Tracking cells in the regenerating limb through space and time

In order to understand how tissues arise during embryonic development and regeneration, scientists need to find a way to follow different cell lineages in space and time as they divide and migrate. Tzi-Yang Lin, PhD student in the lab of Elly Tanaka, has developed a transgenic frog line to do just that, marking specific cells with a fluorescent protein and tracking their fate. He tells us more about his work, now published in the journal Development, Growth, & Differentiation.
