Genome editing: new opportunities

Scientists from California have developed a method for relatively effective editing of the genome of T-lymphocytes. In fact, they were able to use the CRISPR/Cas9 system, which could not be used before due to difficulties with the delivery of system components to lymphocytes.

Scientists have "armed" living cells with tiny lasers

So far, it has been possible to introduce lasers only into artificially grown cells. However, researchers have already begun developing a technology that will allow them to be introduced into the cells of the body's tissues, which can be used to track the movement of cells of various types.
