Chemists from Southern Methodist University (SMU) have developed a chemical probe to help scientists study the mechanics of critical signaling molecules, such as hydrogen sulfide, and to study how H2S benefits cardiovascular health.
They have demonstrated the use of this probe - a new class of live-cell fluorescent probes - for the imaging of H2S as produced by our cells during angiogenesis using confocal microscopy. This is the first time it has been done in a living system.
In this image, the fluorescent probe images endogenous H2S in endothelial cells cultured from a human umbilical vein.
