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...

Fibroblast behavior underlies a spectrum of clinical entities, but they remain poorly characterized, largely due to their inherent heterogeneity. Traditional fibroblast research relies upon in vitro manipulation, masking in vivo fibroblast behavior. We describe a FACS-based protocol for the isolation of mouse skin fibroblasts that does not require cell culture.

Introduction to Seed Plants

Most plants are seed plants—characterized by seeds, pollen, and reduced gametophytes. Seed plants include gymnosperms and angiosperms. Gymnosperms—cycads, ginkgo biloba, gnetophytes, and conifers—typically form cones. The pollen cones contain male gametophytes. The ovulate cones contain female gametophytes and form exposed seeds when fertilized. Angiosperms, the most diverse and ubiquitous group of land plants, form flowers, and fruit. Like the cones of gymnosperms, the flowers and fruit of...
FAQs
Seeding density influences how many fibroblasts occupy a given culture area or scaffold volume, which can affect the resulting distribution and the ability to evaluate construct development. A defined density provides a controlled starting condition, allowing comparisons among biomaterials or engineered constructs and helping researchers interpret differences in attachment, spreading, proliferation, and matrix deposition.
In three-dimensional constructs, distribution is important because cells must be present across the scaffold rather than concentrated in a single region. More uniform placement supports assessment of cell-material interactions throughout the construct and makes observations of viability, extracellular matrix deposition, and maturation more representative of the engineered environment.
Fibroblast activity matters beyond initial attachment because these cells produce extracellular matrix components that contribute to scaffold remodeling and tissue-like development. Monitoring their spreading, proliferation, and matrix deposition therefore connects early cell behavior with later construct maturation. This relationship helps bioengineers judge whether a material supports the intended cellular and structural response.
A typical workflow begins with fibroblasts prepared as a cell suspension, followed by application of a defined seeding density to a culture surface or three-dimensional scaffold. The construct is then maintained under conditions that promote attachment, spreading, and proliferation. Consistency at each stage helps establish comparable starting populations across experiments.
Fibroblast Seeding is useful when researchers evaluate biomaterials, engineered tissue constructs, or cell-material interactions. In each case, the technique establishes a cellular component whose behavior can be examined alongside the material or scaffold. The resulting observations can inform assessments of viability, extracellular matrix deposition, scaffold remodeling, and overall construct maturation.
Key outcomes include cell viability, distribution, matrix deposition, and construct maturation. Uniform initial placement improves reproducibility, while attachment, spreading, and proliferation reveal how the fibroblasts respond to the culture surface or scaffold. Together, these measurements help distinguish differences in construct performance from variation introduced during the initial seeding step.
