Establishment of a new human lymphoma line that secretes plasminogen activator
Japanese Journal of Cancer Research : Gann
|January 1, 1985
Abstract:
A new cell line, designated RC-K8, was established from the peritoneal effusion of a patient with histiocytic lymphoma. The RC-K8 had human male karyotype with 14q+ and was found to have B-cell (B1) and monocyte/macrophage (intracytoplasmic alpha subunit of S-100 protein) markers. A fibrin plate method demonstrated that RC-K8 cells release plasminogen activator in culture.
Insights
A novel cell line, RC-K8, derived from histiocytic lymphoma, exhibits characteristics of both B-cells and monocyte/macrophages. These cells were observed to release plasminogen activator, indicating potential roles in cellular processes.
Area of Science:
- Oncology
- Cell Biology
- Hematology
Background:
- Histiocytic lymphoma is a rare malignancy.
- Establishing new cell lines is crucial for studying cancer biology.
- Understanding cell line characteristics aids in research.
Purpose of the Study:
- To establish and characterize a new human cell line from histiocytic lymphoma.
- To investigate the phenotypic and functional properties of the RC-K8 cell line.
Main Methods:
- Cell line establishment from patient peritoneal effusion.
- Karyotyping to determine chromosomal abnormalities.
- Immunophenotyping for cell markers (B-cell, monocyte/macrophage).
- Fibrin plate assay to assess plasminogen activator release.
Main Results:
- The RC-K8 cell line was successfully established.
- RC-K8 cells possess a human male karyotype with a 14q+ abnormality.
- Cells expressed B-cell (B1) and monocyte/macrophage markers (intracytoplasmic S-100 protein alpha subunit).
- RC-K8 cells demonstrated the release of plasminogen activator in culture.
Conclusions:
- RC-K8 represents a unique human cell line with hybrid B-cell and monocyte/macrophage features.
- The cell line's ability to release plasminogen activator suggests potential involvement in matrix remodeling or other cellular functions.
- RC-K8 provides a valuable model for studying histiocytic lymphoma and related cellular processes.
