Area of Science:

Ophthalmology
Developmental Biology
Animal Models

Background:

The pig eye is anatomically and physiologically similar to the human eye.
This makes it a valuable animal model for studying retinal diseases.

Purpose of the Study:

To characterize retinal histology in developing and mature pig retinas.
To use antibodies for well-established retinal cell markers, commonly used in rodents.

Main Methods:

Eyes were collected from fetal, 1-week-old, and 6-month-old pigs.
Immunohistochemistry was performed using a panel of retinal markers.
Mouse retina at postnatal day 5 served as a reference for histogenesis comparison.

Main Results:

Most markers showed similar distribution in pig and mouse retinas.
Pig retinas displayed unique characteristics, such as calbindin-immunoreactive cones and Islet1-positive horizontal cells.
Photoreceptor segment length increased with age in pigs.

Conclusions:

Pig and human retinal development show similar marker distribution and histogenesis.
The pig is a valuable model for retinal disease and repair studies.
This study validates antibodies for pig retinal cell phenotyping.
