A stem cell molecular signature

NB Ivanova, JT Dimos, C Schaniel, JA Hackney… - Science, 2002 - science.org
Mechanisms regulating self-renewal and cell fate decisions in mammalian stem cells are
poorly understood. We determined global gene expression profiles for mouse and human …

Visualizing structure and transitions in high-dimensional biological data

…, A Elzen, MJ Hirn, RR Coifman, NB Ivanova… - Nature …, 2019 - nature.com
The high-dimensional data created by high-throughput technologies require visualization
tools that reveal data structure and patterns in an intuitive form. We present PHATE, a …

The timing of cortical neurogenesis is encoded within lineages of individual progenitor cells

…, TN Phoenix, IR Lemischka, NB Ivanova… - Nature …, 2006 - nature.com
In the developing cerebral cortex, neurons are born on a predictable schedule. Here we
show in mice that the essential timing mechanism is programmed within individual progenitor …

[PDF][PDF] RETRACTED: shRNA Knockdown of Bmi-1 Reveals a Critical Role for p21-Rb Pathway in NSC Self-Renewal during Development

CA Fasano, JT Dimos, NB Ivanova, N Lowry… - Cell stem cell, 2007 - cell.com
Knockout studies have shown that the polycomb gene Bmi-1 is important for postnatal, but
not embryonic, neural stem cell (NSC) self-renewal and have identified the cell-cycle …

[PDF][PDF] A non-canonical BCOR-PRC1. 1 complex represses differentiation programs in human ESCs

…, J Jin, Y Kluger, TA Neubert, VJ Bardwell, NB Ivanova - Cell stem cell, 2018 - cell.com
Polycomb group proteins regulate self-renewal and differentiation in many stem cell systems.
When assembled into two canonical complexes, PRC1 and PRC2, they sequentially …

[PDF][PDF] Dppa2/4 facilitate epigenetic remodeling during reprogramming to pluripotency

…, I Kumar, M Astudillo, TA Neubert, S Guo, NB Ivanova - Cell Stem Cell, 2018 - cell.com
As somatic cells are converted into induced pluripotent stem cells (iPSCs), their chromatin is
remodeled to a pluripotent configuration with unique euchromatin-to-heterochromatin ratios, …

[PDF][PDF] PHATE: a dimensionality reduction method for visualizing trajectory structures in high-dimensional biological data

…, W Chen, MJ Hirn, RR Coifman, NB Ivanova… - …, 2017 - pdfs.semanticscholar.org
In recent years, dimensionality reduction methods have become critical for visualization,
exploration, and interpretation of high-throughput, high-dimensional biological data, as they …

[HTML][HTML] Nuclear hormone receptors and their ligands: metabolites in control of transcription

LJ Tao, DE Seo, B Jackson, NB Ivanova, FR Santori - Cells, 2020 - mdpi.com
Nuclear hormone receptors are a family of transcription factors regulated by small molecules
derived from the endogenous metabolism or diet. There are forty-eight nuclear hormone …

Visualizing structure and transitions for biological data exploration

…, MJ Hirn, RR Coifman, NB Ivanova… - Available at SSRN …, 2018 - papers.ssrn.com
With the advent of high-throughput technologies measuring high-dimensional biological
data, there is a pressing need for visualization tools that reveal data structure and emergent …

Visualizing transitions and structure for high dimensional data exploration
