AbstractCranial neural crest cells (cNCCs) comprise a multipotent population of cells that migrate into the pharyngeal arches of the vertebrate embryo and differentiate into a broad range of derivatives of the craniofacial organs. Consequently, migrating cNCCs are considered as one of the most attractive candidate sources of cells for regenerative medicine. In this study, we analyzed the gene expression profiles of cNCCs at different time points after induction by conducting three independent RNA sequencing experiments. We successfully induced cNCC formation from mouse induced pluripotent stem (miPS) cells by culturing them in neural crest inducing media for 14 days. We found that these cNCCs expressed several neural crest specifier genes but were lacking some previously reported specifiers, such as paired box 3 (Pax3), msh homeobox 1 (Msx1), and Forkhead box D3 (FoxD3), which are presumed to be essential for neural crest development in the embryo. Thus, a distinct molecular network may the control gene expression in miPS-derived cNCCs. We also found that c-Myc, ETS proto-oncogene 1, transcription factor (Ets1), and sex determining region Y-box 10 (Sox10) were only detected at 14 days after induction. Therefore, we assume that these genes would be useful markers for migratory cNCCs induced from miPS cells. Eventually, these cNCCs comprised a broad spectrum of protocadherin (Pcdh) and a disintegrin and metalloproteinase with thrombospondin motifs (Adamts) family proteins, which may be crucial in their migration.

AbstractVertebrate cranial neural crest cells (CNCC) are multipotent. Proximal to the source CNCC form the cranial ganglia. Distally, in the pharyngeal arches, they give rise to the craniofacial skeleton and connective tissues. Fate choices are made as CNCC pattern into distinct destination compartments. In spite of this importance, the mechanism patterning CNCC is poorly defined. Here, we report that a novel β-catenin-controlled switch in the cell arrangement is critical in patterning CNCC. In mouse embryos, at the first pharyngeal arch axial level, membrane β-catenin levels correlate with the extent of cell-cell adhesion and thus, with a collective or a dispersed state of CNCC. Using in vitro human neural crest model and chemical modulators of β-catenin levels, we show a requirement for down-modulating β-catenin for the collective-to-dispersed switch. Similarly, in β-catenin gain of function mutant mouse embryos, CNCC fail to disperse, which may underlie their failure to populate first pharyngeal arch. Thus, we show that β-catenin-mediated regulation of CNCC tissue architecture, a previously underappreciated mechanism, underlies the patterning of CNCC into fate-specific compartments.Summary statementThe report shows a crucial step in cranial neural crest patterning. Neural crest cells invading the pharyngeal arches transition from a collective to a dispersed state. This transition in cell arrangement is dependent on membrane β-catenin levels.

Craniofacial Defects

Objective Tinagl1 has a weak genetic association with craniosynostosis, but its functions in cartilage and bone development are unknown. Knockdown of Tinagl1 in zebrafish embryos allowed an initial characterization of its potential effects on craniofacial cartilage development and a test of whether these effects could involve Wnt signaling. Results Tinagl1 knockdown resulted in dose-dependent reductions and defects in ventral pharyngeal arch cartilages as well as the ethmoid plate, a zebrafish correlate to the palate. These defects could be correlated to reduced numbers of cranial neural crest cells in the pharyngeal arches and could be reproduced with comanipulation of Tinagl1 and Wnt3a by morpholino-based knockdown. Conclusions These results suggest that Tinagl1 is required early in the proliferation or migration of cranial neural crest cells and that its effects are mediated via Wnt3a signaling. Because Wnt3a is among the Wnts that contribute to nonsyndromic cleft lip and cleft palate in mouse and man, further investigation of Tinagl1 may help to elucidate mechanisms underlying these disorders.
