The people behind the papers – Donald Ready and Henry Chang

Coordinating contractility across tissues is key for maintaining the fidelity of morphogenetic processes. A new paper in Development explains how cytosolic calcium waves in the interommatidial cells, the pigment-secreting cells in the Drosophila eye, lead to remodelling of the retinal floor, by activating contraction of the basal actomyosin stress fibres. We caught up with the authors, Professor Donald Ready and Associate Professor Henry Chang, both from Purdue University, to find out more about this story.
