Single-cell and spatial transcriptomics as novel tools for microglial research in neurodevelopment. In 1996, dysplastic cortical neurons obtained from patients with tuberous sclerosis (a rare genetic condition that causes the development of mainly benign tumours throughout the body caused by mutations in tuberous sclerosis 1 (TSC1), tuberous sclerosis 2 (TSC2), and interferon gamma (IFNγ) genes) were labelled in tissue sections with antibodies against neuronal precursors [28]. Here, IFNG is linked to neoplasm.
