Journey into the Heart of the Wild
Step inside the science of nature. The Stem Cell Zoo offers a unique look at how animal life begins, grows, and adapts—unlocking clues that could preserve endangered species and transform animal care.
Our Vision

We strive to decode nature’s blueprint using stem cell science to better understand, protect, and preserve life across species.

Our Mission

Through advanced stem cell research and collaboration, we offer new ways to explore development, regenerate life, and conserve endangered species.

Our Motto

Educating and empowering future generations through science, compassion, and hands-on discovery.

Explore the Science Behind the Zoo

Learn how stem cells power conservation, discovery, and your role in the future of animal care.

What are stem cells

First, a little biology happens. An egg cell carries one half of the genes from a female and a sperm cell does the same for the male. After an egg cell is successfully fertilized by a sperm cell, an individual is formed with a unique and complete set of genes.

Stem cell repository

The stem cells isolated from our animal patients can be stored at liquid nitrogen temperatures for an indefinite period of time. They can be thawed and placed on tissue culture media to expand their population.

How can you help?

Your tax-deductible donations to The Stem Cell Zoo will be used to pay for the isolation of stem cells from adipose tissue collected from zoo animals as part of their regularly scheduled preventive medicine program.

Caring for Wildlife, Guided by Science
At The Stem Cell Zoo, animal care is rooted in compassion and cutting-edge science. From daily health routines to innovative stem cell therapies, our team is committed to the long-term wellbeing of every species we serve.
