TGF-β signaling controls neural crest developmental plasticity via SMAD2/3 [ATAC-seq]

Project description:The neural crest is a highly plastic stem cell population that represents a notable exception to the germ layer theory. Despite being of ectodermal origin, these cells can differentiate into skeletal derivatives like cartilage and bone, tissues that are typically formed by mesoderm. The inductive program that endows the neural crest with these unique properties is still poorly understood. Here, we report that Smad2/3-mediated TGFβ signaling endows cranial neural crest cells with enhanced developmental potential. Our results show that TGFβ signaling modulates neural crest axial identity and directly activates the gene circuits that support skeletal differentiation. Cooperation between TGFβ and low levels of WNT-signaling in the embryonic head activates cranial-specific cis-regulatory elements of anterior genes. Activation of the TGFβ pathway allowed reprogramming of trunk neural crest cells to adopt an anterior identity and led to the development of an improved protocol for the generation of human cranial neural crest cells. Our findings indicate TGFβ signaling is required for the specification of cranial neural crest cells, endowing them with the potential to give rise to the craniofacial skeleton.

The phosphorylation of the Smad2/3 linker region by Nemo-like kinase regulates TGF-β signaling

Project description:Smad2 and Smad3 (Smad2/3) primarily mediates the transforming growth factor-β (TGF-β) signaling that drives cell proliferation, differentiation, and migration. The dynamics of the Smad2/3 phosphorylation provides the key mechanism for regulating the TGF-β signaling pathway. Here we identified NLK as a novel regulator of TGF-β signaling pathway via modulating the phosphorylation of Smad2/3 in the linker region.
