AB  - Matrix remodeling associated 5 (MXRA5) is an extracellular protein that is upregulated in several cancers, but little is known regarding its spatial and temporal localization in the developing embryo. The present study was undertaken to investigate MXRA5 transcript expression in the trunk and limb of the embryonic chick to provide groundwork for future investigation of its developmental function. In situ hybridization utilizing digoxigenin-labeled sense control and experimental antisense probes was performed in paraffin sections of chick embryos from Hamburger and Hamilton (HH) stages 18-38. MXRA5 expression was initially low and restricted in extent at the earliest stages examined, but expression increased in strength and tissue distribution with developmental age. Transcripts were largely found in cells of mesodermal origin, including gut associated mesenchyme, tendon and ligament rudiments, intervertebral discs, dermal papillae of feather buds, heart valve precursors and leaflets, as well as in appendicular joint primordia.  The present study has provided initial information on MXRA5 gene expression in the trunk and limb of early to mid-stage avian embryos. Results show that MXRA5 was expressed most strongly at sites undergoing change and remodeling of the extracellular matrix during transition of embryonic tissues into the functional adult morphology.
