Multiplexed multi-modal single cell technologies: From observation to perturbation analysis.

Abstract

Single cell technologies have undergone significant transformation, expanding from their initial focus on transcriptomics to encompass a diverse range of modalities. Recent advancements have markedly improved scalability and reduced costs, facilitating the processing of larger cell populations and broadening the scope of single cell research. The incorporation of CRISPR-based perturbations has revolutionized the field by enabling precise functional genomics and detailed studies of gene regulation at the single cell level. Despite these advancements, challenges persist, particularly in achieving genome-wide perturbations and managing the complexity of high-throughput data. This review discusses the technological milestones that have driven these changes, the current limitations of single cell CRISPR technologies, and the future directions needed to address these challenges and advance our understanding of cellular biology.
