I believe that they are formed by the Centrioles in the cell. These centrioles are found inside (encased) in the centrosomes. They combine microtubles and associated proteins (such as Aurora A) to strengthen the spindle fibers.
the spindle fibers. Spindle fibers are essential for separating the chromosomes during cell division. Without proper spindle formation, the chromosomes would not be able to align and segregate correctly between the two daughter cells.
Spindle fibers
During the metaphase of cell division, the spindle fibers radiate from the centrioles at the opposite poles of the cell. When the spindle fibers start to pull the chromosomes to opposite poles, this marks the anaphase of cell division.
Spindle fibers form during the prophase stage of meiosis 1.
Spindle fibers begin to disappear in the anaphase of mitosis or meiosis. During anaphase, the sister chromatids separate and move towards opposite poles of the cell, leading to the disassembly of the spindle fibers.
The answer is Spindle Fibers.
The Centrosome. It forms Centrioles which form spindle fibers. Some of the spindle fibers attach to the Kinetochore located on the Centromere of chromosomes. The spindle fibers work in conjunction with motor proteins to facilitate disjunction.

Animal cells have spindle fibers in them.
Spindle fibers. These structures form the mitotic spindle and play a crucial role in separating chromosomes during cell division.
Thespindle fibres are formed by the centrosomes not the cenrioles.The centrioles come to the MTCs ( micro tubules organising centers) which are present in the centrosomes which make up the spindle fibers on which the chromosomes are held.
The organelle responsible for forming spindle fibers during cell division is the centrosome. The centrosome is composed of two centrioles and plays a critical role in organizing and anchoring the spindle fibers that help separate the chromosomes during mitosis.
The centrioles in animal cells form the asters and the spindle fibers.
