The paper introduces a mathematical model of Wnt-Dickkopf interactions in Hydra to explain body-axis formation through mutual inhibition, showing it can drive pattern formation across a broad parameter range.

This study uses mathematical models to analyze regulatory feedback mechanisms in adult neurogenesis, finding that neural stem cells predominantly regulate lineage dynamics.

This study shows that Hydra uses two separate patterning loops for body axis and head formation, challenging the previous single-loop model.
