We report an efficient and simple method to isolate embryos at early stages of development from Arabidopsis thaliana seeds. Up to 40 embryos can be isolated in 1 hr to 4 hr, depending on the downstream application. The procedure is suitable for transcriptome, DNA methylation, reporter gene expression, immunostaining and fluorescence in situ hybridization analyses.

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...

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-cell adhesion causes seeded pluripotent stem cells to compact into a cohesive aggregate. As the structure grows, nutrients and signaling molecules become distributed unevenly across its interior, creating spatial gradients. These gradients expose cells in different regions to distinct local conditions, which can influence developmental behavior and help researchers examine how organization emerges in a controlled three-dimensional culture system.
Seeding density, culture time, and differentiation cues are central variables. The number of cells initially introduced affects aggregate formation, while the duration of culture changes the developmental state reached by the structure. Researchers can also adjust differentiation signals to influence lineage commitment, allowing the resulting material to be tailored for reproducible downstream experiments.
Three-dimensional aggregation provides cellular organization that is not represented as directly in a two-dimensional culture. Compaction creates an aggregate with spatially varying nutrient and signaling conditions, enabling investigators to study early developmental processes in a more organized cellular setting. Embryo body seeding therefore serves as an intermediate approach between simpler two-dimensional systems and more complex tissue-formation models.
A typical workflow begins by preparing a defined number of pluripotent stem cells and placing them in a low-adhesion or suspension culture. Cells then interact through cell-cell adhesion and compact into aggregates during controlled culture. Investigators regulate culture time and differentiation cues before collecting the resulting material for downstream assays or other bioengineering analyses.
Researchers apply the method when they need a controlled three-dimensional model for studying tissue formation or early development. It can also generate reproducible material for disease modeling and drug screening. In bioengineering, the approach helps connect cell culture conditions with emerging spatial organization, making it useful for examining how cellular aggregates develop into more structured systems.
Embryoid bodies can provide material for downstream assays that examine how culture conditions affect lineage commitment and early developmental organization. Because investigators control seeding density, culture duration, and differentiation cues, they can compare how these variables alter outcomes across experiments. This supports developmental biology, disease modeling, drug screening, and studies of tissue formation under laboratory conditions.
