Studysummary This study found that mouse FLRG protein, a secreted glycoprotein, is expressed in certain tissues and plays a role distinct from follistatin during wound healing, suggesting different functions in vivo.

The study characterized the murine follistatin-related gene (FLRG) protein, revealing it as a secreted glycoprotein with high expression in the lung, testis, uterus, and skin. FLRG was found in the basement membrane and around blood vessels, with its mRNA expression induced by various growth factors in keratinocytes and fibroblasts. Both FLRG and follistatin were expressed during wound healing but showed different distribution patterns, suggesting distinct roles for these activin-binding proteins in vivo.
