Abstract:

Spatial transcriptomics provides spatially gene expression profiles in tissues via sequencing or imaging. Combined with algorithms for image analysis and modeling, spatial transcriptomics can offer the locations of genes and cell types in tissues. Here, we summarize the technical  principles and data exploring methods of spatial transcriptomics. We divide the experiment technologies into three categories and describe their characteristics in detail and introduce the principle and application of  various data exploring methods for pre-processing, basic
bioinformation analysis, cell annotation and interpreting specific tissue microenvironment. Finally, we highlight the
limitations and future development of spatial  transcriptomics, hoping to provide assistance to  researchers in basic medicine and molecular biology fields.
