Genetic chimeras reveal that Uhrf1 functions cell-non-autonomously and cell-autonomously in ENS development. (A) Transplantation experiment diagram. Wildtype or uhrf1 mutant donor embryos that carry the phox2b:EGFP transgene were injected with rhodamine dextran. Vagal neural crest cells were transplanted from donors into unlabeled wildtype or uhrf1 mutant hosts. The contribution of transplanted cells was evaluated at 5 dpf. (B) Possible results for transplantation experiments to test cell-non-autonomous function of uhrf1 in ENS development. (C) Possible results for transplantation experiments to test cell-autonomous function of uhrf1 in ENS development. (D) phox2b:EGFP positive (green) wildtype cells transplanted into wildtype hosts can populate the entire intestine. Note that the density of these cells is less than in non-transplanted animals because they share the territory with unlabeled ENS cells of the host. (E) phox2b:EGFP positive (green) wildtype cells transplanted into uhrf1 mutant hosts can expand, but are consistently excluded from distal intestine (outlined and labeled with asterisk). (F) phox2b:EGFP positive (green) uhrf1 mutant cells transplanted into wildtype hosts can migrate to distal intestine in rare cases (1/5), but the population of transplanted mutant cells that successfully integrate into the ENS is smaller than that of the wildtype host cells as revealed by Elavl staining (magenta).
