WebOct 21, 2024 · Pdx1, a master regulator of the pancreatic program, is responsible for initiation of pancreatogenesis and is strongly expressed by all MPCs. Sox9 is crucial to maintaining the MPC niche and its role was identified through the observation of pancreatic hypoplasia in Sox9 null mice 4 and lineage‐tracing studies 5. WebAfelik, S. (2006). Combined ectopic expression of Pdx1 and Ptf1a/p48 results in the stable conversion of posterior endoderm into endocrine and exocrine pancreatic tissue.
WebConsistent with the proposal that Ptf1a supports the specification of precursors of all three pancreatic cell types, transgene-based expression of Pdx1, a gene essential to pancreas formation, from Ptf1a cis-regulatory sequences restores pancreas tissue to Pdx1-null mice that otherwise lack mature exocrine and endocrine cells because of an early … WebPdx1 and Ptf1a transcription factors control early steps of pancreas specification. a Wholemount immunofluorescence for Pdx1 in an E10.5 mouse embryo revealing the …
