Generation of induced pluripotent stem cells is a reproducible but inefficient procedure. While genomic approaches have previously been used to study reprogramming, they average measurements across a large population of cells, the majority of which fail to induce pluripotency. Here, we used high-resolution, live time–lapse imaging to trace the reprogramming process from single donor cells to pluripotency factor positive colonies. Tracing back successfully reprogrammed colonies, we calculate a normalized cell-of-origin reprogramming efficiency that is limited to the pool of responding cells that form colonies. Our data provided a detailed physical description of the specific characteristics of reprogramming populations and reveal a robust, sequential trajectory from a somatic morphology and proliferative index to those of pluripotent cells, suggestive of an early specifying event. Our results clarify and expand previously proposed theoretical models, and provide important new insights into the still poorly defined process of direct reprogramming.
