Welcome to MEPD: the Medaka Expression Pattern Database.

This database contains Medaka gene expression data, examined through whole mount in situ hybridization or sections. The original database contained in situ data from a library generated by Felix Loosli and Jochen Wittbrodt by isolating mRNA from Medaka in different developmental stages. The library comprises 50000 clones and was sequenced in Singapore.
In addition to gene expression data in the current MEPD we incorporate regulatory sequence expression data. This means expression patterns of promoters and enhancers driving a reporter gene can be also searched for or added to MEPD.
