Colorado State University received a $20 million donation that will help the school build a regenerative-medicine research facility.

The donation, from an anonymous racehorse breeder, fulfills a $65 million matching challenge from the project’s leading donors.

The $20 million donation falls in step with CSU’s public announcement in February to begin its first $1 billion campaign effort to raise support for teaching, research, outreach and veterinary clinical services.

In December 2014, local billionaire and Liberty Media’s chairman John Malone and his wife, Leslie, made the largest cash gift in CSU history — $42.5 million — for the facility.

The CSU Institute for Biologic Translational Therapies will research the body’s healing powers.
