Expression of Mir133b in mouse facial muscles at E12.5. ISH analysis in frozen frontal sections through the head of E12.5 mouse embryos. (A–C) Mir133b is weakly expressed in the nasal epithelium (ne; A), mystacial vibrissae (mv; B), and maxilla (mx); (D–F). (mx); (D–F). Mir133b is strongly expressed in facial muscles, including the masseter (ma), and in the muscles of the eye (em; D) and tongue muscle (t; E–I) Expression is not observed in the palatal shelves (ps; E,F). (G–I) Posterior expression continues continues in the tongue muscles. e, eye; oc, oral cavity.
