What are marine elasmobranchs?
Marine elasmobranchs are a group of fish that includes sharks and rays, known for their cartilaginous skeletons.
Why is gene expression important in developmental biology?
Gene expression is crucial for understanding how cells differentiate and develop into specific tissues and organs during embryonic development.
How does this study benefit biomedical research?
By using marine elasmobranchs as model organisms, researchers can gain insights into developmental processes that may be relevant to human health and disease.
What techniques are used in this study?
The study employs RNA whole mount in situ hybridization and histological techniques to visualize gene expression.
What are goblet cells?
Goblet cells are specialized epithelial cells that produce mucus, playing a key role in protecting and lubricating surfaces in the body.
Can this protocol be applied to other species?
While this protocol is specifically adapted for marine elasmobranchs, similar techniques may be modified for use in other species.
