         <p>With the <a target=_blank href="https://cells.ucsc.edu">Cell Browser</a>
         you can plot cells arranged by algorithms like t-SNE or UMAP. Color
         these by annotated meta data or genes via the left side bar. Select
         cells via the legend on the right or with the rectangle selection tool.
         You can export the current cell selection or annotate it via the "Tools" menu.

 Below is a screenshot of a  
 <a target="_blank" 
 href="http://genome.ucsc.edu/s/Max/tabMuris">public session</a>
 that highlights the Tabula Muris gene expression track
 The session shows the Sox10 locus. The gene expression track at the top shows that the
 gene is only well expressed in basal cells (orange), mammary gland (blue) and oligodendrocytes (pink).
 These cell type names are shown when you hover with the mouse over the bars on
 the genome browser. The coverage tracks below show that all exons are
 transcribed in these, but the last exon is also transcribed in stromal cells
 and some non-coding transcription is seen in goblet cells 3' of the gene. The
 splicing tracks below show that proper splicing is limited to the four cell types
 described above. This is also a non-coding region conserved in zebrafish and chicken.
