For the neural crest nerds: we love looking into transcriptional programs in single NCC cells. However, selective ribosomal modifications refine gene expression programs at a different scale. Here is our story about modified ribosomes in neural crest fate selection: www.nature.com/articles/s41...

Saving face: SALL4 is required for early specification of craniofacial precursors This Research Highlight showcases work by Martina Demurtas, Marco Trizzino (@marcotrizzino.bsky.social) and colleagues: journals.biologists.com/dev/article/...
Figure 7: CNCC induction and specification are impaired in SALL4-het-KO. (A) Relative mRNA expression of canonical CNCC markers in SALL4-WT and SALL4-het-KO cells at day 14 (n=2). Statistical significance was assessed using unpaired Student's t-test. 18S rRNA was used to normalise. Data are mean±s.e.m. (B) Flow cytometry for the CNCC surface marker CD99 in SALL4-WT and SALL4-het-KO (clone F1) CNCCs at day 14. (C) Volcano plot of genes differentially expressed in SALL4-het-KO relative to SALL4-WT in CNCCs (day 14). Blue dots (n=659) represent downregulated genes with Padj<0.05 and log2FoldChange<−1.5. Purple dots (n=447) represent upregulated genes with Padj<0.05 and log2FoldChange>1.5. (D,E) GO term enrichment for downregulated (D) and upregulated (E) genes in SALL4-het-KO cells (FDR<0.05). (F) Heatmap displaying the expression of canonical epithelial-to-mesenchymal transition (EMT) markers in SALL4-WT and SALL4-het-KO cells (day 14).
