newt mitosis - NIH

   Image of a newt lung cell stained with fluorescent dyes undergoing MITOSIS.

  The green stained material are the microtubules that form the mitotic spindle, the material stained red is the cell membrane and some components of the cytoplasm near it, and the material stained light blue are the chromosomes.

  According to the NIH, "The scientists use newt lung cells in their studies because these cells are large, easy to see into, and are biochemically similar to human lung cells."
