FIG. 6.
Result of post-fusion tracking of Oct4-GFP expression in fused cells. (a) A fused cell on a micro-slit at the start of time-lapse imaging. (b) The hybrid cell in (a) undergoes cell division after 7 h post fusion. (c) One of the daughter cell formed in the first cell division expresses the green Oct4-GFP fluorescence. (d) The cell marked “d1” in (c) divides into two granddaughter cells (g1, g2). (e) Both granddaughter cells express the green Oct4-GFP fluorescence 48 h post fusion. (f) Great granddaughter cells formed by cells in (e) express Oct4-GFP 63 h post fusion. (g) Tree diagram summarizing the time-transiting information of a fused cell resulting in green fluorescence.
