1 Exposure to retinoic acid before or after the onset of somitogenesis reveals separate effects on rhombomeric segmentation and 3" HoxB gene expression domains. Tretinoin homeobox B cluster Mus musculus
2 In contrast, exposure to RA at early somite stages results in near-normal rhombomeric segmentation; rhombomeric gene expression domains indicate that only rhombomere 2 has changed its genetic identity to that of rhombomere 4, the other preotic segments showing normal expression patterns for HoxB genes and Krox-20. Tretinoin homeobox B cluster Mus musculus
