Third, while bulk proteomics provides a comprehensive view of cellular differentiation pattern, more precise methods such as single-cell technologies (transcriptomics or proteomics) 38,39 and spatiotemporal single-cell tracking 40,41 would further elucidate the detailed cellular composition and 3D organization during iHLO development

Troubleshoot aggregation and precipitation early, and verify concentration with lab methods when accuracy counts
