The Turing, or reaction-diffusion (RD), model is one of the best-known theoretical models
used to explain self-regulated pattern formation in the develo** animal embryo. Although …

The processes of bone growth, modeling, and remodeling determine the structure, mass,
and biomechanical properties of the skeleton. Dysregulated bone resorption or bone …

INTRODUCTION The cnidarian polyp Hydra undergoes continual self-renewal and is
capable of whole-body regeneration from a small piece of tissue. The stem cell populations …

Animals are colonized by coevolved bacterial communities, which contribute to the host's
health. This commensal microbiota is often highly specific to its host-species, inferring strong …

Wnt genes are important regulators of embryogenesis and cell differentiation in vertebrates
and insects. New data revealed by comparative genomics have now shown that members of …

Wnt genes and β-Catenin signaling are involved in axial patterning processes in vertebrate
embryogenesis in setting up the Spemann–Mangold organizer in amphibian embryos. An …

The freshwater polyp Hydra provides a potent model system for investigating the conditions
that promote wound healing, reactivation of a developmental process and, ultimately …

Regeneration is widespread throughout the animal kingdom, but our molecular
understanding of this process in adult animals remains poorly understood. Wnt/β-catenin …

Because research on regeneration has a long history, some classic definitions and concepts
about regeneration which were established in earlier times have been retained without …

The basis for Hydra's enormous regeneration capacity is the “stem cellness” of its epithelium
which continuously undergoes self-renewing mitotic divisions and also has the option to …
