Project description:While the regulatory landscape during stem cell differentiation has been well characterized, the shared and unique regulatory mechanisms in different ectodermally-derived epithelial cells have not been well described. Through defining the complement of super enhancers and typical enhancers in corneal epithelium for the first time, we show that regulatory regions are often shared between cell types of the same lineage, and that corneal super enhancers are already marked as potential regulatory domains in embryonic stem cells. Through the enrichment of KLF motifs in enhancers, we identified and defined a novel role for Kruppel family member KLF7 in promoting the corneal progenitor cell state, in many cases working antagonistically to corneal differentiation promoting KLF4. Our work highlights the importance of balance between proliferation and differentiation, both for proper tissue development and for homeostasis.

Project description:Analysis of change in transcriptosome after KLF4, KLF9, KLF11, KLF16 and KLF17 knockdown in hADSC. Analysis of effects of siRNA transfection (siCtrl, siKLF4, siKLF9, siKLF11, siKLF16 and siKLF17) in hADSC at gene expression level.The hypothesis tested in the present study was that different KLF members have distinctive roles in these cells.

Project description:This experiment is part of the FunGenES project (FunGenES - Functional Genomics in Embryonic Stem Cells partially funded by the 6th Framework Programme of the European Union, http://www.fungenes.org). The experiment was conducted at Inserm U846, Bron, France. Aim: Kru_ppel-like factors (Klf) 4 and 5 are two closely related members of the Klf family, known to play key roles in somatic cell reprogramming and in self-renewal of pluripotent stem cells. In this study, we focused on the functional divergence between Klf4 and Klf5. We showed that Klf4 and Klf5 regulate the expression of distinct subsets of genes. Klf4 negatively regulates the expression of endodermal markers, some of which encode transcription factors involved in the commitment of pluripotent system cells to endoderm differentiation. In contrast, Klf5 negatively regulates the expression of mesodermal markers, some of which controls commitment to the mesoderm lineage. Functional studies with reporter cell lines indicate that knockdown of Klf4 enhances differentiation toward visceral endoderm, mesendoderm, and definitive endoderm, whereas knockdown of Klf5 specifically enhances differentiation toward mesoderm. Thus, additive functions of Klf4 and Klf5 secure pluripotent stem cell propagation by inhibiting endoderm and mesoderm differentiation.
