| Abstract: |
| Pomacea canaliculata’s muscle，mantle，kidney and brain tissues were aseptic separated by
trypsin digestion and grinding method. Cells were primary cultured with DMEM，F12 and modified 1640 medium.
The growing status was observed under light microscope. The cell viability was determined by MTT method. After a
certain time，chromosome preparation and chromosome karyotype analysis were conducted. Results showed that there
was significant difference in histocytes viability among different culture medium. The better viability of mantle and
muscle histocytes was cultured with DMEM medium containing hydrolyzed milk protein. The better viability of mantle
and brain histocytes was cultured with M199 medium. In karyotype analysis，results showed that P. canaliculata was
diploid（ 2n = 28，NF = 56）. The nuclear type was 2B and the nuclear asymmetry coefficient was 66.4% |
