Examination of the role of BMP signaling in patterning of human pluripotent stem cell derived mid/hindgut spheroids and maintenance of this patterning in organoids transplanted under mouse kidney capsules.


ABSTRACT: The goal of this study was to test the hypothesis that BMP signaling regulates patterning of human CDX2+ gut tube cultures (Spence et al 2011, Watson et al. 2014). The study is comprised of 2 separate experiments. The first experiment was to determine the immediate impact of BMP signaling on CDX2+ gut tube cultures. To do so we tested spheroids, spheroids after plating in Matrigel and exposed to 3 days of Noggin (100ng/mL), spheroids after plating in Matrigel and exposed to 3 days of EGF alone (100ng/mL, Control), and spheroids after plating in Matrigel and exposed to 3 days of BMP2 (100ng/mL). RNA was collected from spheroids and spheroids after 3 days of patterning. The second experiment examined if patterning was maintained after this initial 3 days of patterning and an addition 8-10 weeks following transplantation in vivo. To do this we grew all Matrigel plated spheroids for an additional 25 days in media containing EGF alone (Control media). We then transplanted these organoids under the mouse kidney capsule and allowed them to mature for 8-10 weeks. We then collected RNA from the transplanted organoids.
