Dynamics expression of c-kit protein in gametogenesis of Atractomorpha heteroptera

By using immunohistochemistry and biostatistics, the special expression dynamics of c-kit protein in gametogenesis were studied by rearing Atractomorpha heteroptera Bei-Bienko in natural conditions. The results showed that: (1) In spermatogenesis, there were different expression levels of c-kit protein in spermatogonia, primary spermatocytes, secondd spermatocytes and mature sperms, and the biggest positive granules were found at the end of spermary; (2) In oogenesis, there were different expression levels of c-kit protein from the 1st to 6th stage of oocytes but the positive granules disappeared with the following vitellogenesis; (3) The c-kit positive granules were also found in follicular cells and the gland cells of oviduct and spermathecae; (4) The dynamic change of c-kit positive expression showed that it became stronger in young periods than in old periods not only in spermatogenesis but also in oogenesis. All in all, the special expression of c-kit protein implied that those proteins might participated in the stage regulation and play crucial role in gametogenesis.
