Loss of NR2F6 Protects from Salmonella Typhimurium Infection

open access: yesAdvanced Science, EarlyView.
Loss of nuclear receptor NR2F6 reduces tissue‐resident macrophage populations. Nr2f6‐deficient mice are protected from weight loss and bacterial load during infection with Salmonella Typhimurium. Pro‐inflammatory cytokines and iron levels are altered in infected Nr2f6‐deficient mice.

The topological structure of 2D disordered cellular systems

open access: yes, 1997
We analyze the structure of two dimensional disordered cellular systems generated by extensive computer simulations. These cellular structures are studied as topological trees rooted on a central cell or as closed shells arranged concentrically around a ...

Localized ultraviolet laser microbeam irradiation of early Drosophila embryos: Fate maps based on location and frequency of adult defects [PDF]

open access: yes, 1979
Drosophila embryos were locally irradiated with a 257-nm laser microbeam during blastoderm and germ band stages. Depending on stage and beam diameter (10–30 μm), from 0 to 45 nuclei were exposed to the uv radiation.

Germ cell tumor of ovary with plenty of sarcoid like granulomas: A diagnosis on fine needle aspiration cytology

open access: yesJournal of Cytology, 2012
Germ cell tumors of ovary with elements of two or more subtypes are relatively uncommon. Sarcoid-like granulomas are seen in rare association with dysgerminomas, a subgroup of germ cell tumors of ovary, which are again less common. Fine-needle aspiration

Advances in Microfluidic Cochlea‐On‐A‐Chip

open access: yesAdvanced Science, EarlyView.
This review systematically examines diverse cell sources for inner ear organoids and outlines stepwise induction protocols. Furthermore, it discusses current applications and prospective developments of cochlea‐on‐a‐chip technologies in areas such as deafness modeling, mechanistic studies, and drug evaluation, with particular focus on gene‐therapy drug

Tap73 is essential for germ cell adhesion and maturation in testis [PDF]

open access: yes, 2014
A core evolutionary function of the p53 family is to protect the genomic integrity of gametes. However, the role of p73 in the male germ line is unknown.

Stereotyped Subclones Revealed by High‐Density Single‐Cell Lineage Tracing Support Robust Development

open access: yesAdvanced Science, EarlyView.
Based on a well‐established in vitro directed differentiation model and an integrated analysis of high‐density cell lineage trees (CLTs) and single‐cell transcriptomes, it is demonstrated that many subclones are formed by sub‐CLTs resembling each other in terms of both cell type compositions and topological structures.

Single-cell RNA sequencing reveals regulation of fetal ovary development in the monkey (Macaca fascicularis)

open access: yesCell Discovery, 2020
Germ cells are vital for reproduction and heredity. However, the mechanisms underlying female germ cell development in primates, especially in late embryonic stages, remain elusive. Here, we performed single-cell RNA sequencing of 12,471 cells from whole

The Morphological, Behavioral, and Transcriptomic Life Cycle of Anthrobots

open access: yesAdvanced Science, EarlyView.
DNA is thought to determine shape, behavior, and lifespan, with developmental plasticity reserved for stem cells, embryos, and species like amphibia. How much morphogenetic plasticity do adult somatic human cells exhibit? Anthrobots are a self‐organizing, motile synthetic living construct made of genetically normal human epithelial cells.

Differential expression of conserved germ line markers and delayed segregation of male and female primordial germ cells in a hermaphrodite, the leech helobdella. [PDF]

open access: yes, 2013
In sexually reproducing animals, primordial germ cells (PGCs) are often set aside early in embryogenesis, a strategy that minimizes the risk of genomic damage associated with replication and mitosis during the cell cycle.
