Insights
Ferrets offer a promising new animal model for studying neonatal brain disease. Their developing brains share similarities with human infants, aiding research into perinatal brain injury and neurodevelopmental outcomes.
Area of Science:
- Neuroscience
- Developmental Biology
- Comparative Medicine
Background:
- Complications of prematurity can impair infant brain development, leading to poor neurodevelopmental outcomes.
- Current small animal models have limitations in translating findings to human neonates.
- Large animal models are expensive and have limited developmental testing capabilities.
Purpose of the Study:
- To evaluate the ferret as a novel intermediate animal model for neonatal brain disease.
- To assess the suitability of ferret brain development for modeling perinatal brain injury.
- To explore the potential of ferrets in neonatal neurodevelopmental research.
Main Methods:
- Review of ferret brain growth and developmental characteristics.
- Comparison of ferret brain development to human and other animal models.
- Assessment of ferret attributes for modeling perinatal brain injury.
Main Results:
- Ferrets are born with lissencephalic brains that develop into complex gyrencephalic structures postnatally.
- Their brain development shares similarities with human infants, offering a more relevant model.
- Ferrets represent a small animal with a gyrified, altricial brain suitable for neonatal studies.
Conclusions:
- Ferrets possess unique characteristics that make them an appealing model for neonatal brain disease research.
- This species has significant potential for advancing our understanding of perinatal brain injury.
- Ferrets may bridge the gap between small and large animal models in neurodevelopmental studies.
Abstract:
Complications of prematurity often disrupt normal brain development and/or cause direct damage to the developing brain, resulting in poor neurodevelopmental outcomes. Physiologically relevant animal models of perinatal brain injury can advance our understanding of these influences and thereby provide opportunities to develop therapies and improve long-term outcomes. While there are advantages to currently available small animal models, there are also significant drawbacks that have limited translation of research findings to humans. Large animal models such as newborn pig, sheep and nonhuman primates have complex brain development more similar to humans, but these animals are expensive, and developmental testing of sheep and piglets is limited. Ferrets (Mustela putorius furo) are born lissencephalic and undergo postnatal cortical folding to form complex gyrencephalic brains. This review examines whether ferrets might provide a novel intermediate animal model of neonatal brain disease that has the benefit of a gyrified, altricial brain in a small animal. It summarizes attributes of ferret brain growth and development that make it an appealing animal in which to model perinatal brain injury. We postulate that because of their innate characteristics, ferrets have great potential in neonatal neurodevelopmental studies.
