Glo-In-One-v2: Holistic Identification of Glomerular Cells, Tissues, and Lesions in Human and Mouse Histopathology

  • 基于动态头部架构,统一处理14类肾小球结构与病变的细粒度分割。
  • 在23,529个肾小球数据上实现76.5%平均Dice系数,跨物种迁移提升3%以上准确率。
  • 开源模型与权重,适用于人类与小鼠病理图像分析,助力肾脏疾病研究。

传统肾小球组织与病变分割依赖专家进行详细形态学评估,耗时且存在观察者差异。我们此前开发了Glo-In-One工具包用于整合检测与分割肾小球。本研究在此基础上推出Glo-In-One-v2,具备细粒度分割能力,构建了涵盖人与小鼠肾病病理数据的大型标注数据集,共包含23,529个标注肾小球,覆盖14类组织区域、细胞及病变。提出一种单动态头深度学习架构,可在部分标注图像上完成14类目标的分割。模型基于368张标注的肾全片图像(WSIs)训练,识别5类肾小球内部组织:鲍曼囊、血管球毛细血管丛、基质、系膜细胞与足细胞;同时分割9类病变:粘连、囊滴、全局硬化、透明变性、系膜溶解、微动脉瘤、结节硬化、系膜扩张及节段硬化。肾小球分割模型性能优于基线方法,平均Dice相似系数(DSC)达76.5%。此外,通过从啮齿类向人类的迁移学习,使各类病变分割的平均精度(以Dice分数衡量)提升超过3%。Glo-In-One-v2模型与训练权重已公开发布于https://github.com/hrlblab/Glo-In-One_v2。

原文摘要 · Abstract (English)

Segmenting glomerular intraglomerular tissue and lesions traditionally depends on detailed morphological evaluations by expert nephropathologists, a labor-intensive process susceptible to interobserver variability. Our group previously developed the Glo-In-One toolkit for integrated detection and segmentation of glomeruli. In this study, we leverage the Glo-In-One toolkit to version 2 with fine-grained segmentation capabilities, curating 14 distinct labels for tissue regions, cells, and lesions across a dataset of 23,529 annotated glomeruli across human and mouse histopathology data. To our knowledge, this dataset is among the largest of its kind to date.In this study, we present a single dynamic head deep learning architecture designed to segment 14 classes within partially labeled images of human and mouse pathology data. Our model was trained using a training set derived from 368 annotated kidney whole-slide images (WSIs) to identify 5 key intraglomerular tissues covering Bowman's capsule, glomerular tuft, mesangium, mesangial cells, and podocytes. Additionally, the network segments 9 glomerular lesion classes including adhesion, capsular drop, global sclerosis, hyalinosis, mesangial lysis, microaneurysm, nodular sclerosis, mesangial expansion, and segmental sclerosis. The glomerulus segmentation model achieved a decent performance compared with baselines, and achieved a 76.5 % average Dice Similarity Coefficient (DSC). Additional, transfer learning from rodent to human for glomerular lesion segmentation model has enhanced the average segmentation accuracy across different types of lesions by more than 3 %, as measured by Dice scores. The Glo-In-One-v2 model and trained weight have been made publicly available at https: //github.com/hrlblab/Glo-In-One_v2.
