A breakthrough paper has been published describing researchers’ invention of a miniaturized biomedical testing device for exosomes. «Exosomes are minuscule membrane vesicles — or sacs — released from most, if not all, cell types, including cancer cells,» said one chemist. «They were once thought to be trash bags containing unwanted cellular contents. However, in the past decade scientists realized that exosomes play important roles in many biological functions through capsuling and delivering molecular messages in the form of nucleic acids and proteins from the donor cells to affect the functions of nearby or distant cells.»
