Julian Gough uses theoretical and computational approaches to harness the power of data generated by experimental methods to advance scientific knowledge in areas including regenerative medicine and personal genomics. The transcriptome is the set of all RNA molecules in a specified cell population. This image for day 153 of #LMB365 shows a map derived from real human cellular transcriptome data. Hundreds of cell types are plotted on the landscape and a few of them highlighted with labels.
