Expanding Genetic Code to Generate Human Brain Organoids with Both Vasculature and Microglia‐Like Cells

open access: yesAdvanced Science, EarlyView.
Using genetic code expansion, we engineered vascularized human cerebral organoids (vhCOs) with microglia‐like cells and blood‐brain barrier features. vhCOs recapitulate neurovascular interactions, regional identities, and neuronal subtypes resembling the fetal brain.

Evaluation of using veliger stage larvae for the preparation of metaphase spreads from the pacific abalone (Haliotis discus hannai)

open access: yesJournal of Animal Reproduction and Biotechnology, 2020
Karyotype analysis is a major work in the process of triploid abalone production for the purpose of productivity and quality improvement. However, the metaphase spreads for karyotype analysis have been prepared just from the larvae at trochophore stage ...

TP53 Loss Elevates NF‐κB‐IFN‐β‐MHC‐Ia Signaling to Promote NK Cell Resistance in Osteosarcoma

open access: yesAdvanced Science, EarlyView.
TP53 loss in a transforming or osteosarcoma cell promotes cytosolic DNA accumulation, activating NF‐κB‐dependent IFN‐β production. Autocrine IFN‐β signaling increases cell‐surface HLA‐Ia expression, strengthens inhibitory KIR signaling in natural killer cells, and thereby enables the affected cell to evade NK cell‐mediated cytotoxicity.

Endowing Flexibility of Alveolar Type II Cells to Recapitulate Development From Lung Bud to Alveoli

open access: yesAdvanced Science, EarlyView.
Adult human alveolar type 2 cells are chemically reprogrammed into expandable alveolar progenitor‐like cells that acquire bud tip‐like features during expansion and form organoids that mature into alveolar‐like structures. These organoids model influenza A virus infection and innate immune responses in vitro, while transplanted cells engraft ...

Molecular karyotyping: from microscope to SNP arrays

open access: yes, 2011
Chromosomal rearrangements are an important cause of distinctive and recognizable clinical phenotypes. For many years conventional karyotyping has been a successful tool to detect such chromosomal rearrangements.

CHD8‐Dependent Chromatin Licensing Sustains Trophoblast Stem Cell Transcriptional Programs

open access: yesAdvanced Science, EarlyView.
In this study, Huang et al., identify chromatin remodeler CHD8 as an essential factor in TSC maintenance and placental development. CHD8‐dependent chromatin accessibility supports the occupancy of key trophoblast TFs and is coupled to KMT2A‐associated H3K4me3 deposition at TSC stem and cell cycle genes, providing a permissive chromatin environment for ...

Pneumocystis carinii karyotypes [PDF]

open access: yesJournal of Clinical Microbiology, 1990
Pulsed-field gel electrophoresis techniques were used to examine the chromosomes of Pneumocystis carinii isolated from laboratory rats and two human subjects. P. carinii organisms isolated from each of four rat colonies and from two patients each produced a distinct band pattern, but in all cases the bands ranged in size from 300 to 700 kilobase pairs.
