Mitchell-Riley syndrome iPSCs exhibit reduced pancreatic endoderm differentiation due to a mutation in .

Mitchell-Riley syndrome (MRS) is caused by recessive mutations in the regulatory factor X6 gene () and is characterised by pancreatic hypoplasia and neonatal diabetes. To determine why individuals with MRS specifically lack pancreatic endocrine cells, we micro-CT imaged a 12-week-old foetus homozygous for the nonsense mutation c.1129C>T, which revealed loss of the pancreas body and tail.

Xenopus laevis FGF16 activates the expression of genes coding for the transcription factors Sp5 and Sp5l.

Fibroblast growth factors (FGFs) comprise a family of signalling molecules with essential roles in early embryonic development across animal species. The role of FGFs in mesoderm formation and patterning in Xenopus has been particularly well studied. However, little is known about FGF16 in Xenopus.
