Abstract
Recently emerged spatial transcriptomics approaches combine the RNA sequencing (RNA-Seq) with spatial localization to reveal the spatial heterogeneity of transcriptome in pancreatic islet. However, the interrogation of the transcriptomic expression in a single cell is missing, particularly the spatial distribution of each RNA molecule. Here we proposed a quantitative approach to quantify the spatial distribution of RNA molecules in a single cell, and gave a case study to investigate the miRNA expression in single ? cells obtained from human pancreatic tissues. A multi-dimensional quantitative model was established to describe the spatial distribution of individual RNAs as a library of “features”, which includes RNA expression, locations, clustering/dispersion, and reciprocal positions. In particular, the degree of RNA clustering/dispersion was described by the mathematical model of clusters, i.e. Ripley's H function. Extracted features are then analyzed by statistical distribution modelling and supervised machine learning. Machine learning enables the classification of 3 groups of ? cells (control, T1D, and AAb+) using spatial transcriptomic features with high accuracy (65%±3%). Furthermore, it offers quantitative evaluation of those distinctive features contributing to the classification and phenotyping. All evidence suggests the spatial heterogeneity of transcriptome of ? cells in T1D, and this transcriptomic disparity has been leveraged to classify ? cells into different pathological conditions. This work will not only disclose fundamental mechanisms that are associated with ? cell survival in T1D; more practically, it could lead to important transcriptomic features of ? cells that could have clinical relevance in stratifying the T1D phenotypes.
