Key Concepts
Developmental Stages
Model Organisms
- C. elegans: Fixed cell lineage
- Drosophila: Genetic model
- Zebrafish: Transparent embryos
- Xenopus: External development
- Mouse: Mammalian model
Pattern Formation
Morphogens
- BMP: Bone morphogenetic protein
- Wnt: Cell fate specification
- Hedgehog: Segmentation
- FGF: Growth and patterning
- Shh: Sonic hedgehog
Gene Regulatory Networks
# Example: Segment polarity network (simplified)
segment_polarity_network = {
'engrailed': 'activated_by_en',
'wingless': 'expressed_in_anterior',
'hedgehog': 'expressed_in_posterior'
}
# Key: Cell-cell communication controls segment pattern
Key Processes
- Fertilization and zygote formation
- Cleavage and blastula formation
- Gastrulation: Germ layer formation
- Neurulation: Nervous system formation
- Organogenesis: Organ formation
- Metamorphosis: Body plan changes
