Sound waves transform stem cells into bone tissue

Researchers from the Melbourne Royal Institute of Technology have developed a method of accelerated bone tissue growth for damage regeneration. As a basis, they took a well-known material – stem cells, but subjected them to non-standard effects. Unlike previous experiments, Australian scientists switched from processing samples with low-frequency radiation to high-frequency radiation — and this gave good results.

We are talking about mesenchymal stem cells, which can be extracted not only from the bone marrow, but also from adipose tissues, and this is a more gentle procedure for the body. They easily turn into bone tissue, but the process is extremely slow. To stimulate it, scientists subjected them to vibrations in the megahertz range.

Experimentally, it was found that the optimal effect is achieved at a frequency of 10 MHz for 10 minutes a day. By the fifth day, markers appeared that indicate the beginning of the formation of bone tissue. Now it remains to transplant the cells to the injury site or to the implant so that the tissue begins to grow and strengthen. The researchers noted that scaling the process is incredibly simple, the entire technical part of the work is extremely cheap, which opens up new horizons in tissue bioengineering.
