Single-cell sequencing technologies have brought up an unprecedented level of resolution to omics studies with extremely detailed views into individual cells’ expression patterns. With the emergence of drop-based sequencing methods, the resolution now even comes with scale and efficiency. In a single experiment, scientists can now profile hundreds of thousands of cells, or even 2 million cells at a time (Cao et. al., 2019), and generate a huge amount of single-cell data, providing valuable inputs for biological research and breakthroughs.
However, huge amounts of single-cell data generated are posing major challenges for hosting, accessing, visualization and analysis. Although multiple repositories are available (eg.: Gene Expression Omnibus by NCBI, EBI, Human Cell Atlas, etc.), single-cell sequencing datasets are currently provided in different formats. Given the increasing size of the data, it is extremely challenging to explore many single-cell datasets at a time because of such variability in formats, and expensive computational resources to process. We are lucky to have some nice visualization portals at hand, thanks to the authors of the data, yet these portals are separate from one another, making it uneasy to combine multiple single-cell datasets for meta-analysis.
To address the challenges, we developed a single-cell data portal and standardized analytics dashboard in BioTuring Single-cell Browser, enabling any biologists to easily access, reanalyze, combine, and discover valuable stories from published single-cell datasets on their laptop.

3D UMAP of 1.3 million cells from the mouse organogenesis cell atlas (MOCA) (Cao et al., 2019) in BioTuring Single-cell Browser
A curated database of more than 4 million cells, ready for downstream analyses
Our curated database in BioTuring Single-cell Browser is currently hosting more than 4 million cells from 12 different tissues and more than 60 latest high-impact single-cell studies, including the mouse organogenesis cell atlas by Cao and colleagues (2019), mouse retinal cell atlas (Clark et al., 2019) and the liver cell atlas (MacParland et al., 2018). The datasets are increasing exponentially in number, all ready for exploring in a few clicks, with interactive visualizations, and state-of-the-art analytics.
