While experiments performed in tissue culture can be informative and suggest functional principles that can be verified in vivo, it is known that large changes occur in gene expression of cells in culture11,12 . In order to avoid a tissue culture step when profiling gene expression in fibroblasts, we developed a protocol that allows isolation of normal, as well as cancer-associated fibroblasts from fresh mouse or human tissue. This protocol was successfully applied with skin, pancreas and breast tissu...

isolation of normal and cancer-associated fibroblasts from fresh tissues by fluorescence activated cell sorting (facs)

Cancer-associated fibroblasts (CAFs) are the most prominent cell type within the tumor stroma of many cancers, in particular breast carcinoma, and their prominent presence is often associated with poor prognosis1,2. CAFs are an activated subpopulation of stromal fibroblasts, many of which express the myofibroblast marker &alpha;-SMA3. CAFs originate from local tissue fibroblasts as well as from bone marrow-derived cells recruited into the developing tumor and adopt a CAF phenotype under the influence of the tumor microenvironment4. CAFs were shown to facilitate tumor initiation, growth and progression through signaling that promotes tumor cell proliferation, angiogenesis, and invasion5-8. We demonstrated that CAFs enhance tumor growth by mediating tumor-promoting inflammation, starting at the earliest pre-neoplastic stages9. Despite increasing evidence of the key role CAFs play in facilitating tumor growth, studying CAFs has been an on-going challenge due to the lack of CAF-specific markers and the vast heterogeneity of these cells, with many subtypes co-existing in the tumor microenvironment10. Moreover, studying fibroblasts in vitro is hindered by the fact that their gene expression profile is often altered in tissue culture11,12 . To address this problem and to allow unbiased gene expression profiling of fibroblasts from fresh mouse and human tissues, we developed a method based on previous protocols for Fluorescence-Activated Cell Sorting (FACS)13,14. Our approach relies on utilizing PDGFR&alpha; as a surface marker to isolate fibroblasts from fresh mouse and human tissue. PDGFR&alpha; is abundantly expressed by both normal fibroblasts and CAFs9,15 . This method allows isolation of pure populations of normal fibroblasts and CAFs, including, but not restricted to &alpha;-SMA+ activated myofibroblasts. Isolated fibroblasts can then be used for characterization and comparison of the evolution of gene expression that occurs in CAFs during tumorigenesis. Indeed, we and others reported expression profiling of fibroblasts isolated by cell sorting16. This protocol was successfully performed to isolate and profile highly enriched populations of fibroblasts from skin, mammary, pancreas and lung tissues. Moreover, our method also allows culturing of sorted cells, in order to perform functional experiments and to avoid contamination by tumor cells, which is often a big obstacle when trying to culture CAFs.

Using PDGFR&alpha; as a marker for fibroblasts results in isolation of highly enriched populations of tissue fibroblasts. The level of purity after sorting was 99%, as quantified by post-sort analysis (Figure 2A). Estimating the percentage of contaminating non-fibroblast cells by the relative expression of cell-specific control genes (Figure 2B) typically shows 0.1-0.6% contamination. This level of purity allows high quality transcriptome profiling of isolated fibroblasts9.</p...
