Scientists at Texas A&M University say they may have found a way to stop or even reverse the decline of cellular energy production.<\/p>\n
Their approach uses engineered particles to push stem cells into producing extra mitochondria, which then move into weakened cells and restore lost energy.<\/p>\n
The work could influence treatments for aging, heart disease, and neurodegenerative disorders.<\/p>\n
Researchers linked many age-related and degenerative conditions to declining mitochondria.<\/p>\n
As cells grow older or suffer chemical or disease-induced injury, they lose the tiny structures that power their functions. Once that decline accelerates, cell health drops sharply.<\/p>\n
The team tested a method to counter that loss. They created microscopic flower-like particles, or nanoflowers, made of molybdenum disulfide.<\/p>\n
When stem cells encountered these particles, they produced roughly twice their usual number of mitochondria. These boosted stem cells then transferred the surplus to impaired cells.<\/p>\n
Dr. Akhilesh K. Gaharwar, a professor of biomedical engineering, said the approach trains healthy cells to support weaker ones. \u201cWe have trained healthy cells to share their spare batteries with weaker ones,\u201d he said.<\/p>\n
He added that increasing mitochondria inside donor cells helps damaged cells regain function without the need for drugs or genetic changes.<\/p>\n
Boosted cells show strong recovery<\/p>\n
The upgraded stem cells transferred two to four times more mitochondria than untreated ones.<\/p>\n
Damaged cells absorbed these mitochondria and regained energy output. They also showed improved resistance to stress.<\/p>\n
Exposed cells survived chemotherapy-like insults that normally cause a rapid decline.<\/p>\n
Lead author John Soukar compared the effect to swapping out a failing power source.<\/p>\n
\u201cIt\u2019s like giving an old electronic a new battery pack,\u201d he said. <\/p>\n
He explained that instead of discarding weakened cells, the method lets researchers \u201cplug\u201d charged mitochondria from strong cells into struggling ones.<\/p>\n
Existing methods to increase mitochondria rely on small-molecule drugs that clear quickly from cells. <\/p>\n
The Texas A&M<\/a> technique uses larger nanoparticles that stay inside stem cells longer and continue to trigger mitochondrial production.<\/p>\n Soukar said early data suggests possible monthly dosing rather than frequent treatments.<\/p>\n Gaharwar called the work an early but promising step. \u201cThis is an early but exciting step toward recharging aging tissues<\/a> using their own biological machinery,\u201d he said.<\/p>\n He noted that safely boosting this natural sharing system could help slow or even reverse some aging effects.<\/p>\n Broad therapeutic potential<\/p>\n Researchers say the method could work across many tissues. Stem cells<\/a> already play a central role in regenerative medicine. <\/p>\n Enhancing them with nanoflowers could expand their capabilities.<\/p>\n Soukar said the approach offers flexibility. \u201cYou could put the cells anywhere in the patient,\u201d he said.<\/p>\n
