For the first time, scientists in China have used a super microscope to watch what happens inside living cells when acupuncture needles are inserted. The images show that the ancient practice can calm what researchers describe as cellular chaos.
The team at the University of Science and Technology of China in Hefei developed a special microscope to observe the process. They inserted acupuncture needles into the bodies of living mice and recorded the cellular response in real time.
What the microscope caught inside living cells
The microscope revealed that acupuncture triggers a chain reaction inside cells. When a needle is inserted and twisted, it causes a brief burst of calcium ions inside the cells near the site. That burst then spreads to neighboring cells, creating a wave of chemical signals.
This wave appears to calm down overactive cells. The researchers observed that cells in a state of stress or inflammation returned to a more stable condition after the acupuncture stimulation. The effect was not limited to the area around the needle. The signal traveled through the body along specific pathways.
Why this matters for traditional Chinese medicine
Acupuncture has been used in China for thousands of years, but its biological mechanism has remained unclear. Many scientists have questioned whether it has any real effect beyond placebo. This study provides direct visual evidence that acupuncture produces a measurable physical response at the cellular level.
The researchers focused on the ST36 acupoint, a point on the leg commonly used in acupuncture treatments. They found that stimulating this point produced a stronger and more widespread cellular response than stimulating other areas of the body. This supports the traditional Chinese medicine concept that certain points on the body are connected to specific organs and functions.
How the super microscope works
The microscope used in the study is called a two-photon fluorescence microscope. It can capture images deep inside living tissue without damaging the cells. The researchers genetically modified the mice so that their cells would glow when calcium levels changed. This allowed them to see the calcium waves as they happened.
The study was published in the peer-reviewed journal Nature Communications. The researchers said their work provides a foundation for understanding how acupuncture works at the molecular level.
For people who use acupuncture to treat pain, inflammation, or other conditions, this research offers a scientific explanation for what they experience. It also opens the door for further studies that could lead to more targeted and effective acupuncture treatments. The super microscope has given scientists a new way to watch the body respond to an ancient practice, and the images are changing how they think about both.
