Abstract
In this pilot study we changed several pre-analytical variables of bone marrow trephine biopsy processing with the task to achieve not only a preservation of morphology and antigens but also of nucleic acids. The changes involved employment of a newly established decalcification solution in conjunction with a short fixation time (2 h after receiving the specimens) and performance of decalcification at 37 °C. The comparison of the obtained results from three specimens with those of our routinely established protocol unequivocally revealed that the novel decalcification solution results in a superior preservation of nucleic acids, with only slight differences in preservation of morphology and cellular antigens. These encouraging results imply that this novel decalcification solution will allow a widely accepted standardization of bone marrow trephine biopsy processing.
