What is a brain organoid?

A brain organoid is a 3D structure that is typically grown in vitro from pluripotent stem cells and is engineered to resemble certain aspects of the developing human brain.

By exposing stem cells to specific growth factors and other signaling molecules in a temporal sequence and in a controlled environment, researchers can coax them to differentiate into brain cells and self-organize into brain-like structures.

Brain organoids are small, approximately pea-sized, and contain different types of brain cells, including neurons, astrocytes, and oligodendrocytes. In view of the paucity of available human brain material, organoids can be used as models to study development, test drug efficacy and toxicity, and investigate the underlying mechanisms of neurodegenerative diseases and neurological disorders. While brain organoids are not exact replicas of the human brain, they can provide a readily available tool in a more controlled and ethically acceptable manner than animal models or human embryos.

Blog: Omicron BA.5 infects human brain organoids

COVID-19 has affected human brain organoids. See this blog post about how some BA.5 infected patients are experiencing increased loss of the sense of smell (anosmia).

Growing brain organoids in 3D

Brain organoids can be expanded and maintained in 3D culture systems. These allow for the formation of cell-cell and cell-matrix interactions that are crucial for the formation of complex tissue structures.

One common method for growing brain organoids in 3D culture is to use hydrogels, which are three-dimensional networks of hydrophilic polymers that can mimic the extracellular matrix (ECM) found in vivo. Another approach is to use microfluidic devices, which can provide precise control over the chemical and physical environment of the organoid.

Clinostat 3D culture systems allow researchers to generate larger and more complex brain organoids that can better model the human brain. However, the complexity and heterogeneity of brain organoids present challenges in terms of standardization, reproducibility, and the interpretation of experimental results.

How to grow brain organoids
in the ClinoStar


The ClinoStar is particularly well-suited for growing and expanding brain organoids. It provides a controlled and physiologically relevant culture environment for these complex structures, which can be maintained for weeks or months.

It can also be used to scale up the production of brain organoids for drug discovery and other applications. The system can be used to generate large numbers of brain organoids that are consistent in size and structure, which can improve the reproducibility of experiments and facilitate higher-throughput drug screening.

Bovine blastocyst like structures derived from stem cell cultures

A recent study on a newly developed and efficient method to generate bovine blastocyst-like structures (termed blastoids) via the assembly of trophoblast stem cells and expanded potential stem cells.



Characterization of an Australian outbreak Japanese Encephalitis virus genotype 4 isolate in mice and human cortical brain organoids

DOI: 10.1101/2023.04.26.538504

Researchers characterized the neuropathology of JEV in adult mice and found that the virus caused neuronal degeneration, leukocyte infiltrates, and other brain lesions. The virus was also lethal to some mice and destroyed human neuronal cells in vitro.

Omicron BA.5 infects human brain organoids and is neuroinvasive and lethal in K18-hACE2 mice

DOI: 10.1101/2022.12.22.521696
We show that a BA.5 isolate was significantly more pathogenic in K18-hACE2 mice than a BA.1 isolate, with BA.5 infection showing increased neurovirulence, encephalitis and mortality, similar to that seen for an original ancestral isolate.
