Summary

Direct reprogramming offers a powerful approach to generate therapeutic cell types, but progress is limited by an incomplete understanding of transcription factor (TF) cooperativity. Here, we present a protocol for performing combinatorial TF screening to resolve reprogramming factor networks that drive cell identity. We describe steps for arrayed lentiviral production, transduction, and reprogramming of human fibroblasts into distinct immune cells. We detail procedures for cell purification, library preparation, sequencing, and analysis to resolve TF combinations and dynamics.
