Description
This track displays single-cell data from 12 papers covering 14 organs. Cells are grouped
together by organ and cell type. The cell types are based on annotations published alongside
the papers. These were curated at UCSC as much as possible to use the same cell type
terminologies across papers and organs. In some cases, we merged together small populations
of cells annotated as distinct and related types into a single type so as to have enough cells
to call gene expression levels accurate.
The gene expression levels are normalized so that the total level of expression for all genes in a
single cell or cell type adds up to one million.
Display Conventions and Configuration
The cell types are colored by which class they belong to according to the following table.
Please note, the coloring algorithm allows cells that show some mixed characteristics to =
show blended colors so there will be some color variation within a class. In addition,
cells with less than 100 transcripts will be a lighter shade and less
concentrated in color to represent a low number of transcripts.

All components were normalized to be in parts per million using the
matrixNormalize command available from UCSC. Metadata was cleaned up using the
tabToTabDir tool. The major clean-ups were unpacking abbreviations, replacing
jargon with standard English, choosing shorted terms to shorten long labels,
labeling outliers, etc. Before integration we invited the original data
producers as well as local biologists and informaticions to view the
data.
Credits
Many thanks to the data contributing labs for sharing their high quality research.
Thanks to the Cell Browser team including Matt Speir and Max Haeussler, for their work
in integratinging these datasets into the Cell Browser. In most cases, their efforts were
ahead of our own and we could leverage their work making the job much easier. Within the
Genome Browser group, Jim Kent did the initial wrangling, and Brittney Wick did substantial data
cleanup and coordination with the labs.
