Simona and Luiza will present some work progress on different projects running in the lab at the Bergen Stem Cell Consortium Research Seminar on Friday, 12th of April 2019 at Glasblokkene

Cell-identity switches, in which terminally differentiated cells are converted into different cell types when stressed, represent a widespread regenerative strategy in animals, yet they are poorly documented in mammals. In mice, some glucagon-producing pancreatic α-cells and somatostatin-producing δ-cells become insulin-expressing…

One temporary short-term position is now available! The project aims to develop and employ (i) an innovative in vivo system allowing the differentiation, monitoring, retrieval, characterization and modulation of MODY-iPSC-derived β-cells; (ii) methods for characterizing the cellular processes and molecular…
The mechanisms that restrict regeneration and maintain cell identity following injury are poorly characterized in higher vertebrates. Following β-cell loss, 1-2% of the glucagon-producing α-cells spontaneously engage in insulin production in mice. Here we explore the mechanisms inhibiting α-cell plasticity.…

Chakravarthy et al. dissect the mechanisms maintaining α cell identity and reveal that simultaneous inactivation of the DNA methyltransferase Dnmt1 and the transcription factor Arx in adult mice drives the conversion of α- to β-like cells. In human T1D islets, glucagon+ cells lose DNMT1 and ARX expression and express β cell markers.
