Cell therapy for lung disease? Proof-of-concept study shows promise
Many serious pulmonary diseases, including genetic lung diseases, lack an effective treatment other than the most extreme: lung transplant. A team at Boston Children’s Hospital envisions a much better option: cell therapy, using lung stem cells created from patients’ own cells to repair or replace damaged lung tissue. For patients with genetic lung diseases, the ... Read More
A respiratory model of COVID-19, made from patients’ own cells
What happens in our respiratory tract once COVID-19 invades? A three-dimensional airway model, made from patient-derived stem cells, could provide answers about the initial stages of infection. The model not only replicates the infection process, but can be used to test potential antiviral drugs. Ruby Wang, MD, attending physician in Boston Children’s Division of Pulmonary ... Read More
Can we harness intestinal cells to treat endocrine disorders?
Enteroendocrine cells punch above their weight. Comprising just about 1 percent of intestinal cells, they produce, as a group, around 15 different hormones. These not only regulate intestinal function and digestion, but also influence metabolic functions like insulin secretion and appetite regulation. A new technology platform developed at Boston Children’s could set the stage for ... Read More
How do patients with cystic fibrosis respond to COVID-19? An ‘airway in a dish’ may give answers
So far, based on clinical data, patients with cystic fibrosis (CF) don’t appear to be especially susceptible to COVID-19. And when they do get infected, they don’t seem to get sicker. But Ruobing (Ruby) Wang, MD, who cares for patients with CF in the Division of Pulmonary Medicine at Boston Children’s Hospital, thinks there is ... Read More
Going ‘all in’ for Khori: New hope for congenital enteropathy
Khori LeBlanc is “one of the sassiest and sweetest kids you’ll ever meet,” says her mom, Bryanna Black. Her good mood even carries over to her many hospital visits, where she can be often be found practicing her “karate” moves on the way to an appointment. It’s a resilient attitude that has served her well ... Read More
Lung ‘organoids’ capture early-stage lung cancer; could help test treatments
Lung cancer, the leading cancer killer in the U.S., is often missed in its earlier stages. And while recent imaging advances offer earlier detection, early-stage lung cancers still have no targeted treatments. Key takeaways Mini “organoids” made from lung cells offer a rapid platform for tracking early-stage lung cancers and for testing possible treatments. RNA ... Read More
Creating hairy human skin: Not as easy as you think
Key takeaways· Scientists have created the first cultured human skin capable of growing hair embedded with fat and nerve cells. · Potential applications include burn treatments, and testing medications and cosmetics· The skin organoid system developed is a proof of concept for creating other human organoids, such as the inner ear. For more than 40 ... Read More
Tissue models and a gene therapy for a deadly heart arrhythmia
Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a leading cause of sudden death from cardiac arrest in children and young adults. Marked by racing, irregular heartbeats, the inherited arrhythmia is typically silent until a child suddenly collapses and faints, at an average age of 12. The trigger is an adrenaline surge, caused by exercise or emotional ... Read More
A perfect genetic hit: New gene mutation implicated in rare congenital diarrhea
When the 1-year-old boy arrived from overseas, he was relying on total parenteral nutrition — a way of bypassing the digestive system to provide nutrients and calories completely intravenously — to survive. From the time of his birth, he had experienced unexplainable diarrhea. Answers were desperately needed. Sequencing his genes in search of clues, neonatologists ... Read More
Intestine chip models gut function, in disease and in health
The small intestine is much more than a digestive organ. It’s a major home to our microbiome, it’s a key site where mucosal immunity develops and it provides a protective barrier against a variety of infections. Animal models don’t do justice to the human intestine in all its complexity. Attempts to better model human intestinal function ... Read More
