Texas A&M Researchers Use Nanoflowers to Revitalize Aging Cells

Biomedical researchers at Texas A&M University have developed a groundbreaking method that utilizes microscopic particles known as nanoflowers to enhance the energy production of stem cells. Published on November 27, 2025, this innovative approach enables stem cells to generate approximately double the usual number of mitochondria. These energized stem cells subsequently transfer their surplus mitochondria to weakened cells, potentially reversing energy loss associated with aging and degenerative diseases.

The research, led by Dr. Akhilesh K. Gaharwar and Ph.D. student John Soukar from the Department of Biomedical Engineering, presents a promising advance in regenerative medicine. Mitochondrial decline is linked to aging, heart disease, and various neurodegenerative conditions, including Alzheimer’s disease. By addressing the diminishing number of mitochondria, the team aims to restore energy production in damaged cells, thereby improving their overall health and functionality.

Nanoflowers Enhance Stem Cell Functionality

The technique involves combining stem cells with nanoflowers, which are made from molybdenum disulfide, an inorganic compound capable of forming diverse two-dimensional structures. Upon exposure to these nanoflowers, the stem cells significantly increased their mitochondria production, yielding two to four times more mitochondria than untreated cells. When these enhanced stem cells were placed next to damaged or aging cells, they successfully transferred their excess mitochondria, revitalizing the energy production of neighboring cells.

“We have trained healthy cells to share their spare batteries with weaker ones,” said Dr. Gaharwar. He emphasized that this method does not involve genetic modification or drug administration, representing a significant advancement in cellular therapies. The treated cells demonstrated improved energy levels and heightened resistance to apoptosis, even when subjected to harmful treatments like chemotherapy.

Soukar, the lead author of the study, likened this process to rejuvenating an old electronic device with a new battery pack. “Instead of tossing them out, we are plugging fully charged batteries from healthy cells into diseased ones,” he remarked.

A Sustainable Approach to Mitochondrial Therapy

Traditional methods to boost mitochondrial numbers often require frequent interventions due to their short-lived effects. Drug-based therapies typically involve small molecules that exit cells rapidly, necessitating regular treatments for sustained benefits. In contrast, the larger nanoflowers remain inside the cells, continuously stimulating mitochondrial production. This could allow therapies based on this technology to be administered approximately once a month, significantly enhancing treatment compliance.

“This is an early but exciting step toward recharging aging tissues using their own biological machinery,” Dr. Gaharwar stated. He expressed hope that by safely enhancing this natural power-sharing system, it could eventually aid in mitigating or reversing some cellular aging effects.

The project received funding from prominent institutions, including the National Institutes of Health, the Welch Foundation, the Department of Defense, and the Cancer Prevention and Research Institute of Texas. Additional support was provided by the President’s Excellence Fund at Texas A&M University and the Texas A&M Health Science Center Seedling Grant.

Researchers believe that the flexibility of this technique could allow for applications across various tissues in the body. “You could put the cells anywhere in the patient,” noted Soukar. “For cardiomyopathy, you can treat cardiac cells directly, and for muscular dystrophy, you can inject them right into the muscle.” This versatility opens up numerous possibilities for future treatments.

As the field of regenerative medicine evolves, the application of nanoflowers to enhance stem cell performance could represent a pivotal advancement. With ongoing research and potential clinical trials, this discovery may reshape the landscape of treatments for aging and degenerative diseases.
