Invertebrate models for biomedical research, testing, and education.

Area of Science:

• Zoology
• Biomedical Research
• Pharmacology

Background:

• Invertebrates have a long history of medicinal use and as research models.
• Growing concerns about vertebrate animal use drive interest in invertebrate alternatives.
• Invertebrate models are increasingly recognized for their utility in studying diseases and biological processes.

Purpose of the Study:

• To review the diverse applications of invertebrate models in scientific research and education.
• To highlight key invertebrate species used in various biological systems and disease studies.
• To discuss bioactive products derived from invertebrates and their potential applications.

Main Methods:

• Categorization of invertebrate models by biological system, process, or disease.
• Review of established and emerging invertebrate model organisms.
• Examination of bioactive compounds discovered from invertebrate sources.

Main Results:

• Invertebrates like Drosophila melanogaster and Caenorhabditis elegans are prominent research models.
• Invertebrate models have contributed to discoveries across developmental biology, aging, and disease research.
• Numerous bioactive products have been identified from invertebrates, with therapeutic potential.

Conclusions:

• Invertebrate models provide essential alternatives to vertebrate animals in research and teaching.
• Their application spans fundamental biology to translational medicine.
• This review serves as a reference for scientists and animal care committees seeking ethical research models.
