidermis of the skin. Adult bone marrow has three distinct types of stem cells:...
