Mission Bio, Inc., a pioneer in high-throughput single-cell DNA and multi-omics research, announced the commercial availability of the Tapestri Solution for Solid Tumor Research. On the Tapestri Platform, this new end-to-end single-cell DNA sequencing process comprises a nuclei isolation prep technique, pre-designed research panels for breast cancer and glioblastoma multiforme, and an enhanced single-cell copy number variation (CNV) bioinformatic analysis tool. Mission Bio currently covers solid tumors in addition to hematologic malignancies, where Tapestri is widely used to study tumor heterogeneity and gain new insights into the clonal variety and architecture driving disease progression, biomarkers, and therapeutic management.
Recent high-profile research studies utilizing custom Tapestri assays for breast cancer, non-small cell lung cancer, colorectal cancer, and melanoma have demonstrated the utility of high-resolution tools for assessing solid tumor heterogeneity and clonal evolution, which contribute to disease onset, progression, and relapse. However, bulk next-generation sequencing technologies cannot offer the cell-by-cell mutational data required to detect disease-causing biological drivers — they are confined to population-level average metrics and lack information on clonal diversity.
Tapestri quantifies DNA mutations at the individual cell level in thousands of cells simultaneously, simultaneously detecting SNVs, indels, and CNVs, conclusively identifying variant zygosity and mutational co-occurrence recognizing unusual cell populations. As a result, researchers studying solid tumors may now make use of a comprehensive workflow designed for the Tapestri Platform, which includes the following:
Sample preparation assistance with an enhanced nuclei isolation process for both fresh and frozen samples
New study panels for breast cancer and glioblastoma were meticulously selected to contain hotspot genes, copy number variants, and chromosomal arm aneuploidies linked with each illness. Additionally, users may create custom panels that target specific human or mouse genome regions.
Enhanced capacity for CNV bioinformatics analysis with the development of a new visualization tool (in collaboration with Mission Bio's Field Application Scientist team).
This integrated workflow approach has the potential to significantly advance our knowledge of disease progression and enable the development of more specific medicines.
The commercial introduction of Mission Bio's Tapestri Solution for Solid Tumor Research demonstrates the company's ongoing commitment to allowing more precise cancer research using single-cell DNA sequencing. In addition, mission Bio has announced the establishment of its first Center of Excellence for solid tumor single-cell DNA profiling at Memorial Sloan Kettering Cancer Center (MSKCC).
The impressive results already seen from our early work with solid tumor researchers helped guide the development of these new workflows and underscored our commitment to providing unique and indispensable tools for solid tumor researchers. Just as Tapestri has been an invaluable tool for hematologic malignancy researchers, we're confident that our research panel pair, new prep protocol, and improved bioinformatics analysis capabilities will demonstrate the platform's value in solid tumors."
CEO of Mission Bio, Yan Zhang, Ph.D., said.
