Spindle fibers form a protein structure that divides the genetic material in a cell. The spindle is necessary to equally divide the chromosomes in a parental cell into two daughter cells during both types of nuclear division: mitosis and meiosis. During mitosis, the spindle fibers are called the...

I Kosaku,S Hidemi,N Hiroshi,A Natsue 摘要: Meiotic spindle and chromosome movements were studied during spermatocyte divisions in Chrysochraon japonicus and Trilophidia annulata with a sensitive polarizing microscope. When the nuclear envelope disintegrated, birefringent astral fibers invaded the karyo...
However, we illustrate the greater power of ExM protocols used to study the mitotic spindle structure, when compared to immunofluorescence without expansion, which enable better structural characterization of defined structures within the mitotic spindle, such as bridging fibers which link two sister k-...
A network of cell fibers that forms in the nucleus during cell division. Duplicate strands of chromosomes attach along the center of the spindle before separating and moving to opposite ends of the cell. See more atmeiosis,mitosis. The American Heritage® Student Science Dictionary, Second Editio...
