Animal-derived products in science and current alternatives.

Area of Science:

• Life Sciences
• Biotechnology
• Toxicology

Background:

• Over fifty years post-3Rs definition, animal use persists in basic research, including in vivo experiments and animal-derived products.
• Key animal-derived products like fetal bovine serum (FBS), Matrigel™, and antibodies are widely used in cell culture and assays.
• Production of these products raises significant animal welfare and ethical concerns, alongside risks of contamination impacting scientific data quality.

Purpose of the Study:

• To review and present current animal-free alternatives for in vitro research.
• To address the ethical and scientific limitations associated with animal-derived products in basic research.
• To highlight the role of in silico methodologies in reducing animal use.

Main Methods:

• Literature review of existing animal-free alternatives for in vitro research.
• Analysis of ethical considerations and scientific drawbacks of animal-derived products.
• Exploration of in silico approaches for refining research data.

Main Results:

• Identified and cataloged various animal-free products that can replace FBS, Matrigel™, and antibodies.
• Highlighted the potential of in silico methods to minimize the need for in vitro and in vivo experiments.
• Emphasized the scientific and ethical benefits of transitioning to animal-free research models.

Conclusions:

• Animal-free alternatives are increasingly available and viable for in vitro research.
• Adoption of these alternatives can mitigate ethical concerns and improve data reliability.
• Further development and implementation of animal-free methods are crucial for advancing responsible scientific practices.
