A new cryostat added to the lab

Over the last three years my lab has been using the zebrafish as a model for studying the effects of a diverse group of lens proteins called crystallins on lens development.  You can read more about the evolution of these lens proteins in a previous post.  We just added a new tool to the lab [...]

Zebrafish used to visualize blood stem cell generation

Understanding how blood cells are formed is not only important for developing treatments against numerous diseases, but also teaches us more about the fascinating process of turning stem cells into their specialized descendants.  Recent work suggests that the initial stem cell that produces all of our blood’s formed elements (cells) comes in two flavors.  But [...]
