Short communicationExpression patterns of the hatching enzyme genes during embryonic development of tilapia

- The developmental expression patterns of the hatching enzyme genes of tilapia, including TLCE and THCE, were studied.
- The expression of TLCE was first evident at gastrula and its expression level peaked at hatching.
- The developmental expression patterns of THCE are similar to that of TLCE.
- This study provided an insight into the hatching mechanism of the mouth-brooding tilapia embryos.
