A quantitative and semi-automated method for determining misaligned and lagging chromosomes during mitosis.

abstract：:Cellular differentiation and lineage commitment are considered to be robust and irreversible processes during development. Recent work has shown that mouse and human fibroblasts can be reprogrammed to a pluripotent state with a combination of four transcription factors. We hypothesized that combinatorial expression of...
