Supporting the shift to animal component-free and xeno-free research in cell culture

PromoCell: The pharmaceutical and biotechnology industries are shifting toward more ethical, consistent, and regulatory-compliant drug discovery and translational research.


This shift is particularly evident in cell culture. Researchers increasingly demand animal-free alternatives that deliver superior reproducibility and meet stringent regulatory requirements. Drug discovery and cell therapy applications now utilize animal component-free (ACF) and xeno-free (XF) cell culture media for GMP-grade product development.

What are ACF and XF media, and why are they important?

Animal component-free media are formulations that are free of components derived from animal or human sources. These include serum, proteins, and other biological materials that are commonly used in cell culture.

Xeno-free media are formulated without any components from non-human animal sources. The use of XF media ensures that human cell cultures are maintained in completely human-compatible environments.

ACF and XF media ensure batch-to-batch consistency and eliminate unknown biological contaminants. They also address regulatory compliance issues that can compromise research outcomes and therapeutic development timelines. Stricter regulatory guidelines make the adoption of ACF and XF media essential, not just ethical.

Advantages of using ACF and XF media formulations

The transition from conventional cell culture media to ACF and XF formulations has several scientific and ethical advantages that can affect research quality and regulatory acceptance. ACF and XF formulations provide batch-to-batch consistency, as they eliminate the variability introduced by animal-derived components and unknown proteins that can influence experimental data and cell behavior.

In addition, the use of ACF and XF media can enhance reproducibility across different laboratories. Regulatory agencies require detailed documentation of all culture components and their origins. Therefore, switching to ACF and XF formulations is particularly important when developing cell-based therapies.

The use of ACF and XF media also has ethical advantages. Organizations such as People for the Ethical Treatment of Animals (PETA) and the National Centre for the Replacement, Refinement and Reduction of Animals in Research (NC3Rs) continuously update their resources regarding ACF products and advocate for animal-free research. These formulations eliminate animal-derived materials, supporting animal welfare policies and reducing the environmental impact of traditional serum production.
