(A) ChIP-seq and ATAC-seq for PRS locus putative enhancer clusters EC1.45 (p300 peaks P1 and P2), EC1.35 (S1 and S2) and EC1.25 (S3, S4, S5 and S6).
(B) Luciferase reporter assays for EC1.45, EC1.35 (S1-S2) and EC1.25 (S3-S4-S5-S6) in hCNCC (left) and hESC (right).
(C) Schematic outlining craniofacial domains at E9.5 and E11.5. BA1–2, branchial arch 1–2; FNP, frontonasal prominence; LNP, lateral nasal process; MdP, mandibular process; MNP, medial nasal process; MxP, maxillary process.
(D) In situ hybridization (ISH) for Sox9 at E9.5 and E11.5.
(E) Mouse lacZ reporter assay for EC1.45, EC1.35 (S1-S2) and EC1.25 (S3, S4, S5, S6 tested individually) at E9.5 and E11.5.
(F) HREM for EC1.45 LacZ reporter embryo at E11.5 (frontal view, upper; parasagittal section, lower). White arrow, activity in MdP.
