In animals, many cells reach their destinations by migrating toward higher concentrations of an attractant. However, the nature, generation, and interpretation of attractant gradients are poorly understood. Using a GFP fusion and a signaling sensor, we analyzed the distribution of the attractant chemokine Sdf1 during migration of the zebrafish posterior lateral line primordium, a cohort of abou...

Obesity is recognized as a low-grade chronic inflammatory state which involves a chemokine network contributing to a variety of diseases. As a first step toward understanding the roles of the obesity-driven chemokine network, we used a 3T3-L1 cell differentiation model to identify the chemokine profiles elicited during adipogenesis and how this profile is modified by epidermal growth factor (EG...
