How a Breakthrough in Spatial Proteomics Saved Lives

Toxic epidermal necrolysis (TEN) is a rare but devastating reaction to common medications like antibiotics or gout treatments. It begins innocuously, often as a rash, but can escalate rapidly into…

A Novel Laser-Based Method for Studying Optic Nerve Regeneration

Optic nerve regeneration is a major challenge in neurobiology due to the limited self-repair capacity of the mammalian central nervous system (CNS) and the inconsistency of traditional injury models.…
Fluorescence microscopy of sectioned tissue, showing the interface between the extensor digitorum longus muscle and the common peroneal nerve in the adult rat. Regenerative peripheral nerve interface (RPNI) at 2 weeks. Image acquired using Mica. Stained for nuclei (blue), neurofilaments (green) and S100B (red).

A Guide to Using Microscopy for Drosophila (Fruit Fly) Research

The fruit fly, typically Drosophila melanogaster, has been used as a model organism for over a century. One reason is that many disease-related genes are shared between Drosophila and humans. It is…
这些图像说明，要捕捉特定细胞中的所有 gH2Ax 病灶并进行精确计数，用多个三维光切片方法实现。

罕见疾病 CRISPR 疗法的开发与风险解除

Fyodor Urnov博士和Sadik Kassim博士最初是在ASGCT 2025会议上作这一按需演讲的，演讲的重点是遗传医学中的一个关键挑战：如何将CRISPR疗法从单一疾病解决方案扩展到平台方法，特别是针对罕见的儿科遗传疾病。Urnov 博士展示了由 Matthew Kan 博士领导的创新基因组研究所的工作，这是 IGI-Danaher Beacon for CRISPR Cures…

用于三维生物成像的集成连续切片与冷冻电镜工作流程

本场网络研讨会探讨了集成化工具如何支持从样品制备到图像分析的电子显微镜全流程。专家Andreia Pinto博士、Adrian Boey博士与Hoyin Lai博士将介绍UC Enuity超薄切片机和Aivia图像分析平台，并演示这些工具如何同时适用于常温与低温实验环境。会议内容包含阵列断层成像、基于深度学习的图像分割、以及生物成像中cryo-lift-out工作流程的实际案例解析。
