Zebrafish study yields observation of muscle formation

07.12.2004


Understanding how muscle cells form is crucial to developing new treatments for diseases such as muscular dystrophy and to treating muscle injuries. However, while scientists have focused on muscle cells in culture, they know little about how muscle cells form in a developing embryo.



In this month’s issue of the journal Developmental Cell, Clarissa Henry, assistant professor in the University of Maine Dept. of Biological Sciences, reports findings from a study of muscle cell development in zebrafish embryos. Looking at the formation of two types of muscle fibers, Henry and co-author Sharon L. Amacher of the University of California, Berkeley, describe a process regulated by a gene known as Hedgehog.

The article is titled "Zebrafish Slow Muscle Cell Migration Induces a Wave of Fast Muscle Morphogenesis." It is based on research at the University of California, Berkeley where Henry was a post-doctoral scientist before coming to UMaine.


The authors show that cells leading to the formation of so-called "slow twitch" muscle fibers can induce the formation of "fast twitch" fibers. These two types of fibers differ in their structure and ability to exert force for extended periods of time.

The mechanism of communication between slow and fast twitch cells is unknown, but it is likely, the authors write, that similar examples will be found in other types of tissues.

The findings describe "how fast muscle fibers form in zebrafish, which is a fantastic model system for development in general and muscular dystrophy in particular," says Henry.

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
