Absolute Scaling of Single-Cell Transcriptomes Reveals Pervasive Hypertranscription in Adult Stem and Progenitor Cells
Introduction Single cell RNA-seq (scRNA-seq) is a powerful tool to measure gene expression in individual cells. While relative gene expression differences are currently analyzed with great interest in single cell data, differences in total transcript levels were mainly considered technical artefacts and removed during normalization, assuming that single cells contain…
Frontiers | Hair Graying Regulators Beyond Hair Follicle
Introduction Hair graying is one of the representative signs of aging. It has been considered to be triggered by a decreased number of follicular melanocyte stem cells (MeSCs; Nishimura et al., 2005; Iida et al., 2020) or dysfunction of MeSCs such as decreased oxidation resistance capacity with aging (Shi et…
From mESCs to mEPSCs: A proteomics-based study
Out laboratory has derived mEPSCs from mESCs, which represents a breakthrough in stem cell research. Unlike the standard pluripotent stem cells, mEPSCs can contribute to both embryonic and extra-embryonic lineages in the chimera assay (Yang et al., 2017a). In the development of EPSC culture conditions, many small molecules are tested…

p57 Suppresses the Pluripotency and Proliferation of Mouse Embryonic Stem Cells by Positively Regulating p53 Activation
Embryonic stem cells (ESCs) are pluripotent stem cells that have indefinite self-renewal capacities under appropriate culture conditions in vitro. The pluripotency maintenance and proliferation of these cells are delicately governed by the concert effect of a complex transcriptional regulatory network. Herein, we discovered that p57Kip2 (p57), a cyclin-dependent kinase inhibitor…
