+<h2>Apr. 15, 2022 &nbsp;&nbsp; Merged Cell Expression on hg38</h2>
+<p>
+The Genome Browser already provided <a href="#111721">single-cell RNA-seq datasets</a> for the
+human GRCh38/hg38 assembly, but those data have so far been split among a collection of tracks
+depending on the organ and publication source.  We are happy to announce that data from 12 of
+those papers (and 14 organs) are now available in a combined
+<a href="../cgi-bin/hgTrackUi?db=hg38&g=singleCellMerged">Merged Cells</a> track that provides
+normalized RNA-seq values for every cell type in those sets.  All components were normalized
+to show expression in parts per million.</p>

 <h2>Apr. 12, 2022 &nbsp;&nbsp; T2T CHM13 v2.0 now available in the Genome Browser</h2>
 <p>
 The Genome Browser has a <a href="/goldenPath/history.html">rich history</a> intricately connected
 to human genomic research. We have provided display to almost two dozen human genomes beginning 
 with the first drafts in the year 2000. Nearly 22 years later, the <a 
 href="https://sites.google.com/ucsc.edu/t2tworkinggroup" target="_blank">T2T consortium</a> has 
 published the most complete human haploid genome sequence to date, having added just about all of the 200 
 million bases (8%) missing from the current reference. We are proud of all the scientists 
 involved, including our colleagues in the <a href="https://genomics.ucsc.edu/" 
 target="_blank">UCSC Genomics Institute</a>, who played a role in this release. We strive
 to facilitate omics research and thus would like to announce our expanded support for 
 the <a 
 href="/cgi-bin/hgTracks?hubUrl=https://hgdownload.soe.ucsc.edu/hubs/GCA/009/914/755/GCA_009914755.4/hub.txt&genome=GCA_009914755.4&position=lastDbPos"
