Lab-Grown Donkey Collagen Could Save Species from Extinction

Scientists in Brazil are racing to save donkeys from extinction with a revolutionary solution that could change traditional medicine forever.

Researchers at the Federal University of Parana are developing lab-grown donkey collagen to replace ejiao, a traditional Chinese medicine made from donkey skins. The anti-aging tonic has become so popular among China's growing middle class that donkey populations worldwide are plummeting at alarming rates.

Professor Carla Molento leads the project at the university's Cellular Animal Science Laboratory. Her team is building a system that can produce donkey hide gelatin at scale without harming a single animal.

The lab-grown version carries the same DNA as natural donkey collagen, meaning it retains all the traditional properties people seek. But it comes with major advantages: no heavy metals, no disease risks, and zero contamination from pathogens that sometimes appear in conventional products.

China's economic boom transformed ejiao from a luxury item into a mainstream product millions can afford. That surge in demand created an unsustainable crisis for donkey populations across continents.

The Brazilian team's innovation tackles two problems at once. Donkeys get protection from industrial-scale harvesting, while consumers get a safer, purer product that matches what traditional medicine practitioners recommend.

Why This Inspires

This project shows how modern science can honor cultural traditions while protecting vulnerable species. Rather than asking people to abandon practices passed down through generations, researchers found a way to preserve both heritage and animal welfare.

The work represents a growing trend of scientists using cellular agriculture to solve conservation challenges. When demand threatens a species, creating ethical alternatives becomes an act of hope.

One breakthrough in a Brazilian laboratory might secure the future for donkeys worldwide while respecting the cultural practices that made them valuable.
