Brain-Region-Specific Organoids Using Mini-bioreactors for Modeling ZIKV Exposure

TLDR
A miniaturized spinning bioreactor (SpinΩ) is developed to generate forebrain-specific organoids from human iPSCs that recapitulate key features of human cortical development, including progenitor zone organization, neurogenesis, gene expression, and, notably, a distinct human-specific outer radial glia cell layer.

Modeling Development and Disease with Organoids

TL;DR: 3D culture technology allow embryonic and adult mammalian stem cells to exhibit their remarkable self-organizing properties, and the resulting organoids reflect key structural and functional properties of organs such as kidney, lung, gut, brain and retina, and hold promise to predict drug response in a personalized fashion.

The Human Cell Atlas

Aviv Regev, +81 more
- 05 Dec 2017 - 
TL;DR: An open comprehensive reference map of the molecular state of cells in healthy human tissues would propel the systematic study of physiological states, developmental trajectories, regulatory circuitry and interactions of cells, and also provide a framework for understanding cellular dysregulation in human disease.

Induced pluripotent stem cell technology: a decade of progress

TL;DR: The progress in applications of iPSC technology that are particularly relevant to drug discovery and regenerative medicine are discussed, and the remaining challenges and the emerging opportunities in the field are considered.

Assembly of functionally integrated human forebrain spheroids

TL;DR: Three-dimensional spheroids from human pluripotent stem cells that resemble either the dorsal or ventral forebrain and contain cortical glutamatergic or GABAergic neurons are generated and it is found that in Timothy syndrome—a neurodevelopmental disorder caused by mutations in the CaV1.2 calcium channel—interneurons display abnormal migratory saltations.

Cerebral organoids model human brain development and microcephaly

TL;DR: A human pluripotent stem cell-derived three-dimensional organoid culture system that develops various discrete, although interdependent, brain regions that include a cerebral cortex containing progenitor populations that organize and produce mature cortical neuron subtypes is developed.

Zika Virus Associated with Microcephaly

TL;DR: The case of an expectant mother who had a febrile illness with rash at the end of the first trimester of pregnancy while she was living in Brazil and revealed microcephaly with calcifications in the fetal brain and placenta is described.
Journal ArticleDOI

Organogenesis in a dish: modeling development and disease using organoid technologies.

TL;DR: These studies illustrated two key events in structural organization during organogenesis: cell sorting out and spatially restricted lineage commitment, which are recapitulated in organoids, which self-assemble to form the cellular organization of the organ itself.

Dopamine neurons derived from human ES cells efficiently engraft in animal models of Parkinson’s disease

TL;DR: A novel floor-plate-based strategy for the derivation of human DA neurons that efficiently engraft in vivo is presented, suggesting that past failures were due to incomplete specification rather than a specific vulnerability of the cells.

Zika Virus Infects Human Cortical Neural Progenitors and Attenuates Their Growth

TL;DR: It is shown that a strain of the ZIKV, MR766, serially passaged in monkey and mosquito cells efficiently infects human neural progenitor cells (hNPCs) derived from induced pluripotent stem cells, identified as a direct ZikV target, and reveals transcriptional dysregulation, notably of cell-cycle-related pathways.
