OTX2 impedes self–renewal of porcine iPS cells through downregulation of NANOG expression
The transcription factor Otx2 acts as a negative switch in the regulation of transition from naive to primed pluripotency in mouse pluripotent stem cells. However, the molecular features and function of porcine OTX2 have not been well elucidated in porcine-induced pluripotent stem cells (piPSCs). By studying high-throughput transcriptome sequencing and interfering endogenous OTX2 expression, we...
متن کاملEnhanced self-renewal of hematopoietic stem/progenitor cells mediated by the stem cell gene Sall4
BACKGROUND Sall4 is a key factor for the maintenance of pluripotency and self-renewal of embryonic stem cells (ESCs). Our previous studies have shown that Sall4 is a robust stimulator for human hematopoietic stem and progenitor cell (HSC/HPC) expansion. The purpose of the current study is to further evaluate how Sall4 may affect HSC/HPC activities in a murine system. METHODS Lentiviral vector...
متن کاملSelf-Renewal of Stem Cells
Asymmetric division is one of the most fundamental characteristics of adult stem cells , which ensures one daughter cell maintains stem cell status and the other daughter cell becomes committed to differentiation. New data emerged recently that allow us to conclude that asymmetric division has another important aspect: it enables self-maintenance of stem cells.
متن کاملNucleostemin maintains self-renewal of embryonic stem cells and promotes reprogramming of somatic cells to pluripotency
Nucleostemin (NS) is a nucleolar GTP-binding protein that was first identified in neural stem cells, the functions of which remain poorly understood. Here, we report that NS is required for mouse embryogenesis to reach blastulation, maintenance of embryonic stem cell (ESC) self-renewal, and mammary epithelial cell (MEC) reprogramming to induced pluripotent stem (iPS) cells. Ectopic NS also coop...
متن کاملMAPKAP kinase MK2 maintains self-renewal capacity of haematopoietic stem cells.
The structurally related MAPK-activated protein kinases (MAPKAPKs or MKs) MK2, MK3 and MK5 are involved in multiple cellular functions, including cell-cycle control and cellular differentiation. Here, we show that after deregulation of cell-cycle progression, haematopoietic stem cells (HSCs) in MK2-deficient mice are reduced in number and show an impaired ability for competitive repopulation in...
