Project description:During development, neural crest cells are induced by signaling events at the neural plate border of all vertebrate embryos. Initially arising within the central nervous system, NC cells subsequently undergo an epithelial to mesenchymal transition to migrate into the periphery, where they differentiate into diverse cell types. Here we provide evidence that postnatal human epidermal keratinocytes, in response to FGF2 and IGF1 signals, can be reprogrammed toward a neural crest fate. Genome-wide transcriptome analyses show that keratinocyte-derived NC cells are similar to those derived from human embryonic stem cells. Moreover, they give rise in vitro and in vivo to neural crest derivatives such as peripheral neurons, melanocytes, Schwann cells and mesenchymal cells (osteocytes, chondrocytes, adipocytes and smooth muscle). By demonstrating that human KRT14+ keratinocytes can form neural crest cells, even from clones of single cells, our results have important implications in stem cell biology and regenerative medicine.

Project description:Schwann cell precursors (SCPs) are nerve-associated progenitors that not only can generate myelinating and non-myelinating Schwann cells but also are multipotent like the neural crest cells from which they originate. SCPs are omnipresent along outgrowing peripheral nerves throughout the body of vertebrate embryos. By using single-cell transcriptomics to generate the atlas of the entire neural crest lineage, we show that early SCPs and late migratory crest have similar transcriptional profiles characterized by a multipotent “hub” state containing cells biased towards traditional neural crest fates. SCPs keep diverging from the neural crest after being primed towards terminal Schwann cell and other fates, with different subtypes residing in distinct anatomical locations. Functional experiments using CRISPR-Cas9 loss-of-function further show that knock-out of the hub gene Sox8 causes defects in neural crest-derived cells along peripheral nerves by facilitating differentiation of SCPs towards sympathoadrenal fates. Finally, specific tumour populations found in melanoma, neurofibroma and neuroblastoma map to different stages of SCP/Schwann cell development. Overall, SCPs resemble migrating neural crest cells that maintain multipotency and become transcriptionally primed toward distinct lineages.

Project description:The embryonic ectoderm gives rise to four fates: neural, neural crest, placodal and epidermal. The derivatives of these fates give rise to the entire vertebrate nervous system and skin. To explore how these cell fates emerge, we profiled single cell chromatin accessibility in the chick embryonic ectoderm at five developmental timepoints.

Project description:Melanocytes are pigment-producing cells of neural crest origin responsible for protecting the skin against UV-irradiation. Melanocyte dysfunction leads to pigmentation defects including albinism, vitiligo, and piebaldism and is a key feature of systemic pathologies such as Hermansky-Pudlak (HP) and Chediak-Higashi (CH) Syndromes. Pluripotent stem cell technology offers a novel approach for studying human melanocyte development and disease. Here we report that timed exposure to activators of WNT, BMP and EDN3 signaling triggers the sequential induction of neural crest and melanocyte precursor fates under dual-SMAD inhibition conditions. Using a SOX10::GFP hESC reporter line, we demonstrate that the temporal onset of WNT activation is particularly critical for human neural crest induction. Surprisingly, suppression of BMP signaling does reduce neural crest yield. Subsequent differentiation of hESC-derived melanocyte precursors under defined conditions yields pure populations of pigmented cells matching the molecular and functional properties of adult melanocytes. Melanocytes from patient-specific iPSCs faithfully reproduce the ultrastructural features of the HP- and CH-specific pigmentation defects with minimal variability across lines. Our data define a highly specific requirement for WNT signaling during neural crest induction and enable the generation of pure populations of hiPSC-derived melanocytes for faithful modeling of human pigmentation disorders. Total RNA obtained from a timecourse of Dual SMAD Inhibition (DSi), Neural Crest (NC), and Melanocyte (BE) differentiation of human embryonic stem cells in triplicate.

Project description:We describe a so far uncharacterized, embryonic and self-renewing Neural Plate Border Stem Cell (NBSC) population with the capacity to differentiate into central nervous and neural crest lineages. NBSCs can be obtained by neural transcription factor-mediated reprogramming (BRN2, SOX2, KLF4, and ZIC3) of human adult dermal fibroblasts and peripheral blood cells (induced Neural Plate Border Stem Cells, iNBSCs) or by directed differentiation from human induced pluripotent stem cells. Moreover, human (i)NBSCs share molecular and functional features with an endogenous NBSC population isolated from neural folds of E8.5 mouse embryos. Upon differentiation, iNBSCs give rise to either (1) radial glia-type stem cells, dopaminergic and serotonergic neurons, motoneurons, astrocytes, and oligodendrocytes or (2) cells from the neural crest lineage. Here we provide array-based expression data of primary mouse Neural Plate Border Stem Cells (pNBSCs) derived from E8.5 mouse embryos and radial glia-type stem cells and neural crest progenitors derived thereof. The data provided reveal that pNBSCs can be directed into defined neural cell types of the CNS- and neural crest lineage.

The data provided reveal that (i)NBSCs can be directed into defined neural lineages and that iNBSCs pass through successive developmental stages. These data support the notion that it is possible to reprogram human adult cells into expandable, multipotent NBSCs that define a novel embryonic neural stem cell population in human and mouse.

Here we provide single cell RNA-sequencing data of six iNBSC lines (310 cells total). iNBSCs were single-cell-sorted and RNA sequencing was performed following the Smart-seq2 protocol. This dataset further supports the notion that iNBSC cultures mainly consist of stem cells with a molecular and functional neural plate border-like identity and a minor fraction of cells that show signs of some spontaneous differentiation towards sensory neurons.
