**Figure 2 - Inhibition of Inferred Regulatory Kinases impairs PMA induced differentiation of hESC.**
**A** Representative images of differentiation marker MAPK (pT202/Y204) expression in hES cells stimulated with PMA. Scale bar: 30\(\mu\)m.
**B** Time course quantification of MAPK activation levels after PMA stimulation in the presence or absence of MAPK inhibitor (PD184352).
**C** Relative changes in kinase activities using Kinase Set Enrichment Analysis (KSEA) benchmarked against antibody-measured reporter phosphosites in the intervals 0-30 and 0-60 minutes.
