The phenomenon of "tissue regeneration" has attracted numerous biologists for many years. Regenerative capacity differs greatly across species. The lower vertebrates such as zebrafish have exceptionally high regeneration abilities, while most high vertebrate species including humans do not have a remarkable ability for regeneration. It has been found zebrafish has a strong ability to regenerate a variety of tissues and organs including fins, heart, retina, optic nerve, spinal cord, liver, and sensory hair cells. Thus, we can learn useful information from the zebrafish regeneration model to understand the human regeneration defects and promote the development of regenerative medicine. This review summarizes the current research status for regeneration of heart, nerve, liver, and fin regeneration in zebrafish.

Hypoxia-mediated cardiac tissue injury and its repair or regeneration are one of the major health management challenges globally. Unlike mammals, lower vertebrate species such as zebrafish (Danio rerio) represent a natural model to study cardiac injury, repair and regeneration. Thyroxine (T3) has been hypothesised to be one of the endocrine factors responsible for the evolutionary trade-off for acquiring endothermy and regenerative capability in higher vertebrates.

The cerebellum is a highly conserved brain compartment of vertebrates. Genetic diseases of the human cerebellum often lead to degeneration of the principal neuron, the Purkinje cell, resulting in locomotive deficits and socio-emotional impairments. Due to its relatively simple but highly conserved neuroanatomy and circuitry, these human diseases can be modeled well in vertebrates amenable for genetic manipulation.

The intricate control of collective cell dynamics is crucial for enabling organismic development and tissue regeneration. Despite the availability of various in vitro and in vivo models, studies on tissue-scale cell dynamics and associated emergent properties in living systems remain methodically challenging. Here, we describe key advantages of using the adult zebrafish tailfin (caudal fin) as a robust in vivo model for dissecting millimeter-scale collective cell dynamics during regeneration and wound healing in a complex tissue.

YAP is a central regulator of the Hippo-YAP signaling axis, an evolutionarily conserved pathway that modulates organ growth and regeneration. Dysregulation of YAP signaling leads to uncontrolled proliferation, promoting epithelial-to-mesenchymal transition and invasion in cancer metastasis. Exogenous manipulation of YAP activity at the second-to-minute timescale is an important step in studying the signaling pathway.
