Dual smad ds inhibition
WebJul 1, 2024 · Neuronal differentiation protocols such as dual-SMAD inhibition have been used since the discovery of hiPSC technology (Chambers et al., 2009 ). However, yield and cell type is highly variable and the number and proportion of excitatory versus inhibitory neurons changes over batches and across genetic backgrounds ( Micali, 2024 ). WebBased on conserved developmental principles, we have developed a simple but highly efficient platform to convert human PSCs into neural tissue. We have shown that dual-SMAD inhibition via small molecule inhibitors of BMP and TGFb/Activin/Nodal signaling is sufficient to trigger neural conversion.
