Hyun Jung Kim has been developing his "gut-on-a-chip" technology for more than a decade. These miniature systems represent accurate models ラーメンベット 入金されない patient's own gut, as well as the disease simulation. The aim is to use the patients’ own cells to test drugs and understand disease processes to determine the right treatment for the patient.
Kim and Woojung Shin, an NIH/NCI F99/K00 fellow previously on Kim’s ラーメンベット 入金されない team, published a new article in the journal Nature Protocols laying out a roadmap to generate a 3D model ラーメンベット 入金されない human intestinal system that can be used as part ラーメンベット 入金されない gut-on-a-chip technology. The researchers first discovered the underlying mechanism in 2019, and this new paper details exactly how they did it, giving others the ability to replicate for their advanced experimentation.
"ラーメンベット 入金されない is such a dynamic environment," said Kim, an assistant professor in the ラーメンベット 禁止ゲーム of Engineering’s Department of Biomedical Engineering. "It's important to provide cells with the right mechanical and biological conditions to grow in a way that mimics our key organs."
Background: In 2019, the researchers published a paper titled: ラーメンベット 入金されない Intestinal Morphogenesis Controlled by Transepithelial Morphogen Gradient and Flow-Dependent Physical Cues in a Microengineered Gut-on-a-Chip in iScience. In it, they were able to demonstrate the ability to grow a 3D gut that accurately mimics the shape and function ラーメンベット 入金されない intestinal system.
Over time, they have refined the formula and are sharing it with the larger ラーメンベット 入金されない community in this new paper. The key to growing this system, a process known as morphogenesis, involves Wnt, which are the proteins that signal cell structures on how they should grow. The removal of a key Wnt antagonist — which inhibits their signaling capabilities — such as Dickkopf-1 (DKK-1) helped generate morphogenesis.
Why It Matters: This model ラーメンベット 入金されない intestinal system is much closer than anything else to mimicking the small or large intestines in our bodies. The previous gold standard used to test drugs in the pharmaceutical industry only produced a thin 2D monolayer that didn’t adequately imitate the dynamics ラーメンベット 入金されない intestinal system. Importantly, such conventional static models have been substantially limited to demonstrating host-microbiome interactions that can potentially orchestrate essential body functions.
A lack of a life-like testing system means the results seen in early experiments may not bear out in ラーメンベット 入金されない trials. Gut-on-a-chip systems allow for customization as well, with the ability to simulate different race, age, diet, gender and more.
What's Next: The researchers plan to continue to tinker with their formula to even better mimic ラーメンベット 入金されない. Now that they understand the signals cells need to grow the right way, the researchers are focused on building personalized gut models as well as speeding up how quickly cells can form the 3D intestinal structures for high-throughput drug tests.
