Traditional differentiation protocols use embryoid body (EB) formation as the first step of lineage restriction to mimic early human embryogenesis, which is then followed by manual selection of neuroepithelial precursors. This procedure is tedious and often inconsistent. We have developed a novel neural differentiation scheme that directs human iPSCs (created with the Allele 6F mRNA reprogramming kit) that progressed, as attached culture, to neural precursor cells (NPCs) in just 4-6 days, half the time it typically takes by other methods. From NPCs it takes about another 5-6 days for neural rosettes to form (see figures below); upon passage, cells in neural rosettes differentiate into neurons in 24 hours.

The neural progenitors at the rosettes stage can be stocked and expanded, before differentiated into different types of neurons. We are working on specifically and efficiently different these neural progenitor cells into dopaminergic, glutamatergic, GABAergic, and other types of sub-types of neurons with Allele’s technologies (Questions? email the Allele Stem Cell Group at iPSatAllelebiotech.com).

Neural rosettes formed efficiently in wells without going through EB.
