Researchers from RMIT University have shown in a new study that stem cells treated with high-frequency sound-waves turned into bone cells, both quickly and efficiently.
This incredible discovery could offer an incredible solution for challenges currently faced in the field, for example some experimental processes to change adult stem cells into bone cells use expensive equipment, therefore making mass production difficult.
“We can use the sound waves to apply just the right amount of pressure in the right places to the stem cells, to trigger the change process.” Co-lead researcher Distinguished Professor Leslie Yeo said.
However, using high-frequency sound waves from the new sound-wave generating device they created, RMIT researchers have managed to overcome these setbacks, with their findings showing that the treatment was effective on multiple types of cells, including fat-derived stem cells. These type of cells are far less painful to extract from a patient. The device can also be used to precisely manipulate cells, fluids and materials.
Even better, the new method is considerably cheaper compared to other experimental methods previously used, thanks to the low-cost microchip device that is used for the stem cell treatment. The use of the sound waves also cuts treatment time by several days, according to Gelmi, a Vice-Chancellor’s Research Fellow at RMIT.
