title: In vitro explant culture of mantle epithelium of freshwater pearl mussel.
abstract: The in vitro culture of nacre secreting pallial mantle explants of freshwater pearl producing mussel, Lamellidens marginalis (Lamarck) included depuration of pearl mussels with different physical and chemical agents to eradicate various commensals, removal of pallial mantle ribbon, aseptic preparation of explants from the ribbon and transfer of those explants into tissue culture petri dishes. Special synthetic tissue culture media enriched with additives viz., inactivated calf fetal serum and antibiotics were poured into plates with explants. The culture plates were incubated at 30 degrees C in a CO2 incubator at 5%, CO2. The cultures could be maintained for 42-45 days without any contamination. After 12 hr epithelial like cells began to migrate out and formed a complete cell sheet surrounding the explant within 12-15 days. The epithelial cells in the culture indicated functional viability as subsequently after 38-40 days of culture, typical aragonitic 'nacre' crystals of CaCO3 could be observed throughout the culture plates.
