Figure Lengend Snippet: (a) Transcriptomic analysis of the time-course differentiation process. Loss of pluripotency markers is visible over time. (b) A GM25256 hiPSC colony after 12 h of RA-induced differentiation. The red arrow indicates filopodium-like membrane protrusion at colony periphery. The green arrow indicates an intercellular gap. (c) A GM25256 hiPSC colony after 24 h of RA-induced differentiation. (d) A GM25256 hiPSC colony after 48 h of RA-induced differentiation. The red arrow indicates a jagged colony boundary. ( e ) A GM25256 hiPSC colony after 96 h of RA-induced differentiation. The red arrow indicates an intercellular gap near the colony periphery. ( f ) A H9 hESC colony both untreated and after 24 h of RA-induced differentiation. P undiff was measured by DeepHOPE. (g) Ratio of H9 hESC colonies with average P undiff over 0.5. (h) A KOLF2.1J hiPSC colony both untreated and after 24 h of RA-induced differentiation. P undiff was measured by DeepHOPE. (i) Ratio of KOLF2.1J hiPSC colonies with average P undiff over 0.5. Scale bar (B to H) = 50 μm.
Article Snippet: The human embryonic stem cell line H9 (WA09, WiCell) and human iPSCs lines GM25256 (Coriell Institute) and KOLF2.1J (The Jackson Laboratory) were used to generate the base model for this study.
