Key Concepts
Core Developmental Processes
- Cell Division: Mitosis, asymmetric division
- Cell Differentiation: Specialization into cell types
- Cell Migration: Movement during morphogenesis
- Apoptosis: Programmed cell death
- Growth: Cell expansion and division
Signaling in Development
- Autocrine: Cell to itself
- Paracrine: To neighboring cells
- Juxtacrine: Contact-dependent
- Endocrine: Via bloodstream
Types of Development
Direct Development
- No larval stage
- Direct to adult form
Indirect Development
- Egg → Larva → Pupa → Adult
- Complete metamorphosis
- Incomplete metamorphosis
Stem Cells
- Pluripotent: Any cell type (embryonic)
- Multipotent: Related cell types (adult)
- Unipotent: Single cell type
