In vivo phenotype of animals exposed to hypergravity and/or vibration four days after the exposure. Animals in all groups were able to regenerate the head (the eyes are indicated with arrow heads). No alterations are observed between the animals from the four different conditions. n ≥ 10. Scale bar = 1 mm.
