The chemical composition and biological activity of and are scarcely investigated. In this study, the nutritional and chemical profiles of and , considering their different morphological parts (leaves, fruits and roots), were assessed together with their antioxidant and antibacterial potential. Our results showed that carbohydrates are the major macronutrients in both species (above 62 g/100 g dry weight-DW).

- - Stem cell-based embryo models are essential for studying early human development, but their effectiveness depends on how closely they mimic real embryos at the molecular, cellular, and structural levels.
- - Researchers created a comprehensive reference dataset by integrating six existing datasets that track human development from the zygote stage to the gastrula stage, providing a benchmark for comparing human embryo models.
- - Using an advanced analysis method called stabilized Uniform Manifold Approximation and Projection, the new reference helps identify cell types in various embryo models, revealing potential misannotations without proper reference comparisons.
