A team of scientists from the University of Kyoto followed up on their previous study of 2018 and decided to review, How sound waves affect cell behavior. And showed that Individual cells perceive sound. It is a mechanical wave that spreads faster the denser the environment. On the contrary, it does not arise at all in a vacuum.
“In order to examine the effects of sound on cellular activity, we have designed a system that allows you to expose cultivated cells to sound waves,” said the head of the study by Masahiro Kumeta. Scientists attached a vibrating converter inverted to the ceiling of the laboratory shelf. He attached to the amplifier and digital player to They sent sound signals through the membrane directly to the cell culture container. Thus, they could simulate the acoustic pressure corresponding to the natural range of the sound that usually arises in the body.
Using RNA-sequencies and microscopy techniques, they examined how the cells respond to the sound. And the results were surprising: Cells respond to sound stimuli in a commonly audible range. The sound on the process of differentiation of fat cells – the conversion into mature fat cells – had a particularly pronounced effect. It has been shown that the sound can suppress this transformation. This opens the possibility of using acoustic stimulation to affect the condition of cells and tissues.
“Sound is immaterial, and therefore acoustic stimulation is non -invasive, safe and immediate. It has great potential for medicine and health care,” supplies the kumet. Extra scientists identified approximately 190 sounds sensitive genes, detected the effect of sound on cell adhesion And they also described the mechanism by which acoustic signals spread inside the cell.
