Pearl microstructure and expression of shell matrix protein genes MSI31 and MSI60 in the pearl sac epithelium of Pinctada fucata by in situ hybridization. [PDF]
PLoS ONE, 2013 Expression patterns of the shell matrix protein genes MSI31 and MSI60 in the pearl sac epithelium were examined by in situ hybridization 38 days after implantation, and related to pearl quality. A pearl sac that produced a nacreous pearl showed very weak
