Significant progress has recently been made in our understanding of animal regenerative
biology, spurred on by the use of a wider range of model organisms and an increasing …

Here we discuss the developmental and homeostatic conditions necessary for Hydra
regeneration. Hydra is characterized by populations of adult stem cells paused in the G2 …

The freshwater polyp Hydra is a cnidarian used as a model organism in a number of fields,
including the study of the origin and evolution of developmental mechanisms, aging …

For ages, regeneration has intrigued countless biologists, clinicians, and biomedical
engineers. In recent years, significant progress made in identification and characterization of …

Cnidarian Hydra polyps escape senescence, most likely due to the robust activity of their
three stem cell populations. These stem cells continuously self-renew in the body column …

Hydractinia, a representative marine colonial hydroid, was the first organism in the history of
biology in which migratory precursors of germ cells were described and termed “stem …

The convergence of morphogenesis into viable organisms under variable conditions
suggests closed‐loop dynamics involving multiscale functional feedback. We develop the …

The silencing of genes whose expression is restricted to specific cell types and/or specific
regeneration stages opens avenues to decipher the molecular control of the cellular …

Hydra is one of the simplest metazoans and thus an important model organism for studies
on the evolution of developmental mechanisms in multi-cellular animals. In Hydra apoptosis …

Hydra has been well known for over 200 years for its remarkable regenerative capacity. In
addition to small pieces excised from the body, reaggregates of dissociated single cells can …
