MSC Seeded Scaffold Preparation: A Technique to Prepare Scaffold Seeded with Mesenchymal Stem Cells for Surgical Implantation into Murine Model

This video describes the technique of seeding mesenchymal stem cells (MSCs) onto a biodegradable poly(lactic acid) (PLA) scaffold. The prepared scaffolds can be implanted into the surgical resection cavity of the brain from where they may migrate towards tumor foci. Further, these cells can be engineered to express therapeutic proteins to stimulate apoptosis in cancer cells.

Seed Structure and Early Development of the Sporophyte

2020
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...

In multicellular organisms, secreted soluble factors elicit responses from different cell types as a result of paracrine signaling. Insert co-culture systems offer a simple way to assess the changes mediated by secreted soluble factors in the absence of cell-cell contact.

A Seed Coat Bedding Assay to Genetically Explore In Vitro How the Endosperm Controls Seed Germination in Arabidopsis thaliana

We present the procedure to assemble a seed coat bedding assay (SCBA) from Arabidopsis thaliana seeds. The SCBA was shown to be a powerful tool to explore genetically and in vitro how the endosperm controls seed germination in dormant seeds and in response to light cues. The SCBA is in principle applicable under any situation where the endosperm is suspected to influence embryonic growth.

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
Cell density affects how many cells can attach, how evenly they distribute, and whether available nutrients support their viability. Too little or uneven placement may produce gaps within a culture or construct, whereas controlled density helps establish a more uniform starting population. Researchers adjust this variable to improve construct consistency and relate cellular organization to later tissue function.
Suspension conditions influence whether cells remain viable before placement and whether they can distribute across a surface or through scaffold pores. Researchers therefore consider the state of the cell suspension alongside density and the selected seeding method. Appropriate control supports attachment and more predictable spatial organization, which is especially important when a construct must develop a consistent cellular arrangement.
Co-seeding introduces two or more defined cell populations into the same culture environment, allowing their spatial arrangement and interactions to become part of the engineered system. This approach can help researchers examine how distinct cell types contribute together to tissue organization and function. It also supports models in which cellular relationships are important for studying tissue behavior.
The available architecture of the culture surface, biomaterial scaffold, or engineered tissue construct strongly influences cellular distribution. Surface-based systems emphasize coverage across an accessible area, while porous materials provide internal spaces that cells may occupy. Seeding conditions must therefore be matched to the construct’s available surfaces or pores so cells can attach, remain viable, and access nutrients.
A typical workflow begins by selecting the culture surface, scaffold, or engineered construct and defining the cell population or populations to be used. Researchers then adjust cell density and suspension conditions, apply an appropriate seeding method, and allow placement to establish attachment and distribution. The resulting arrangement is evaluated for uniformity, viability, and suitability for the intended model.
Cell Type Seeding is useful when a study requires cells to populate a tissue construct, biomaterial scaffold, organoid model, or other three-dimensional culture. It also supports in vitro disease and drug studies by establishing a controlled cellular starting arrangement. These applications allow researchers to investigate how organization and interactions among cell populations relate to tissue behavior or experimental responses.
Reproducible seeding produces a more consistent initial distribution of cells between experiments and across engineered constructs. That consistency improves comparisons of growth, organization, and tissue-related function, while reducing uncertainty caused by variable starting conditions. In disease or drug models, controlled placement can also help researchers connect observed responses to the experimental treatment rather than to differences in cellular arrangement.
