congenital heart rhythm disorders can be life-threatening, and good treatment is lacking for many patients.The LUMC and Ncardia are accelerating the search for new drugs thanks to an⁢ automated platform. In it, promising substances are quickly and reliably tested on⁤ a mini-heart made from stem cells.

In a heart rhythm disorder, the heart does not beat as⁤ it should. The rhythm can be too fast, too slow, or irregular. This is often due to a ‍problem in the heart’s electrical system.Some heart rhythm disorders are congenital. This means that people have lived with them since birth. These conditions can be life-threatening and sometimes lead to⁤ sudden death.

Although ⁣each individual condition is rare, approximately 1 in‍ 2,000 people worldwide has a congenital heart rhythm disorder. For many of these ⁢patients,there are limited good treatments. this ⁤makes research into new medicines and therapies very crucial.

From stem cell to mini-heart model

The new platform from ⁣the LUMC and Ncardia can play a major role in this. the platform is based on‍ stem cells and offers researchers unique opportunities to study heart rhythm ‍disorders.⁢ Richard Davis, group⁤ leader at ‍the LUMC explains: ‘Stem cells are special cells that can multiply ⁢indefinitely and, under the right conditions, can grow into ⁢almost any cell type in our⁤ body in a laboratory, ⁤including cells of the heart.’

During recent years, stem cell-based heart ⁤models ‍have become increasingly complex. ‘Previously,they consisted of a single flat layer of‍ heart muscle cells grown from stem cells,’ says Davis. ‘Now, the models contain multiple types of ⁣heart cells. These cells work together in small 3D

de ⁢bevindingen ‍van de onderzoekers zijn recent gepubliceerd in het wetenschappelijk tijdschrift Trends⁣ in ⁣Biotechnology.

Andere mogelijke toepassingen

Het platform kan ook gebruikt worden voor andere hartritmestoornissen of om te testen of chemische stoffen schadelijk zijn voor het hart.⁣ ‘Ook kan het mogelijkheden ‍bieden ⁣voor patiënten die niet ⁤reageren op de standaardbehandeling en waarvoor geen goed alternatief beschikbaar is. Met het platform kunnen we mini-hartmodellen maken uit de stamcellen van patiënten.zo kan de behandeling volledig⁢ afgestemd⁢ worden op de‍ patiënt’, sluit Davis af.

Het LUMC is onderdeel van het Leiden Bio Science Park, een ecosysteem waar ⁤bedrijven en kennisinstellingen werken aan ‍biotechnologie en het ontwikkelen van nieuwe‍ geneesmiddelen. Op het park werken talent, startups, bedrijven en onderzoekers dagelijks samen om deze innovaties sneller bij patiënten te⁤ krijgen. Zo maken we de zorg stap voor stap beter en de wereld een⁤ beetje gezonder.

Deze samenwerking werd financieel ondersteund door de‍ Provincie⁤ Zuid-Holland via een Innovatiecampussubsidie, met aanvullende financiering binnen het LUMC vanuit het ⁣Novo Nordisk Foundation Center for Stem Cell Medicine (reNEW).
