As discussed in the Model Organisms II video “An Introduction to the Chick: Gallus gallus domesticus,” chick embryos are frequently used for cancer research. For example, transplanted human cancer cells can be used to establish tumors in the embryos, in which the spread of cancerous cells can be easily studied.

For students and scientists beginning animal-based lab work, seeing a research procedure performed by experts is by far the most effective method of learning. Now the Cambridge-based company, JoVE, has released a new online video-based tool, Model Organisms II, to revolutionize the teaching of fundamental experiments in the three most common laboratory organisms—the mouse, chick and zebrafish.

"Each of these species makes unique demands upon researchers, both in terms of the steps required for their maintenance and reproduction, as well as the tools and techniques available to study them," said Aaron Kolski-Andreaco, PhD., JoVE's Chief Product Officer, "The Model Organisms II collection provides a great overview of these nuances, in addition to providing visual demonstrations of techniques essential to working with each model."

Contrary to the traditional, text-based educational materials, Model Organisms II presents a powerful combination of scientific animation with video demonstrations by scientists from leading around the world. This novel tool is the latest installment in JoVE Science Education database dedicated to teaching laboratory fundamentals through simple, easy-to-understand visual presentations. For universities and colleges, the JoVE Science Education videos are a valuable new resource for efficient teaching and research.

"I wanted to find justification for buying it, so I sent around a message to faculty in biology," said Michael Newman, a Head Librarian and Bibliographer at Stanford University, "Those things usually don't get much response, but this time I got some pretty enthusiastic replies."

Zebrafish are very useful for modeling inheritable human diseases. Disease states are easily reproduced in zebrafish embryos by microinjecting them to alter protein expression. This technique is demonstrated in Model Organisms II, using the example of a zebrafish model of muscular dystrophy. The resulting organisms exhibit an abnormal response to touch.

Stanford subscribed to the JoVE Science Education database in December 2013, shortly after JoVE released this database. Over 100 institutions—including those ranging from the Ivy League to community colleges—also purchased a subscription within only three months following the product launch.

Among other things, mice can be used to study how the brain records and recalls memories. In this test of spatial memory seen in Model Organisms II, mice are trained to use visual cues to locate a platform and escape from a pool of water. Credit: The Journal of Visualized Experiments

"I've used it as a class tool where students can watch a technique on the screen and then do it immediately afterwards, and for what they're going to do the next time the class meets, so they'll come in a little less blind," said assistant professor, Dr. Jason Kuehner of Emmanuel College in Boston, MA, "For something like western blotting this is really good. That's a fairly laborious technique with multiple steps, and for students it's very easy to get confused as to what each step in the protocol means."
