...ed. They found for the first time that, like their vertebrate
cousins, the fly cell types are replenished by stem cells. Moreover, like vertebrates, the stem cells are multipotent, which means that they can turn into different cell types, and Notch signaling is as essential in flies in controlling which intesti...

UF scientists Throw light on the origin of vertebrate skeleton

evolution that unites us with reptiles, amphibians, sharks and bony fishes, while the lamprey skeleton was based on quite different proteins," said Martin Cohn, Ph.D., a developmental biologist and associate professor with the UF departments of zoolo...

New Studies On Zebrafish Could Aid in Treating Birth Defects
...model that allows us to watch the process of early vertebrate
development and manipulate it. There is no reason why the same approach that we have used with copper cannot work for other nutrients as well," said Gitlin. In fact, applying this approach to other nutrients and other types of birth defects is the ...

neuromuscular junction has been very well studied, and it has long been thought that acetylcholine was the only neurotransmitter used there. “Sometimes people studying development can be misled by knowing how things work in an adult animal,” she ad...
