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.

The video demonstrates the generation of neurons from adult human dermal fibroblasts (aHDFs). The aHDFs are reprogrammed using a lentiviral vector carrying genes for neuronal transcription factors and short hairpin RNAs (shRNAs). The shRNAs inhibit the expression of a neuronal transcriptional repressor, and the neuronal transcription factors activate genes to differentiate aHDFs into neurons. These reprogrammed aHDFs are cultured in an early and a late neuronal conversion medium to generate...

The goal of this protocol is to establish a 3D in vitro model to study the differentiation of cancer-associated fibroblasts (CAFs) in a tumor bulk-like environment, which can be addressed in different analysis systems, such as immunofluorescence, transcriptional analysis and life cell imaging.
FAQs
Transforming growth factor beta and local tissue conditions act as developmental cues that encourage mesenchymal cells to activate fibroblast-associated gene programs. These signals connect the surrounding environment with changes in cellular identity and extracellular-matrix production. Their influence helps explain how connective tissues respond differently during organ development, normal repair, and conditions involving excessive fibroblast activation.
A key change is activation of fibroblast-associated genes, followed by increased production of structural extracellular-matrix proteins such as collagen and fibronectin. These molecular and functional changes show that progenitor or mesenchymal cells are responding to developmental signals and beginning to contribute to tissue organization. They also provide useful indicators for studying connective-tissue formation and maturation.
Fibroblast activity must be coordinated with tissue formation and repair because extracellular-matrix organization influences tissue architecture. When activation becomes abnormal, the resulting matrix-related changes can disrupt normal architecture and contribute to pathological fibrosis. Comparing regulated development with excessive activation helps researchers distinguish processes that support maturation and healing from those associated with structural damage.
During development, the process links mesenchymal cell behavior to the formation and maturation of connective tissues. As cells acquire fibroblast-associated functions, their production of collagen and fibronectin helps build and organize the extracellular matrix. This developmental connection makes fibroblast differentiation relevant to understanding how tissues establish structure rather than merely how individual cells change identity.
Studies can focus on how mesenchymal cells respond to local signals, when fibroblast-associated gene programs become active, and how extracellular-matrix production changes during tissue formation. Researchers can relate these cellular events to connective-tissue maturation, organ development, and repair after injury. This approach connects molecular responses with larger changes in tissue organization and function.
The process is relevant because fibroblast-associated cells help produce and organize structural matrix components that support tissue architecture. In wound healing, this biology helps frame how injured tissue repairs itself. In tissue engineering, it provides developmental context for designing approaches that reproduce or support connective-tissue formation, while also highlighting the risk that abnormal activation may promote fibrosis.
