Methodological protocol demonstrates single-cell clonal selection in human pluripotent stem cells, highlighting a survival rate over 50% without cell sorting.
Single-cell clonal selection is a critical procedure for generating a homogeneous population of human pluripotent stem cells. Here, we present a protocol that repurposes the STRIPPER Micropipetter, normally used for in vitro fertilization, to pick single stem cells. We describe steps for tool and reagent preparation, single-cell picking, and colony passaging. We then detail procedures for amplification and analysis. Our protocol does not require cell sorting and produces homogenous clonal cultures with more than 50% survival rate. For complete details on the use and execution of this protocol, please refer to Deng et al.1
