Decoding cell division’s mysterious spindle matrix

17 septiembre 2015

Every biology class learns about mitosis, which involves copying each of a cell’s DNA-containing chromosomes, then separating them into two newly created cells. The act of chromosome separation is facilitated by a structure called the spindle, a framework of interconnected fibrous microtubules. The spindle also contains other densely packed materials, referred to as the spindle matrix, believed to be important for cell division. New work zeroes in on one particular spindle matrix protein, called BuGZ.
