Live imaging of alveologenesis in precision-cut lung slices reveals dynamic epithelial cell behaviour

Precision cut lung slice

Researchers in the Dean lab have published exciting exciting novel insights into alveoli development. Alveoli are the site of gas exchange in the lungs. Damage to alveoli, is a component of many chronic and acute lung diseases such as emphysema and Idiopathic pulmonary fibrosis. In addition, insufficient generation of alveoli results in bronchopulmonary dysplasia, which affects many babies born prematurely. Visualising the process of alveolar development (alveologenesis) is important so that we can begin to explore potential ways to repair and regenerate lung tissue. Because the lungs are situated deep inside the body, it is difficult to see alveologenesis happening in the body. In this study, we have established a new method to visualise this process live, in slices of lung tissue. This is the first time that we have been able to see the process of alveologenesis in real-time.  Our study finds that during alveologenesis, a key type of cells, epithelial cells are highly mobile and we have identified how epithelial cells associate with each other to form new alveoli. We also show that by adding drugs to the slices, we can interfere with the process of alveologenesis. Our study has established a new system that enables us to conduct research on how alveoli form and to test potential treatments to repair damaged alveoli.

NHLI Athena Lecture

9th January 2019

How can we celebrate and support diversity in STEM – a younger perspective’.

 Introduced by Professor Sara Rankin, Head of Equality, Diversity and Inclusion at the NHLI, this year’s lecture broke from tradition by offering a younger perspective on the representation and advancement of women in science. The three guest speakers had been recognised for their commitment to campaigning for diversity in STEM. They each give a 10-15 minute talk followed by a 15 minute Q&A panel facilitated by Dr Mike Cox, a postdoctoral research associate (PDRA) at NHLI and member of the NHLI Athena Self-Assessment Team.

Inspiring and thought-provoking talks from Dr Jess Wade, Dr Faith Uwadiae and Siena Castellon covered many vital themes promoting gender and race equality as well as advocating Neurodiversity.

British Thoracic Society Winter Meeting 2018


British Thoracic Society


The 2018 Winter Meeting was held between 5-7th December at the Queen Elizabeth II Centre, London.


Dr. Charlotte Dean gave her talk entitled “Real-time imaging reveals novel insights into alveologenesis” at the plenary scientific symposium on the 6th December 2018. Charlotte presented recent findings which enlighten our understanding of the process of alveologenesis.

A-level student visit- 10 July 2018

The Dean lab is hosting a visit from 3 A-level students as part of the successful National Heart and Lung Institute Outreach programme. Students spent the afternoon with PhD students, postdocs and lab heads talking about their research. 34 students from different local schools took part in the work experience internships and rotated through four different areas of NHLI to gain insight into a variety of topics.  At the end of the week the students had the opportunity to give an oral/poster presentation to their peers on their favourite topic.
