Summary
Embryo development is regulated by mechanics. This study introduces
Area of Science:
- Developmental biology
- Mechanobiology
- Cell biology
Background:
- Mechanics regulate cell behavior and embryo development.
- Focus has been on cell properties affecting cell behavior.
- Limited understanding of dynamic tissue mechanics regulation in embryos.
Purpose of the Study:
- Discuss the role of mechanosignalling in embryonic development.
- Propose understanding dynamic tissue mechanics regulation as crucial.
- Introduce and define 'actuation' as a novel concept in embryo mechanobiology.
Main Methods:
- Literature review and conceptual synthesis.
- Analysis of existing examples in developmental biology.
- Theoretical framework development for 'actuation'.
Main Results:
- Mechanosignalling is a key regulator in development.
- 'Actuation' proposed as a process where cell populations alter adjacent tissue mechanics.
- Examples of embryonic actuation and mechanical feedback are discussed.
Conclusions:
- Dynamic tissue mechanics regulation is vital in embryo mechanobiology.
- Actuation parallels chemical signaling in embryonic induction.
- Further research into actuation and mechanical feedback is warranted.

01:23Overview of Cell Signaling
19.8K
Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. Additionally, cells often need to communicate with one another. Unicellular and multicellular organisms use a variety of cell signaling mechanisms to communicate with the environment.
Cells respond to many types of information, often through receptor proteins positioned on the membrane. For example, skin cells respond to and transmit touch...

02:19Morphogenesis
23.4K
Plant morphogenesis—the development of a plant’s form and structure—involves several overlapping developmental processes, including growth and cell differentiation. Precursor cells differentiate into specific cell types, which are organized into the tissues and organ systems that make up the functional plant.

01:21Chemotaxis and Direction of Cell Migration
3.3K
Cells can detect chemical cues in their environment and reorganize the cytoskeleton to migrate toward them or away from them. This directional migration, called chemotaxis, is essential during embryogenesis and development, immune response, tissue repair and regeneration, and reproduction. These chemical cues can either attract or repel the cell's movement. For example, axon development is determined by a combination of chemoattractants and chemorepellents that direct the growing axon...

01:51Determination
17.2K
During embryogenesis, cells become progressively committed to different fates through a two-step process: specification followed by determination. Specification is demonstrated by removing a segment of an early embryo, “neutrally” culturing the tissue in vitro—for example, in a petri dish with simple medium—and then observing the derivatives. If the cultured region gives rise to cell types that it would normally generate in the embryo, this means that it is specified. In...

01:26Introduction to Special Senses
5.4K
Sensory receptors play an integral part in comprehending our external and internal environments. They receive diverse stimuli, converting them into the nervous system's electrochemical signals. This conversion occurs as the stimulus alters the sensory neuron's cell membrane potential, instigating the generation of an action potential. This action potential is subsequently transmitted to the central nervous system (CNS), which integrates with other sensory data or higher cognitive...

03:14Notch Signaling Pathway
4.1K
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...
