Figure 2. Novel Developmental Growth Stage Identified by Genomics.

Figure 2

In this figure from Kho et al., the transcriptome profile of the 38-sample developing human fetal lung time series is show in the first two principal components . While age correlates well with PC1, inflection points in PC2 indicate a novel molecular transition at day 94, which is independent of histologic stage.(13)
