Figure 9

Activin receptor (ACVR) protein levels. Representative light micrographs (400×) depicting the localization of ACVR (brown staining) in USSC grown in SCPM. Nuclei are counterstained blue with Haematoxylin. USSC 1 (left column) and USSC 2 (right column) expressed ACVR1b (A, B), ACVR2a (C, D) and ACVR2b (E, F). No staining was detected in the IgG controls (G, H).
