The Spindle Assembly and Spindle Position Checkpoints
Annual Review of Genetics, 2003▪ Abstract The mitotic spindle segregates chromosomes to opposite ends of the cell in preparation for cell division. Chromosome attachment to the spindle is monitored by the spindle assembly checkpoint, and at least in yeast cells, penetration of one spindle pole into the bud is monitored by the spindle position checkpoint.

Forty-three patients who initially presented with Krikenberg's spindles but with no glaucomatous field defects were observed for an average of 5.8 years in an attempt to evaluate the prognostic implication of spindle presence. Twenty-two of the patients had been followed for a minimum of five years.

Sleep spindles are discussed from various viewpoints. The definition of this pattern has been debated and requires clarification. There is evidence of two spindle types around 14 c/s and 12 c/s. The existence of a third spindle type (around 10 c/s) is controversial.

Meiotic spindle, spindle checkpoint and embryonic aneuploidy
Frontiers in Bioscience, 2006In mitosis, a spindle checkpoint plays important roles at the metaphase-anaphase transition to ensure the formation of a bipolar spindle, the completion of connecting chromosomes to microtubules and the alignment of all chromosomes at the spindle equator before initiation of anaphase.

The Mechanical Spindle: A Replica of the Mammalian Muscle Spindle
Proceedings of the 15th Annual International Conference of the IEEE Engineering in Medicine and Biology Societ, 1995The goal of the recently initiated Anthroform Arm Project is to understand the manipulation capabilities of the human arm through the development of a dynamically accurate replica arm. Previous attempts have focussed on manipulator kinematics, and have neglected dynamics and controller designs.

Prior to sister-chromatid separation, the spindle checkpoint inhibits cell-cycle progression in response to a signal generated by mitotic spindle damage or by chromosomes that have not attached to microtubules. Recent work has shown that the spindle checkpoint inhibits cell-cycle progression by direct binding of components of the spindle checkpoint ...

Nature, 1971
OSTERGREN1 suggested that, before and during metaphase, the mitotic and meiotic chromosomes are subjected to pole-directed forces α, which orient the chromosomes at the equator of the spindle and separate them at anaphase. He also postulated a centrifugal force, γ, moving the chromosomes to the periphery of the metaphase plate; but he could suggest no ...

Spindle membranes and spindle architecture in invertebrates
Micron, 1995Abstract Membranes are consistent components of spindles in plants and animals. Depending on the species, they either form layers at the periphery of the spindle, are scattered throughout the spindle area or can be observed in both locations. This review aims to provide a survey of the arrangements and functions of membranes associated with the ...
