Single‐Cell Profiling: Any Scale, Any Size, All at Once

Single‐cell technologies have revolutionized the understanding of cellular heterogeneity, revealing distinct cell populations and functional states with molecular precision. Traditional approaches, however, are constrained by cellular dimension and throughput scale, in addition to its inability preserve spatial information. Recent innovations now allow high throughput, large‐sized cell, and multi‐modal profiling of patient samples, overcoming these limitations. In this perspective, three recently developed single‐cell technologies is described, highlighting how their enhanced throughput, resolution, and sensitivity provide deeper insights into cellular identity and function.
