One of the most fascinating questions in regenerative biology is why some animals can
regenerate injured structures while others cannot. Skeletal muscle has a remarkable …

Mef2 is a conserved and significant transcription factor in the control of muscle gene
expression. In cell culture Mef2 synergises with MyoD-family members in the activation of …

How does neural activity drive muscles to produce behavior? The recent development of
genetic lines in Hydra that allow complete calcium imaging of both neuronal and muscle …

We present an organism-wide, transcriptomic cell atlas of the hydrozoan medusa Clytia
hemisphaerica and describe how its component cell types respond to perturbation. Using …

Animals are typically composed of hundreds of different cell types, yet mechanisms
underlying the emergence of new cell types remain unclear. Here we address the origin and …

Muscle-based movement is a hallmark of animal biology, but the evolutionary origins of
myocytes are unknown. Although believed to lack muscles, sponges (Porifera) are capable …

Across the animal kingdom, environmental light cues are widely involved in regulating
gamete release, but the molecular and cellular bases of the photoresponsive mechanisms …

The capacity to regenerate lost or injured body parts is a widespread feature within
metazoans and has intrigued scientists for centuries. One of the most extreme types of …

Fishery, market and consumption of edible jellyfish are currently limited in western countries
by the lack of market demand for jellyfish products and the absence of processing …

Homeostasis constitutes a key concept in physiology and refers to self‐regulating processes
that maintain internal stability when adjusting to changing external conditions. It diminishes …
