Results of histochemical tests performed on the end of lip callus: a single-layered epidermis and idioblasts in parenchyma cells (localized in the middle and at the bottom of tissue, TBO). b-c the irregular globules with heterogeneous nature (arrows) differing between cells (magnifications of a). d-f huge amounts of lipids in the epidermis, subepidermis, and in some parenchyma cells (SBB) with the different levels of black color between cells reflecting the various stages of lipids’ accumulation. g papillate epidermis of lip apex stained for lipids (SBB). ie—inner epidermis, n—nucleus, pa—parenchyma, r—idioblasts with raphides, se—subepidermis
