### Gene expression in the mandibular and maxillary arches _Hand2_ is expressed in the distal mesenchyme of the mandibular arch at E10.5. At E12.5, it is expressed in the osteogenic mesenchyme adjacent to the Meckel’s cartilage, and the tongue mesenchyme. At E14.5, _Hand2_ is expressed in the differentiated osteoblasts of the mandible, the tongue mesenchyme, and the sublingual muscles. | E10.5 | E12.5 | E14.5 | |-------|-------|-------| | {width=280 height=214} | {width=280 height=214} | {width=280 height=214} | |  Distal mandibular |  Osteogenic progenitors |  Mandibular differentiated | | mesenchyme | adjacent to Meckel’s cartilage | osteoblasts | | |  Tongue mesenchyme |  Tongue mesenchyme | | | |  Sublingual muscles | #### Sources: - Funato N et al., Development 2009 136: 615-625 - Ruest LB, et al., Dev Biol. 2003 May 15;257(2):263-77 - Clouthier DE, et al., Dev Biol. 2000 Jan 1;217(1):10-24 - Diez-Roux G, et al., PLoS Biol. 2011;9(1):e1000582 - Ikle JM, et al., Dev Biol. 2012 Aug 1;368(1):118-26 - Unpublished data from [Chai's Lab, University of Southern California.](http://face.usc.edu/).
