简介:血小板颗粒缺陷导致出血性疾病,但其特异性诊断通常需要全载片透射电子显微镜检查,这通常是不可用的,并具有许多重要的局限性。我们最近提出了使用先进形式的荧光显微镜-所谓的“超分辨率”显微镜-作为一种可能的解决方案。覆盖的领域:在这篇特别报道中,我们回顾了血小板颗粒缺陷的诊断,并讨论了荧光显微镜的最新发展如何有助于改善这些疾病和相关疾病的诊断方法。特别是,我们得出结论,超分辨率荧光显微镜可能具有优势,在此应用中的透射电子显微镜。专家评论:超分辨率显微镜的价值已在研究中得到充分证明,但其在诊断应用中的潜力还有待进一步探索。血液学是一个特别可能受益的领域,因为样品制备相对简单。我们预计,必要仪器的成本将继续迅速下降,使这些技术广泛提供给临床医生。
Introduction: Platelet granule deficiencies lead to bleeding disorders, but their specific diagnosis typically requires whole mount transmission electron microscopy, which is often not available and has a number of important limitations. We recently proposed the use of advanced forms of fluorescence microscopy – the so-called ‘super-resolution’ microscopies – as a possible solution. Areas covered: In this special report, we review the diagnosis of platelet granule deficiencies, and discuss how recent developments in fluorescence microscopy may be useful in improving diagnostic approaches to these and related disorders. In particular, we conclude that super-resolution fluorescence microscopy may have advantages over transmission electron microscopy in this application. Expert commentary: The value of the super-resolution microscopies has been amply demonstrated in research; however, their potential in diagnostic applications is ripe for further exploration. Hematology is a field particularly likely to benefit because of the relative simplicity of sample preparation. We anticipate that the costs of the necessary instrumentation will continue to fall rapidly, making these technologies widely accessible to clinicians.
