Using an ultrafast femtosecond laser, researchers were able to label, draw patterns on, and remove individual melanocytes cells from a species of frog tadpole (Xenopus) without damaging surrounding cells and tissues. Melanocytes are the cells responsible for skin pigment; they also are descendants of a specific type of stem cell that has regenerative potential and other characteristics similar to some cancer cells.
