spindle-shape muscle cells shown depicted in bright green and blue against a black background

Scientists have transformed cancer cells into healthy muscle tissue in the lab using CRISPR gene-editing technology — and they hope new cancer treatments can be built on the back of this experiment.

In a study published Aug. 28 in the journal PNAS, researchers found that disabling a particular protein complex in cells of rhabdomyosarcoma (RMS) — a rare cancer in skeletal muscle tissue that mainly affects children under age 10 — in the laboratory causes the tumor cells to turn into healthy muscle cells.
