Carcinoma-associated fibroblasts (CAFs) rich in myofibroblasts present within the tumour stroma, play a major role in driving tumour progression. We developed a coimplantation tumour xengraft model for experimentally generating CAFs from human mammary fibroblasts. The protocol describes how to establish CAF myofibroblasts that acquire an ability to promote tumourigenesis.

Seed Structure and Early Development of the Sporophyte

Seed structures are composed of a protective seed coat surrounding a plant embryo, and a food store for the developing embryo. The embryo contains the precursor tissues for leaves, stem, and roots. The endosperm and cotyledons—seed leaves—act as the food reserves for the growing embryo. The embryo contains a double set of chromosomes, one set from each parent. Fertilization of the haploid egg by the haploid sperm gives rise to the zygote, which develops into the embryo. The endosperm is a...

A simple method is described for analyzing effects of tissue fibroblasts on associated epithelial cells. The combination of this method and three-dimensional tissue culture can facilitate analysis of cells after isolation from 3D. The technique is applicable to cells of varying malignant potential, allowing systematic study of effects of tumor-associated stroma on tumor cells.
FAQs
Communication occurs through several coordinated routes rather than a single signal. Direct cell contact can affect epithelial behavior, while secreted signaling molecules provide additional messages between the two cell populations. Fibroblasts also remodel the extracellular matrix, changing the surrounding environment. Together, these mechanisms can alter epithelial adhesion, proliferation, migration, and phenotype in ways relevant to tissue organization and cancer biology.
Extracellular matrix remodeling provides a mechanism by which fibroblasts can influence epithelial cells beyond direct contact or secreted signals. Changes in the matrix may affect how epithelial cells attach, organize, move, or maintain their phenotype. Examining this component helps researchers evaluate stromal contributions to epithelial behavior and better represent interactions that occur in normal or tumor tissue.
The method can be used to examine changes in epithelial cell adhesion, proliferation, migration, and phenotype. These outcomes represent different aspects of cell behavior: attachment, population expansion, movement, and cellular characteristics. Assessing them together helps reveal whether fibroblast interactions primarily affect tissue organization, support potentially harmful behavior, or contribute to epithelial transformation and invasion in cancer-related models.
A basic workflow begins by selecting fibroblast and epithelial cell populations, bringing them together under controlled laboratory conditions, and allowing their interactions to develop. Researchers then assess changes in epithelial behavior and tissue organization, including adhesion, proliferation, migration, or phenotype. The design can represent normal or tumor tissue, depending on the biological interaction being investigated.
This approach is useful when the research question concerns how surrounding stromal cells affect epithelial or cancer cell behavior. It can help investigate fibroblast support of epithelial transformation, invasion, or treatment responses, while also modeling interactions within the tumor microenvironment. The resulting system connects cellular signaling and matrix effects with cancer-relevant changes that may be missed in epithelial-only studies.
Fibroblast epithelial seeding can provide evidence about how stromal interactions influence epithelial behavior and tissue organization. Researchers may use the model to evaluate transformation, invasion, or responses to treatment, and to examine signaling between cell populations. These observations can also inform therapeutic strategies aimed at disrupting interactions between cancer cells and the surrounding stroma rather than targeting epithelial cells alone.
