Abstract
Abstract
Background:
In-vitro model systems provide an important tool in breast cancer research and, over recent years, there have been considerable advances in their construction. However, despite these advances, the majority of models still employ a narrow range of established cell lines, which frequently are not appropriate for the in-vivo cell type they are representing1.
Method:
As part of the Breast Cancer Campaign Tissue Bank, we have developed a cell culture programme which feeds into the main tissue collection and involves the systematic generation of materials from normal, high-risk, cancer-containing and malignant breast tissue in order to make available a breadth of material to the research community.
Following informed patient consent, fresh tissue is retrieved and, using tissue digestion and magnetic bead technology2, purified cell populations are isolated, characterized and frozen down, or further processed for DNA and RNA isolation.
Results:
We have isolated purified populations of luminal epithelial, myoepithelial and fibroblast cells from normal breast, risk-reduction (BRCA1 and BRCA2 mutated) breast and from morphologically normal breast tissue surrounding breast cancer. We have generated matched surround and tumour-associated fibroblasts, as well as matched tumour epithelial and tumour-associated fibroblast cell isolates.
These cells have been incorporated into 2- and 3-D culture models and we have demonstrated successful genetic manipulation, with siRNA gene knockdown and gene over-expression through retroviral transduction. Immortalisation of selected cell populations is currently underway.
Intact organoids and tissue explants have also been generated for in-vitro experimentation. Matched frozen and FFPE samples are available, together with full clinicopathological data. The research community can access these biomaterials via a web-based search portal, with full user support.
Conclusion:
Through this cell culture programme we aim to make available a wider and more appropriate range of materials for breast research, which should allow more clinically relevant model systems to be developed and add value to breast cancer biobanking.
