 Spatial transcriptomics is a rapidly growing field that allows researchers to study gene expression patterns at the cellular level while taking into account the surrounding environment. This technology has been used to gain insights into neurological diseases such as Alzheimer's and Parkinson's, as well as cancer. It also provides a way to analyze the spatial distribution of genetic markers and other molecular components within tissues or organs.
