Fig. 6. Luminal epithelial cells and myoepithelial cells can deposit both 
3-chain and 5-chain of laminin but only myoepithelial cells can deposit laminin-1 chain. Luminal epithelial cells (a,c,e) and myoepithelial cells (b,d,f) embedded in rBM were stained for laminin 1 (a,b; green), laminin 3 (c,d; green) and laminin 5 (e,f; green). Both luminal epithelial cells and myoepithelial cells deposit a basement membrane except for the lack of 1-chain deposition by the former. Nuclear stain, red. (bar, 25 µm).
