<P>The present study was carried out to understand the co-culture effect of C2C12 and 3T3-L1 preadipocyte cells on calpain, caspase, and heat shock protein (Hsp) systems. Calpains, caspases, and heat shock proteins play critical roles in the growth and development of mammalian cells. Cells were co-cultured using transwell inserts with a 0.4-μm porous membrane to separate C2C12 and 3T3-L1 preadipocyte cells. Each cell type was grown independently on the transwell plates. Following cell differentiation, inserts containing 3T3-L1 cells were transferred to C2C12 plates and inserts containing C2C12 transferred to 3T3-L1 plates. Following co-culture for 24 and 48?h, the cells in the lower well were harvested for analysis. Calpains include μ-calpain, m-calpain, and their specific inhibitor calpastatin. The expression pattern of μ-calpain did not change in the co-cultured C2C12 and 3T3-L1 cells, whereas m-capain mRNA expression significantly reduced in the 48-h co-cultured 3T3-L1 cells. Calpastatin mRNA expression significantly increased in the 48-h co-cultured C2C12 cells. Caspase-7 mRNA expression did not change in the 24- and 48-h co-cultured C2C12 and 3T3-L1 cells. Caspase-3 mRNA expression significantly reduced in the 24- and 48-h co-cultured 3T3-L1 cells; caspase-9 mRNA had a significant reduction only at 48?h, whereas caspase-9 mRNA expression significantly increased in the 48-h co-cultured C2C12 cells. Hsp27 and Hsp90 mRNA expressions are significantly reduced in the 24- and 48-h co-cultured C2C12 and 3T3-L1 cells, whereas Hsp70 mRNA expression significantly increased in the 48-h co-cultured 3T3-L1 cells. The co-culture reflects three-dimensional views of C2C12 and 3T3-L1 cell types as in vivo, which is quite distinct from the one-dimensional monocultured C2C12 and 3T3-L1 cells.</P>
