When Glia Meet Induced Pluripotent Stem Cells (iPSCs)
Abstract The importance of glial cells, mainly astrocytes, oligodendrocytes, and microglia, in the central nervous system (CNS) has been increasingly appreciated. Recent advances have demonstrated the diversity of glial cells and their contribution to human CNS development, normal CNS functions, and disease progression. The uniqueness of human glial cells is…
Novel Rett syndrome variant shines light on n
Rett syndrome is a rare devastating neurological disorder that primarily affects young girls and manifests as an impaired ability to walk and talk, along with characteristic ‘hand-wringing’ movements, seizures, and cognitive disability. This incurable condition results from mutations in the methyl-CpG binding protein 2 (MECP2) gene that impairs the role…
