Challenges: Scalability, Cost, and Data Management
High-throughput transcriptomics has become foundational for functional genomics, drug discovery, and precision medicine. However, as the field rapidly moves into 2025 and beyond, several challenges persist—particularly regarding scalability, cost, and data management.
Scalability remains a central concern. Techniques such as single-cell RNA sequencing (scRNA-seq) and spatial transcriptomics are now capable of profiling tens to hundreds of thousands of cells per experiment. Leading platforms, such as 10x Genomics Chromium and NanoString Technologies CosMx, have introduced automation and parallelization to increase throughput. Still, scaling sample preparation, library construction, and sequencing while maintaining data quality is a bottleneck, especially for large population-based studies or multi-site collaborations. The complexity of integrating these workflows in clinical or industrial environments introduces additional hurdles as demand for large-scale and multi-omic studies grows.
Cost is closely tied to scalability. While the cost per datapoint has decreased substantially over the past decade, comprehensive experiments remain expensive. As of 2025, the price of reagents, consumables, sequencing, and cloud-based analytics is still a limiting factor for widespread adoption, particularly in resource-limited settings. Companies like Illumina and Pacific Biosciences are actively working on reducing sequencing costs through improved chemistry and higher-throughput instruments.
