Regeneration in Zebrafish

Regeneration in Zebrafish

Instructor:

Focus:

I will be using CREATE in BIO 410 Molecular Cell Biology. This is a senior level elective that includes a three hour/week lab.
The rationales for choosing the topic of regeneration in zebrafish:
1) students express great interest in the topic of regeneration.
2) zebrafish are available for the performing selected methods from the papers in the associated lab.

This class has a lab that meets for three hours/week so my goal will be to incorporate some of the methods we learn and discuss from the articles into an applied learning experience. In past semesters, I have allowed students to design and carry out their own mini research projects in this lab - applying a grant panel activity before mid semester would allow students more thorough feedback before they actual embark on their projects.
