Scientists Find New Way To Rejuvenate Ageing Human Cells

Researchers have unveiled a promising technique that revives ageing human cells by enhancing mitochondrial activity, offering a potential pathway to treat degenerative and age-related diseases. The breakthrough centres on improving the energy-producing ability of cells that naturally weaken over time.

Focus on Mitochondria and Ageing

The study by Texas A&M University highlights how mitochondria, the cell’s energy generators, decline in efficiency with age, contributing to heart, brain and metabolic disorders. Restoring mitochondrial function has long been considered key to slowing biological ageing at the cellular level.

Nanoflower Technology Boosts Cellular Energy

Scientists developed microscopic “nanoflowers” from molybdenum disulfide. These particles, shaped like tiny blossoms, contain pores that absorb harmful reactive oxygen species. By reducing oxidative stress, the nanoflowers activate genes that trigger the formation of new mitochondria in human stem cells, significantly improving their vitality.

Healthier Cells Revive Weaker Neighbours

The energised stem cells can transfer healthy mitochondria to nearby damaged cells, effectively restoring their activity. Researchers describe this as akin to replacing depleted batteries rather than merely recharging them. The method does not require drugs or genetic modification and could serve as a foundation for safe regenerative therapies.

Exam Oriented Facts

• Mitochondria are energy-producing structures whose decline accelerates ageing.
• Nanoflowers are made from molybdenum disulfide with sponge-like pores.
• The technique increases mitochondrial transfer between stem cells and damaged cells.
• Lab tests showed enhanced muscle cell growth and improved survival in damaged heart cells.

Potential for Future Therapeutic Use

The technique nearly doubled the natural transfer of mitochondria between cells, with smooth muscle cells showing three- to fourfold growth improvements. Heart cells injured by chemotherapy also recorded higher survival rates. Scientists believe the approach could be adapted to support cardiovascular repair, treat muscular dystrophy and rejuvenate tissues across the body, marking the beginning of broader regenerative possibilities.
