Recovery of MicroRNA from Stored Bone Marrow Aspirate Slides

摘要

Background:Archived bone marrow aspirate slides are almost infinite, readily available resource of biospecimens that enable retrospective molecular investigations of diseases. RNAs obtained from slides has limitations in utility because of their low quality and highly fragmented nature. MicroRNAs are small (<22 nt) noncoding RNAs with various cellular regulatory roles. Due to their small size, microRNAs are less prone to degradation and modification, therefore, can be preserved well in archived tissues.
