Fig. 1From: ERK signaling waves via body-wall muscles guide planarian whole-body regeneration across long distancesThree models on ERK signaling waves in different kinds of tissues. A Schematic of two-type ERK activity propagation patterns in the epidermis (Hiratsuka et al. 2015). B Schematic of ERK activity waves that travel across regenerating scales (De Simone et al. 2021). C Ultra-fast ERK waves during planarian whole-body regeneration (Fan et al. 2023). D Schematic of ERK activity propagation between long cells during planarian regeneration (Fan et al. 2023)Back to article page
