Scientists have engineered cellular clusters that mimic the functions of the stomach.
Scientists at the Cincinnati Children’s Hospital Medical Centre have induced adult stem cells to differentiate into small clusters of gastric tissue that replicate the functions of the human stomach. The lab-made structures, known as “mini-stomachs”, were created by replicating the chemical pathways of early stage stomach development of stem cells in a petri dish. Continue reading →
Scientists have engineered human intestinal tissue through the use of stem cells.
Researchers from the Cincinnati Children’s Hospital Medical Centre have successfully grown functional human intestinal tissues by utilizing stem cells. After stimulating the stem cells with a “molecular cocktail” of chemicals and growth factors, the team observed as the cells developed into the mucosal lining and muscle layers, while exhibiting digestive functions such as nutrient uptake and responding to molecular signals.

Inflammatory Bowel Disease (IBD) is a group of inflammatory conditions of the colon and small intestine. The major types of IDB are Crohn’s Disease and ulcerative colitis. In the US, approximately 1 million people suffer from diseases that fall under the category of IBD. Treatments for this disease ordinarily include steroids and immune-suppressors. However, researchers at Wake Forest have recently discovered a population of stem cells that may be able to treat IBD without the use of either steroids or immune-suppressors.
