Dual-smad inhibition

WebDec 6, 2024 · The combination of these 2 SMAD signaling inhibitory factors eliminates the need for an intermediate process, such as EB formation or co-culturing with a stromal feeder, and simplifies the neural induction protocol. TABLE 1 Table 1. Neural differentiation approaches in 2D and 3D using stem cells. 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 ).
