Fig. 4.

Improved myofibrillar organization and maintained Ca²⁺ cycling of syncytial aGPVM cultures exposed to electrical stimulatory cue. Format identical to that in Fig. 1. A, B: Enhanced myofibrillar organization, most obviously apparent from larger and more distinct peak in B at f_y ~ 0.5 μm⁻¹ (black relation, averaged from n = 17 monolayers). For reference, gray relation is control histogram of culture without stimulatory cue, reproduced from Fig. 1B. C: Unchanged global Ca²⁺ cycling.
