Furthermore, three fixatives were tested with each of the rehydration fluids. Meniscus (fibrocartilage), skin, and a placenta were used for this study. The rehydration and fixation procedures were uniform for all methods. Materials and methods In 1997, the German Institute for Archaeology headed an excavation of the tombs of the nobles in Thebes-West, Upper Egypt. At this time, three types of tissues were sampled from different mummies: meniscus (fibrocartilage), skin, and placenta. Archaeological findings suggest that the mummies dated from the New Kingdom (approxi- mately 1550-1080 BC). Skin Skin sections showed particularly good tissue preservation, although cellular outlines were never distinct. Although much of the epidermis had already separated from the dermis, the remaining epidermis often was preserved well (Fig. 1). The basal epithelial cells were packed with melanin as expected for specimens of Negroid origin. In the dermis, the hair follicles, hair, and sebaceous and sweat glands were readily apparent (Fig. 2). Blood vessels, but no red blood cells, and small peripheral nerves were identified unambiguously (Fig. 3). The subcutaneous layer showed loose connective tissue fibers attached to the dermis, and fat cell remnants were observed. To evaluate the influence of postmortum tissue decay by micro-organisms, the samples were tested for the presence of fungi using silver staining.
