Summary
Amphibian embryos can recover from damage. Bone morphogenetic proteins (Bmps) and their inhibitors interact to establish the body plan in Xenopus embryos.
Area of Science:
- Developmental biology
- Embryology
- Molecular biology
Background:
- Hans Spemann's experiments revealed amphibians' ability to compensate for embryonic perturbations.
- Understanding the molecular mechanisms underlying embryonic self-regulation is crucial.
Purpose of the Study:
- To uncover the molecular basis of embryonic compensation in amphibians.
- To investigate the role of bone morphogenetic proteins (Bmps) and their inhibitors in establishing the body plan.
Main Methods:
- Studied early Xenopus embryos.
- Analyzed interactions between Bmps and their inhibitors on both dorsal and ventral sides.
Main Results:
- Demonstrated that Bmp signaling and inhibition are key to body plan formation.
- Identified specific interactions critical for embryonic compensation.
Conclusions:
- The balance between Bmp signaling and inhibition is essential for Xenopus embryonic development.
- This study elucidates a fundamental mechanism of embryonic self-regulation.

Endocrine Signaling
68.2K
Endocrine cells produce hormones to communicate with remote target cells found in other organs. The hormone reaches these distant areas using the circulatory system. This exposes the whole organism to the hormone but only those cells expressing hormone receptors or target cells are affected. Thus, endocrine signaling induces slow responses from its target cells but these effects also last longer.

Bacterial Signaling
40.9K
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...

Yeast Signaling
17.3K
Yeasts are single-celled organisms, but unlike bacteria, they are eukaryotes (cells with a nucleus). Cell signaling in yeast is similar to signaling in other eukaryotic cells. A ligand, such as a protein or a small molecule released from a yeast cell, attaches to a receptor on the cell surface. The binding stimulates second-messenger kinases to activate or inactivate transcription factors that further regulate gene expression. Many of the yeast intracellular signaling cascades have similar...

What is Cell Signaling?
131.0K
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 to respond to the environment.

Paracrine Signaling
59.7K
Paracrine signaling allows cells to communicate with their immediate neighbors via secretion of signaling molecules. Such a signal can only trigger a response in nearby target cells because the signal molecules degrade quickly or are inactivated if not taken up. Prominent examples of paracrine signaling include nitric oxide signaling in blood vessels, synaptic signaling of neurons, the blood clotting system, tissue repair/wound healing, and local allergic skin reactions. Nitric oxide as a...

Synaptic Signaling
79.8K
Neurons communicate at synapses, or junctions, to excite or inhibit the activity of other neurons or target cells, such as muscles. Synapses may be chemical or electrical.
