title: Histochemical observations on bone marrow biopsies embedded in glycol methacrylate (Technovit 7100).
abstract: Preparation of sections from undecalcified bone marrow biopsies embedded in glycol methacrylate (GMA, Technovit 7100) is reported. The beneficial effect of vacuum for a better penetration of resin into the hard tissue is assumed. Preserved details of 2- to 3-microns-thick sections of bone marrow specimens from various haematological malignancies yield a proper diagnosis and use of some histochemical methods on immature leukaemic cells is also possible. The use of embedding medium Technovit 7100 in the bone marrow histopathology is widely recommended for its simple, quick usage and non-toxic properties. An additional advantage is that blocks can be cut with ordinary steel knives (Histoknife H).
