Human pancreas on a chip opens new possibilities for studying disease

It may be feasible to also use the small two-chambered device, which features bioengineered human pancreatic organoids to study the causes of non-CF-related conditions such as type 1 and 2 diabetes, according to researchers at Cincinnati Children's Hospital Medical Center, who report findings in Nature Communications.

First, however, the scientists want to see if their device can help people with CF -- a genetic lung disease caused by a mutation in the CFTR gene. The mutation leads to a water and salt imbalance on cell surfaces that clogs the lungs with thick mucus.

People - CF - Risk - CFRD - Anjaparavanda

As people with CF get older, they become increasingly at risk for CFRD, according to Anjaparavanda Naren, PhD, the study's principal investigator and Director of the Cystic Fibrosis Research Center (Division of Pulmonary Medicine). Making matters worse is that until now there hasn't been an effective way to study CFRD in the lab to look for better treatments.

"Mouse models of CF don't faithfully recreate CF-Related Diabetes in the lab, and it wasn't possible to study the disease at the depth we achieved in this study," said Naren. "Our technology closely resembles the human pancreas and potentially may help us find therapeutic measures to manage glucose imbalance in people with CF, which is linked to increased illness and death."

Chip - Technology - CFRD - Imbalance - Individuals

The in vitro chip technology can be used to study CFRD and glucose imbalance in specific individuals with the condition, creating the potential for diagnosing different disease manifestations on a highly personalized basis. The chip can help assay variability in the glucose measures of different people, determine correlation of glucose levels with the CFTR mutation type, and test small-molecule interventions.

Although mutations in the CFTR gene are known to cause cystic fibrosis, its role in CFRD is unclear. To answer that...
