Figure 6From: Stimulation of Activin A/Nodal signaling is insufficient to induce definitive endoderm formation of cord blood-derived unrestricted somatic stem cellsRepresentative micrographs of IDE1/2-treated USSC. USSC grown in SCPM (A, B), RPMI (C, D), or RPMI containing 100 nM IDE1 (E, F) or 200 nM IDE2 (G) (100×). A proportion of USSC treated with IDE1/2 developed a rounded morphology (E, F, G).Back to article page
