Sparse labeling of iMOP-derived neurons for pseudotemporal ordering. (A) Nuclear labeling with Hoechst and immunostaining of iMOP-derived neuron with antibodies against CDKN1B and TUBB3. (B) Expression of GFP in TUBB3 marked cells by transfecting a GFP overexpression plasmid for sparse labeling and neurite tracing. Arrowheads mark the path of the neurite in a single neuron. (C) Workflow to identify GFP+ TUBB3– and GFP+ TUBB3+ cells for fluoresence intensity and neurite length measurements. (D) Arrangement of iMOP-derived neurons based on TUBB3 labeling and neurite lengths to generate a pseudotemporal ordering of cells that represent a differentiation trajectory. Scale bars as noted.
