Abstract
Human brain organoids can serve as models to study myelination, a process orchestrated by oligodendrocytes. Real-time imaging provides new insights on the communication of oligodendrocytes with neurons as well as demyelination processes in patient derived organoids. PLP1, a prominent myelin protein within the central nervous system, is associated with demyelinating diseases, such as Pelizaeus-Merzbacher. In this study, we generated a stable PLP1-Citrine reporter line (fPLP1) in human induced pluripotent stem cells (iPSCs) by CRISPR/Cas9 editing. fPLP1 facilitates visualization of PLP1 expression in living brain organoids, allowing time-lapse imaging of pre-myelinating and myelinating oligodendrocytes.
