ETV2 Mediated Differentiation of Human Pluripotent Stem Cells Results in Functional Endothelial Cells for Engineering Advanced Vascularized Microphysiological Models

Advanced Healthcare Materials, EarlyView.
A robust method to generate functional human iPSC‐derived endothelial cells using inducible ETV2 expression. These cells self‐organize into stable, lumenized microvascular networks within microfluidic chips, surpassing conventional differentiation methods.

Non-random Mis-segregation of Human Chromosomes

Cell Reports, 2018
Summary: A common assumption is that human chromosomes carry equal chances of mis-segregation during compromised cell division. Human chromosomes vary in multiple parameters that might generate bias, but technological limitations have precluded a ...

Genome-wide high-resolution mapping of UV-induced mitotic recombination events in Saccharomyces cerevisiae. [PDF]

, 2013
In the yeast Saccharomyces cerevisiae and most other eukaryotes, mitotic recombination is important for the repair of double-stranded DNA breaks (DSBs). Mitotic recombination between homologous chromosomes can result in loss of heterozygosity (LOH).

Two‐Photon 3D Printing of Functional Microstructures Inside Living Cells

Advanced Materials, EarlyView.
This study demonstrates 3D printing inside living cells by using two‐photon photo‐lithography. A bio‐compatible photoresist is injected into cells and selectively polymerized with a femtosecond laser, creating custom‐shaped intracellular structures with submicron resolution.

Random Chromosome Partitioning in the Polyploid Bacterium Thermus thermophilus HB27

G3: Genes, Genomes, Genetics, 2019
Little is known about chromosome segregation in polyploid prokaryotes. In this study, whether stringent or variable chromosome segregation occurs in polyploid thermophilic bacterium Thermus thermophilus was analyzed.

Age-cumulative effect of REC8 reduction on meiotic chromosome segregation errors in mice

Reproductive and Developmental Medicine, 2021
Objective: This study aimed to explore the relationship between cohesin subunit REC8 reduction and meiosis chromosome segregation errors in the ovary. Methods: Rec8+/− mice were generated using CRIPSR/Cas9 gene editing.

Contrasting roles of condensin I and condensin II in mitotic chromosome formation [PDF]

, 2012
© 2012. Published by The Company of Biologists LtdIn vertebrates, two condensin complexes exist, condensin I and condensin II, which have differing but unresolved roles in organizing mitotic chromosomes.

Cell Cycle Control of Nuclear Metabolism Couples Phosphatidylinositol Signaling to Histone Methylation

Advanced Science, EarlyView.
Nuclear metabolism oscillates during cell cycle progression. Quantitative chromatome proteomics and imaging reveal phase‐specific dynamics of PIP5K1A and nuclear PIP2, linking phosphatidylinositol metabolism to histone methylation. This work identifies nuclear lipid metabolism as a previously unrecognized regulatory axis coordinating chromatin ...

MPS1 promotes timely spindle bipolarization to prevent kinetochore-microtubule attachment errors in oocytes

The EMBO Journal
Incorrect kinetochore–microtubule attachment leads to chromosome segregation errors. The risk of incorrect attachment is high in acentrosomal oocytes, where kinetochores are surrounded by randomly oriented microtubules until spindle bipolarization ...

Bacterial chromosome segregation.

Acta Biochimica Polonica, 2005
In most bacteria two vital processes of the cell cycle: DNA replication and chromosome segregation overlap temporally. The action of replication machinery in a fixed location in the cell leads to the duplication of oriC regions, their rapid separation to the opposite halves of the cell and the duplicated chromosomes gradually moving to the same ...
