Researchers at Stanford University have developed a new method for manipulating gene expression in tissues and cells. This method, called “spatial gene modulation,” uses light to precisely control the expression of genes in specific areas of a tissue or cell. With this method, scientists can now study how gene expression is regulated in different areas of a tissue or cell and how this regulation affects its function. The implications of this technology are far-reaching, as it could be used to study diseases and eventually lead to new treatments.
