Why is so important? Lung stem cells, whether endogenous or made in the lab, have the potential to help […]

Mere weeks into the COVID pandemic, stunning graphics began to appear depicting the path of devastation of SARS-CoV-2 through a human lung. It’s only recently that we’ve come to understand what, exactly, is happening on a cellular level. The new view is thanks to single-cell RNA-sequencing, which analyzes the abundance of messenger RNAs in individual

On stem cells for lungs the-profit clinic offerings don’t make much sense

lung stem cells, lung health institute

What’s the deal with lung stem cells and stem cells for lungs? For a long time researchers found that stem cells were elusive in adult lungs. There was debate about whether they even existed, but it now seems fairly established that there are some of the little guys in there. Just because one of the
