A short YouTube talk (by Joy Kong, MD) describing use of light at different wavelengths to improve stem-cell infusion outcomes. The speaker says cells are pre-activated by light and that, during infusion, organ-directed light both increases cell mobility/proliferation and activates adhesion molecules in target organs, which helps those organs "trap" the infused stem cells.
Light of cells actually is a good combo. Light in different frequencies, different wavelengths can really help target different tissues. So when we are giving people stem cell infusion, not only we actually put the cells under light to activate them. And then while we're giving people stem cells, we have the light going, focusing on different organs. Because what happens is that not only the light can make the cells more mobile and more proliferative, so they're actually gaining more potential to make offsprings. And not only that, if we shine the light on particular organs that activate certain adhesion molecules, so there's more interaction, more ability for that organ to trap the cells.
