Summary
Breast cancer cells
Area of Science:
- Oncology
- Cancer Biology
- Tumor Microenvironment
Background:
- Tumor progression and treatment response are influenced by the interaction between cancer cells and their microenvironment.
- Cellular plasticity and heterogeneity are key features of the breast cancer ecosystem.
Purpose of the Study:
- To review recent findings on cellular plasticity and heterogeneity in breast cancer.
- To focus on the roles of cancer-associated fibroblasts (CAFs) and tumor-associated macrophages (TAMs).
- To explore therapeutic opportunities targeting the tumor ecosystem.
Main Methods:
- Review of recent scientific literature.
- Analysis of findings from single-cell RNA sequencing studies.
Main Results:
- Breast cancer cells display phenotypic plasticity influenced by genetic and microenvironmental factors.
- Diverse subtypes of CAFs and TAMs exist, with distinct functions and spatial distributions.
- Understanding cellular interactions and niche cues provides therapeutic targets.
Conclusions:
- Targeting cellular phenotypes or niches offers new precision medicine strategies for breast cancer.
- Elucidating tumor ecosystem organization is crucial for advancing cancer treatment.

Cancer Stem Cells and Tumor Maintenance
4.9K
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...

The Tumor Microenvironment
6.6K
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...

Tumor Progression

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...
