In Vitro Pancreas Organogenesis from Dispersed Mouse Embryonic Progenitors

Filippo De Franceschi, Anne Grapin-Botton, Chiara Greggio

The pancreas is an essential organ that regulates glucose homeostasis and secretes digestive enzymes. Research on pancreas embryogenesis has led to the development of protocols to produce pancreatic cells from stem cells. The whole embryonic organ can be c ...

Artificial three-dimensional niches deconstruct pancreas development in vitro

Matthias Lütolf, Filippo De Franceschi, Anne Grapin-Botton, Adrian Ranga, Samy Gobaa, Chiara Greggio

In the context of a cellular therapy for diabetes, methods for pancreatic progenitor expansion and subsequent differentiation into insulin-producing beta cells would be extremely valuable. Here we establish three-dimensional culture conditions in Matrigel ...

A Notch-dependent molecular circuitry initiates pancreatic endocrine and ductal cell differentiation

Anne Grapin-Botton

In the pancreas, Notch signaling is thought to prevent cell differentiation, thereby maintaining progenitors in an undifferentiated state. Here, we show that Notch renders progenitors competent to differentiate into ductal and endocrine cells by inducing a ...

RNA Profiling and Chromatin Immunoprecipitation-Sequencing Reveal that PTF1a Stabilizes Pancreas Progenitor Identity via the Control of MNX1/HLXB9 and a Network of Other Transcription Factors

Emilie Gesina, Philipp Bucher, Anne Grapin-Botton, Nancy Thompson

Pancreas development is initiated by the specification and expansion of a small group of endodermal cells. Several transcription factors are crucial for progenitor maintenance and expansion, but their interactions and the downstream targets mediating their ...

Planar Cell Polarity Controls Pancreatic Beta Cell Differentiation and Glucose Homeostasis

Anne Grapin-Botton, Mathieu Gouzi, Cédric Cortijo

Planar cell polarity (PCP) refers to the collective orientation of cells within the epithelial plane. We show that progenitor cells forming the ducts of the embryonic pancreas express PCP proteins and exhibit an active PCP pathway. Planar polarity proteins ...

Neurogenin3 Initiates Stepwise Delamination of Differentiating Endocrine Cells During Pancreas Development

Anne Grapin-Botton, Mathieu Gouzi, Yung Hae Kim, Keiichi Katsumoto

During development, pancreatic endocrine cells are specified within the pancreatic epithelium. They subsequently delaminate out of the epithelium and cluster in the mesenchyme to form the islets of Langerhans. Neurogenin3 (Ngn3) is a transcription factor r ...

Definition of in Vitro Microenvironments to Characterize and Control Pancreatic Progenitor Expansion and Differentiation

Chiara Greggio

The pancreas plays a central role in metabolism. The exocrine pancreas, composed of ductal and acinar cells, secretes and delivers digestive enzymes into the duodenum where they contribute to food digestion. The endocrine pancreas, constituted by the islet ...

Role of Neurogenin3 in migration of pancreatic endocrine cells during development

Mathieu Gouzi

The pancreas is one of the major organs of the digestive tract. Its endocrine function, mainly regulating glucose blood level, is achieved by endocrine cells. These cells are organized in clusters, the so-called islets of Langerhans. During development, th ...

Wnt Signaling in Pancreas Development and Cancer

Marine Marie Kraus

During early somite stages of development, the broad endoderm-derived foregut and hindgut territories become further subdivided along the antero-posterior axis into organs. One of these organs is the pancreas which serves two major physiological functions: ...
