The people behind the papers - Rohit Krishnan Harish and Michael Brand.

The growth factor Fgf8a has been suggested to act as a morphogen during zebrafish gastrulation, spreading from a localized source to form a concentration gradient and impart positional information to cells along a tissue field. In a new paper in Development, Michael Brand and colleagues directly visualize the endogenous Fgf8a gradient in the developing zebrafish embryo. We caught up with the first author Rohit Krishnan Harish, and his PhD supervisor Michael Brand, Professor at the Center for Regenerative Therapies (CRTD) at TU Dresden.
