Organoids are three-dimensional cell cultures from embryonic stem cells or induced pluripotent stem cells that model important features of whole organs.
Researchers at Johns Hopkins Medicine say they have created a laboratory-grown three-dimensional "organoid" model that is derived from human tissue and designed to advance understanding about how early stages of cancer develop at the gastroesophageal junction (GEJ) — the point where the digestive system's food tube meets the stomach.
The development of “mini eyes” by researchers at the UCL Great Ormond Street Institute of Child Health (UCL GOS ICH) has made it possible to study and comprehend the onset of blindness in the rare genetic disease known as Usher syndrome more.
Researchers have opened a new avenue for investigations of neurological development, disease, and therapies that cannot be undertaken in living people by employing stem cells to grow small brain-like structures in the lab.
AZoLifesciences speaks to Dr. Anneline Pinson and Prof. Dr. Wieland B. Huttner from The Max Planck Institute of Molecular Cell Biology and Genetics about their latest research which found a greater neuron production in the frontal lobe during brain development in modern humans than Neandertals, due to the change of a single amino acid in the protein TKTL1.
Great ape animal experiments have long been prohibited in Europe due to ethical concerns. An alternative to using animals in investigations is the use of organoids, which are three-dimensional cell structures that can be generated in the lab and are only a few millimeters in size.
It could be the world's tiniest EEG electrode cap, created to measure activity in a brain model the size of a pen dot. Its designers expect the device to lead to better understanding of neural disorders and how potentially dangerous chemicals affect the brain.
With organoids to model early growth, scientists employed a developing microscopy technology to observe that new neurons find it hard to reach their developmental goal.
As part of our SLAS Europe 2022 coverage, we speak to Professor Jeremy Simpson from the University College Dublin about the role high-content screening can play in accelerating drug discovery.
Researchers at Karolinska Institutet in Sweden show how a molecule that they have identified stimulates the formation of new insulin-producing cells in zebrafish and mammalian tissue, through a newly described mechanism for regulating protein synthesis.
Professor Zi-Bing Jin is in charge of this research (Beijing Institute of Ophthalmology, Beijing Tongren Eye Center, Beijing Tongren Hospital, and Capital Medical University). He has spent the last decade working on retinal organoids, which can accurately mimic retinal development.
A stomach adult stem cell population can fulfill two distinct functions: either help with digestion under normal conditions or take the lead on injury response. S
How do human cells organize themselves to give the organs their ultimate shape? The solution is morphogenesis, a collection of systems that controls their spatial distribution throughout embryonic development. In this sector, a team from the University of Geneva (UNIGE) recently discovered an unexpected discovery: when a tissue curves, the volume of the cells that makes it up grows rather than decreases.
In a study published May 02, 2022 in Nature Communications, scientists at University of California San Diego School of Medicine used human brain organoids to reveal how a genetic mutation associated with a profound form of autism disrupts neural development.
A vaccine for hepatitis C has eluded scientists for more than 30 years, for several reasons. For one, the virus that causes the disease comes in many genetic forms, complicating the creation of a widely effective vaccine.
Intestinal cells can change specializations during their lives. The BMP signaling pathway – an important communication mechanism between cells – appears to be the driver of these changes.
Drug resistance is a major obstacle in the treatment of cancers. In an aggressive type of pancreatic cancer, for instance, drug resistance is associated with the suppression of programmed cell death, which results in the uncontrolled growth of cancer cells.
Infections with several pathogens simultaneously increase the risk of cervical cancer—these results from a study conducted on artificial 3D tissue models.
Preclinical models that recapitulate aspects of human airway disease are essential for the advancement of novel therapeutics and vaccines.
Single-cell RNA sequencing is an approach that lets researchers to study the gene expression in an individual cell within a mixed population.
Ulcerative colitis is an inflammatory bowel disease (IBD) that causes inflammation and ulcers (sores) in the digestive tract. Ulcerative colitis affects the innermost lining of the colon and rectum.
