A cell line (HBL-100) established from human breast milk
Cell and Tissue Research
|January 1, 1982
Summary
Researchers established a continuous human milk cell line (HBL-100) from healthy donors. This transformed cell line displays characteristics like soft agar colony formation and aneuploidy, useful for breast cancer research.
Area of Science:
- Cell Biology
- Human Milk Research
- Cancer Cell Line Development
Background:
- Primary cell cultures from human milk offer a unique source for biological studies.
- Understanding cell transformation is crucial for cancer research.
Purpose of the Study:
- To establish and characterize a continuous cell line from human milk.
- To investigate the potential transformation characteristics of these cells.
Main Methods:
- Isolation and culture of cells from early lactation human milk.
- Karyotype analysis to assess chromosomal complement.
- Soft agar assays to evaluate colony formation ability.
- Electron microscopy to observe cellular structures like desmosomes and tonofibrils.
Main Results:
- Successfully established a continuous cell line designated HBL-100.
- Karyotype analysis revealed a marker chromosome and aneuploidy.
- HBL-100 cells demonstrated anchorage-independent growth (soft agar colonies).
- Observed desmosomes and cytoplasmic tonofibrils in early passages.
Conclusions:
- The HBL-100 cell line, derived from normal human milk, exhibits characteristics of cellular transformation.
- This cell line represents a valuable model for studying human breast epithelial cells and potential oncogenic pathways.
