Fig. 4: Spatial transcriptomics to map uTAR expression in chicken embryonic hearts.

a Spatial log-e-normalized expression of canonical TNNT2 myocytes marker, SH3BGR uTAR, canonical COL1A1 epicardial cells marker, RUNX1T1 uTAR, and annotated RUNX1T1 gene for chicken embryonic heart at day 4 (5 hearts) and day 14 (1 heart) post fertilization. b Dendrogram computed on Pearson correlation of log-e-normalized spatial expression for canonical gene markers and uTARs (underlined) in a day 4 chicken heart tissue section.
