Web15 hours ago · At the TAD level, we obtained ~ 1000 TADs in both CFM and CAM, but only a few TAD boundaries were changed, which agreed with the findings during iPax7 progenitor differentiation and chicken folliculogenesis [22, 27]. This confirmed that TAD is a genuine unit of chromatin packing . At loop level, we identified ~ 10,000 loops in both … WebApr 14, 2024 · Here, we directly visualized chromatin looping at the Fbn2 TAD in mouse embryonic stem cells using super-resolution live-cell imaging and quantified looping dynamics by Bayesian inference. Unexpectedly, the Fbn2 loop was both rare and dynamic, with a looped fraction of approximately 3 to 6.5% and a median loop lifetime of …
