Single Cell Targeted Sequencing

Single cell targeted sequencing (scTS) is designed to enable high-resolution analysis of specific genomic regions within individual cells. This approach offers distinct advantages for extracting detailed genetic information from complex biological samples. Traditional genomic sequencing methods typically require large numbers of cells, yielding population-averaged results that obscure cell-to-cell variability. In contrast, single cell targeted sequencing provides genome-level insights at single-cell resolution, uncovering cellular heterogeneity and enhancing our understanding of individual cell functions and states.

 

Single cell targeted sequencing has been widely applied across diverse research domains. In oncology, tumor cells often harbor distinct genetic mutations and expression profiles; scTS enables the detection and characterization of intratumoral heterogeneity, thereby informing the development of personalized therapeutic strategies. In immunology, this technique allows for the dissection of individual immune cell genomes, revealing their functional roles in disease contexts. For instance, in autoimmune disease research, scTS can identify key immune cell subsets and their activation states, offering mechanistic insights into disease pathogenesis. Stem cell research also benefits from scTS, as it facilitates the identification of cells at different stages of differentiation, thus contributing to advancements in regenerative medicine and cell-based therapies. In the realm of drug discovery, single cell analysis helps pinpoint and characterize drug targets with high precision, improving drug design and efficacy. Moreover, scTS supports gene therapy research by identifying disease-causing mutations at the single-cell level, providing precise targets for genome editing interventions.

 

The technical workflow of single cell targeted sequencing involves several critical steps: cell isolation, whole-genome amplification, targeted capture, and high-throughput sequencing. The process begins with isolating individual cells from heterogeneous samples using microfluidic platforms or laser capture microdissection. Next, whole-genome amplification is employed to increase the amount of genomic DNA from single cells, ensuring sufficient sensitivity and accuracy in downstream analyses. During the targeted capture phase, genomic regions of interest are selectively enriched using capture probes or CRISPR-based methods. Finally, these enriched regions are sequenced using high-throughput technologies to generate high-fidelity genomic data.

 

Despite its powerful capabilities, single cell targeted sequencing presents technical and analytical challenges. The minute starting material of single cells introduces the risk of bias during amplification and capture, such as unequal amplification efficiency and over- or under-representation of specific sequences, potentially distorting the data. To address these issues, robust algorithms and analytical tools are required to correct for such biases and ensure data reliability. Additionally, the sheer volume and complexity of single cell data can overwhelm conventional bioinformatics pipelines, necessitating advanced computational strategies and high-performance infrastructure for accurate interpretation.
