NuMA regulates mitotic spindle assembly, structural dynamics and function via phase separation

Nature Communications, 2021
Mitotic spindle assembly is required for proper cell division, but many underlying mechanisms remain unclear. Here, the authors show that NuMa undergoes liquid-liquid phase separation, condensing on spindle poles during mitotic entry and enriching ...

In Vitro Modeling of Blood-Brain Barrier with Human iPSC-Derived Endothelial Cells, Pericytes, Neurons, and Astrocytes via Notch Signaling

Stem Cell Reports, 2017
The blood-brain barrier (BBB) is composed of four cell populations, brain endothelial cells (BECs), pericytes, neurons, and astrocytes. Its role is to precisely regulate the microenvironment of the brain through selective substance crossing.

Using single-cell entropy to describe the dynamics of reprogramming and differentiation of induced pluripotent stem cells [PDF]

, 2020
Induced pluripotent stem cells (iPSCs) provide a great model to study the process of reprogramming and differentiation of stem cells. Single-cell RNA sequencing (scRNA-seq) enables us to investigate the reprogramming process at single-cell level. Here, we introduce single-cell entropy (scEntropy) as a macroscopic variable to quantify the cellular ...

TOX is a critical regulator of tumour-specific T cell differentiation

Nature, 2019
Tumour-specific CD8 T cell dysfunction is a differentiation state that is distinct from the functional effector or memory T cell states1–6. Here we identify the nuclear factor TOX as a crucial regulator of the differentiation of tumour-specific T (TST ...

Genome and epigenome analysis of monozygotic twins discordant for congenital heart disease

BMC Genomics, 2018
Background Congenital heart disease (CHD) is the leading non-infectious cause of death in infants. Monozygotic (MZ) twins share nearly all of their genetic variants before and after birth.

Role of PDLIM1 in hepatic stellate cell activation and liver fibrosis progression

Scientific Reports, 2023
Liver fibrosis is caused by chronic hepatic injury and may lead to cirrhosis, and even hepatocellular carcinoma. When hepatic stellate cells (HSCs) are activated by liver injury, they transdifferentiate into myofibroblasts, which secrete extracellular ...

Chromatin architecture reorganization during stem cell differentiation

Nature, 2015
Higher-order chromatin structure is emerging as an important regulator of gene expression. Although dynamic chromatin structures have been identified in the genome, the full scope of chromatin dynamics during mammalian development and lineage ...

Dynamics of cell-type transition mediated by epigenetic modifications [PDF]

arXiv, 2023
Maintaining tissue homeostasis requires appropriate regulation of stem cell differentiation. The Waddington landscape posits that gene circuits in a cell form a potential landscape of different cell types, wherein cells follow attractors of the probability landscape to develop into distinct cell types.

Role of PD-1 during effector CD8 T cell differentiation

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance PD-1–mediated inhibitory signals play a major role in T cell exhaustion during chronic infections and cancers, which makes PD-1 a valuable target of checkpoint blockade in cancer immunotherapy.
