Key Takeaways
  • • The Marcus Foundation donated $28.7 million to USC's Stem Cell Center to fund clinical trials for stem-cell-based therapies designed to regenerate cardiac tissue following heart attacks, representing the largest gift the foundation has given to USC and one of its largest donations to academic medicine overall.
  • • The donation will support Dr. Chuck Murry's research team in advancing gene-edited cellular therapy, which the foundation's chief science officer characterized as having reached a critical inflection point for clinical application as "living medicine."
  • • Bernie Marcus, Home Depot's billionaire cofounder, died in November 2024 at age 95 with an estimated net worth of $11 billion; his philanthropic legacy continues through the Marcus Foundation, established in 1989 with his wife Billi.
  • • The Marcus Foundation has demonstrated sustained commitment to medical research, having donated $25.9 million for stroke research at Emory University in 2024 and $20 million to establish an integrative medicine department at Jefferson's Sidney Kimmel Medical College in 2019.
Summary
The Marcus Foundation has committed $28.7 million toward stem cell research focused on treating heart attack damage, marking a significant expansion of the foundation's medical research portfolio. The funds will support Dr. Chuck Murry's team at the University of Southern California's Stem Cell Center as they advance clinical trials of stem-cell-based therapies intended to regenerate tissue damaged during cardiac events. According to Jonathan Simons, the Marcus Foundation's chief science officer, the donation reflects confidence that gene-edited cellular therapy has matured sufficiently to warrant investment in clinical applications as "living medicine."

The gift represents the largest contribution the Marcus Foundation has directed to USC and ranks among its most substantial academic medicine donations to date. This latest commitment underscores the foundation's strategic focus on advancing regenerative and precision medicine approaches. The foundation's medical research trajectory includes a $25.9 million donation in 2024 to support stroke research initiatives at Emory University School of Medicine and Grady Health System's Marcus Stroke and Neuroscience Center, as well as a $20 million gift in 2019 to establish the Department of Integrative Medicine and Nutritional Sciences at Jefferson's Sidney Kimmel Medical College.

Bernie Marcus, who cofounded Home Depot in 1978 following his dismissal from Handy Dan, maintained a lifelong interest in medical advancement despite initially pursuing pharmacy rather than medicine due to family financial constraints. Marcus passed away in November 2024 at age 95, leaving behind an estimated net worth of $11 billion. The Marcus Foundation, established in 1989 with his wife Billi, continues to channel Marcus's philanthropic vision toward transformative medical research that aligns with his original professional aspirations.
