5 Questions
What are the main processes involved in the embryonic development of animals according to developmental biology?
Tissue patterning, tissue growth, and tissue morphogenesis
What does regional specification refer to in the context of embryonic development?
The processes that create the spatial patterns in a ball or sheet of initially similar cells
What are the defined cell populations in the early stages of regional specification?
Cell populations committed to developing to a specific region or part of the organism
What is involved in the early stages of regional specification?
The action of cytoplasmic determinants located within parts of the fertilized egg and inductive signals emitted from signaling centers in the embryo
What does developmental biology encompass in addition to the study of animal and plant growth and development?
The biology of regeneration, asexual reproduction, metamorphosis, and the growth and differentiation of stem cells in the adult organism
Study Notes
Developmental Biology
- The study of growth and development in animals and plants, including regeneration, asexual reproduction, metamorphosis, and stem cell growth and differentiation in adults.
Embryonic Development
- Involves three main processes: tissue patterning, tissue growth, and tissue morphogenesis.
- Tissue patterning is achieved through regional specification and patterned cell differentiation.
- Regional specification creates spatial patterns in a ball or sheet of initially similar cells through:
- Cytoplasmic determinants in the fertilized egg.
- Inductive signals from signaling centers in the embryo.
- Early stages of regional specification commit cell populations to developing specific regions or parts of the organism, but do not generate functional differentiated cells.
