Embryonic stages are the most susceptible to xenobiotics. Although chemical toxicity depends on salinity, no method exists to test the salinity dependence of toxicity to aquatic organisms. Here, we describe a new and high-throughput method for determining the salinity dependence of toxicity to aquatic embryos.

An Introduction to Aging and Regeneration
0 Views •
2023
Tissues are maintained through a balance of cellular aging and regeneration. Aging refers to the gradual loss of cellular function, and regeneration is the repair of damaged tissue generally mediated by preexisting adult or somatic stem cells. Scientists are interested in understanding the biological mechanisms behind these two complex processes. By doing so, researchers may be able to use somatic stem cells to treat degenerative diseases and develop therapies that could delay the effects of...

In newt, the lens regenerates always from the dorsal iris by transdifferentiation of the iris pigmented epithelial cells (IPEs). Here we describe a procedure to culture dorsal and ventral newt IPE cells and their implantation to the newt eye. The implanted cells are then studied by tissue sectioning and immunohistochemistry.

Because many zebrafish models of neurological and non-neurological diseases are studied in the adult fish rather than the embryo/larvae, we developed a quantitative lateral line regenerative assay that can be applied to adult zebrafish disease models. The assay involved resolution at the 1) neuromast and 2) individual hair cell levels.
FAQs
The wound epidermis forms rapidly after injury and provides a specialized surface at the damaged site. Its formation marks an early transition from wound closure toward organized tissue rebuilding. Studying this structure helps researchers examine how the initial injury response creates conditions in which progenitor cells and surrounding tissues can participate in regeneration.
Progenitor cells contribute to rebuilding by responding alongside nearby tissues rather than acting independently. Their coordinated proliferation, migration, and differentiation help generate replacement structures, while surrounding cells provide local signals and organizational context. This interaction allows regeneration to connect cellular behavior with the restoration of tissue form and function.
Medaka provides a vertebrate model in which researchers can examine how injury responses, cell behaviors, and molecular signals support tissue restoration. Comparing these processes with regeneration in other vertebrates can clarify why some organisms replace damaged structures more effectively than others, revealing conserved principles as well as differences in repair capacity.
Studies can track how cells proliferate, migrate, and differentiate after injury, while also examining the formation of the wound epidermis. These observations show how local cellular responses contribute to rebuilding missing structures. Together, they provide a way to connect visible tissue restoration with the underlying sequence of cellular events.
Within developmental biology, researchers use medaka to study how molecular signals and cellular behaviors organize tissue repair after injury. The central focus is the relationship between regeneration and developmental patterning, meaning the processes that establish structure and form. This approach links repair mechanisms with principles that guide normal tissue development.
Medaka regeneration studies can address how organisms restore both tissue structure and function, how injury responses become coordinated rebuilding programs, and why regenerative ability varies among vertebrates. The findings may also inform research on improving healing and regeneration in other organisms, while preserving a focus on the cellular and molecular basis of these processes.
