Outline of Final Research Achievements |
grimp gene plays an important role in early stage of regeneration in Enchytraeus japonensis. grimp mRNA is detected transiently from 6 to 12 h post amputation only in mesodermal stem cells called neoblasts and mesodermal lineage cells. In order to clarify the function and cellular localization of grimp protein, we took approaches for the production, purification and characterization of recombinant protein, and made polyclonal antibodies. By immunohistochemistry, we found that grimp protein is expressed in the mesodermal cells in regeneration bud from 6-24 h post amputation. The target protein of the antibodies was detected by the western blotting at around predicted size.
