Project description:We identified diffuse lesions made of BRAF V600E-mutant CD34-immunopositive stellar cells in human samples resected to cure drug-resistant focal epilepsy. We performed single-nuclei RNAseq 5' 10X on three human brain samples (two BRAF mutant samples and one BRAF wildtype sample as control) in order to identify the molecular phenotype of CD34+ cells.
