Abstract

This study contains intravital microscopy (IVM) data examining the microarchitecture of acellular kidney scaffolds. Acellular scaffolds are cell-free collagen-based matrices derived from native organs that can be used as templates for regenerative medicine applications. This data set contains in vivo assays that evaluate the effectiveness of decellularization and how these acellular nephron compartments perform in the post-transplantation environment. Qualitative and quantitative assessments of scaffold DNA concentrations, tissue fluorescence signals, and structural and functional integrities of decellularized tubular and peritubular capillary segments were acquired and compared to the native (non-transplanted) organ. Cohorts of 2-3-month-old male Sprague Dawley rats were used: non-transplanted (n = 4), transplanted day 0 (n = 4), transplanted day 1 (n = 4), transplanted day 2 (n = 4), and transplanted day 7 (n = 4). Micrographs and supporting measurements are provided to illustrate IVM processes used to perform this study and are publicly available in a data repository to assist scientific reproducibility and extend the use of this powerful imaging application to analyze other scaffold systems. Measurements(s) DNA quantification • tissue fluorescence • microvascular leakage • tubular and peritubular capillary integrity Technology Type(s) intravital microscopy • multiphoton microscopy • UV-visible spectroscopy Sample Characterization(s) rats • native and decellularized kidneys.

摘要

本研究包含使用活体显微镜 (IVM) 观察去细胞肾脏支架微观结构的数据。去细胞支架是无细胞的胶原基基质,源自天然器官,可作为再生医学应用的模板。该数据集包含评估去细胞化效果的体内测定,以及这些去细胞肾单位在移植后环境中的性能。对支架 DNA 浓度、组织荧光信号以及去细胞化管状和小管周毛细血管段的结构和功能完整性进行定性和定量评估,并与天然(未移植)器官进行比较。使用 2-3 个月大的雄性 Sprague Dawley 大鼠进行实验:未移植(n = 4)、移植后 0 天(n = 4)、移植后 1 天(n = 4)、移植后 2 天(n = 4)和移植后 7 天(n = 4)。提供了显微镜照片和支持性测量结果,以说明用于进行本研究的 IVM 过程,并在数据存储库中公开,以协助科学重现性并扩展这种强大成像应用的使用范围,以分析其他支架系统。测量值 DNA 定量 • 组织荧光 • 微血管渗漏 • 管状和小管周毛细血管完整性 技术类型活体显微镜 • 多光子显微镜 • UV-可见光谱 样本特征大鼠 • 天然和去细胞肾脏。
