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.

Hair Cells

Hair cells are the sensory receptors of the auditory system—they transduce mechanical sound waves into electrical energy that the nervous system can understand. Hair cells are located in the organ of Corti within the cochlea of the inner ear, between the basilar and tectorial membranes. The actual sensory receptors are called inner hair cells. The outer hair cells serve other functions, such as sound amplification in the cochlea, and are not discussed in detail here. Hair cells are named after...

An Introduction to Aging and Regeneration

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...
FAQs
Phase transitions are regulated by signals exchanged among follicular stem cells, dermal papilla cells, and surrounding tissues. These interactions help coordinate when follicles enter growth, regression, or resting states, making the timing of each phase a central readout in a Hair Regeneration Model. Researchers can therefore connect altered signaling with changes in follicle activity rather than examining hair production as an isolated outcome.
Follicular stem cells and dermal papilla cells contribute different perspectives on regeneration. Stem cells are examined for their behavior during tissue renewal, while dermal papilla cells are considered part of the signaling environment that influences follicle activity. Including surrounding tissues adds another biological context, allowing studies to evaluate how local cellular interactions shape cycling and repair.
Because follicle activity links developmental biology with tissue renewal, the model provides a tractable setting for examining regenerative processes in mammalian tissues. It lets researchers study stem cell behavior within a recognizable cycle of growth, regression, and rest, while also considering repair-related interactions among cells and their surrounding tissue. This combination supports mechanistic biology beyond hair production alone.
Studies can focus on the follicle’s changing state and on the cellular interactions associated with that change. Researchers examine growth, regression, and resting phases, then relate those observations to follicular stem cells, dermal papilla cells, and surrounding tissues. This approach produces information about both cycle regulation and tissue renewal, even when the research question concerns broader mammalian biology.
Researchers can use Hair Regeneration Models to evaluate how genetic or environmental factors affect follicle activity. The model provides an experimental biological context for comparing changes in cycling or regenerative behavior with the factor being investigated. Such comparisons help connect a potential influence to developmental pathways and tissue responses, creating a basis for more focused studies of follicle regulation.
Potential treatments for hair loss and skin disorders can be examined by observing how follicular activity and regenerative behavior respond within the model. Its relevance extends beyond treatment testing: the same system supports analysis of developmental pathways, stem cell behavior, and tissue repair. These applications make it useful for linking biological mechanisms to disease-related or therapeutic questions.
