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.

This protocol shows how to consistently excise planarian eyes (optic cups) without disturbing surrounding tissues. Using an insulin needle and syringe, either one or both eyes can be ablated to facilitate investigations into the mechanisms regulating eye regeneration, the evolution of visual regeneration, and the neural basis of light-induced behavior.

Laser Ablation of the Zebrafish Pronephros to Study Renal Epithelial Regeneration

Acute kidney injury (AKI) in humans is a common clinical problem caused by damage to the epithelial cells that comprise kidney nephrons, and AKI is associated with high mortality rates of 50-70%1. Following epithelial cell destruction, nephrons have a limited ability to regenerate, though the mechanisms and limitations that guide this phenomenon remain poorly understood. In this video article, we describe our technique for targeted laser ablation of kidney nephron cells in the zebrafish...
FAQs
Neuronal survival determines whether damaged neural circuits retain cells that can contribute to recovery. A regeneration study therefore examines survival alongside later structural and functional changes, rather than treating regrowth alone as evidence of repair. Measuring which neurons remain helps researchers distinguish preservation of existing tissue from restoration through axonal regrowth, remyelination, or replacement of neural cells.
Axonal regrowth can restore connections disrupted by injury, while remyelination repairs the insulating support associated with neural fibers. These processes address different aspects of recovery and may be evaluated separately or together. Examining both helps a study determine whether structural changes involve renewed neural extensions, repaired myelin, or a combination of changes linked to improved function.
Cellular signals and tissue conditions can support or restrict the biological responses required for neural repair. Their influence helps explain why similar injuries may produce different outcomes within the nervous system. By examining these factors, researchers can relate local biological environments to neuronal survival, axonal regrowth, remyelination, or neural-cell replacement observed during recovery.
Regenerative outcomes differ across nervous system regions because the cellular signals and tissue conditions surrounding an injury are not uniform. A regeneration study compares these regional environments with changes in structure and function over time. This approach helps identify why one region may show more evidence of recovery than another and clarifies which conditions may limit repair.
Researchers use experimental models together with imaging or molecular methods to follow neural changes over time. Imaging can document structural alterations, whereas molecular methods can examine biological changes associated with repair. Repeated measurements create a time-based view of recovery, allowing investigators to relate cellular events such as survival or remyelination to later structural and functional outcomes.
A study can measure structural and functional changes as nervous tissue recovers after damage. Structural assessment may address neuronal survival, axonal regrowth, remyelination, or replacement and repair of neural cells. Functional assessment indicates whether those changes correspond to restored activity or performance. Considering both outcome types helps prevent structural improvement from being interpreted as complete recovery.
This approach is especially useful when researchers need to understand recovery after nervous system injury and the reasons neurological outcomes vary. It connects observations of neural cells and tissue structure with functional changes over time. The resulting knowledge can clarify barriers to repair and inform strategies intended to improve neural restoration after damage.
