The rodent retina has long been recognized as an accessible window to the brain. In this technical paper we provide a protocol that employs the mouse model of oxygen-induced retinopathy to study the mechanisms that lead to failure of vascular regeneration within the central nervous system after ischemic injury. The described system can also be harnessed to explore strategies to promote regrowth of functional blood vessels within the retina and CNS.

This video presents electrophysiological recordings from organotypic co-cultures of spinal cord slices, captured using a multi-electrode array or MEA device. These recordings assess neuronal regeneration between the slices. The synchronized electrical activity observed confirms successful neural regeneration.

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...

A System for Culturing Iris Pigment Epithelial Cells to Study Lens Regeneration in Newt

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.
FAQs
Assessment becomes informative when structural restoration and functional recovery are examined together. A tissue may regain visible organization without recovering its original performance, or it may show partial function despite incomplete regrowth. Recording both dimensions helps investigators distinguish complete regeneration from incomplete repair and from scarring, rather than treating appearance alone as evidence of successful recovery.
The outcome can reflect the behavior of resident cells or broader cell populations, as well as the signals and environmental conditions surrounding injury. Regeneration assessment is useful because it links the observed recovery pattern to these possible influences. Comparing outcomes under different biological conditions can reveal which cellular, signaling, or environmental factors are associated with more effective restoration.
Regeneration assessment can be applied at developmental, cellular, and organismal scales, but the question changes with the scale. At the cellular level, investigators may focus on population recovery; at the tissue or organismal level, they can evaluate restored organization and function. Using the appropriate scale prevents a local cellular response from being mistaken for full biological recovery.
A typical workflow starts by establishing the extent of injury, then follows regrowth over time and evaluates structural organization alongside functional return. Researchers compare these observations with the starting injury and with other recovery outcomes when appropriate. This sequence creates a consistent basis for judging whether the response represents restoration, incomplete repair, or scarring.
In disease-mechanism studies, the assessment provides a way to connect an abnormal recovery pattern with the biology of tissue restoration. By documenting how structure and function change after damage, investigators can compare healthy and disease-related outcomes. This makes the approach relevant for identifying recovery failures and for evaluating strategies intended to improve tissue restoration.
Results should be interpreted as a recovery profile rather than a single measurement. The extent of injury establishes the context, regrowth over time shows progression, and structural and functional observations indicate the quality of the outcome. Together, these measures can reveal whether recovery is complete, partial, or replaced by scarring, supporting comparisons among experimental conditions.
