Lung cell lineage.
In addition the cells must differentiate into at least 40 distinct lung cell lineages.
Reconstructing lineage hierarchies of the distal lung epithelium using single cell rna seq.
Clones x360 x8 and x232 are found contributing to multiple cell lineages multipotent whereas others contribute only to lung lineage x314 lung and pnec x401 and nle only x123.
Single cell atlas of lung innate lymphoid cells.
In the lung alveolus the alveolar type 2 at2 cell population or subpopulations within it is thought to be the predominant epithelial progenitor cell capable of self renewal and generating the alveolar type 1 at1 lineage after injury barkauskas et al 2013.
There is no evidence that a single lung stem cell as in the hematopoietic system gives rise to all cell lineages during homeostasis or repair.
The mammalian lung is a highly branched network in which the distal regions of the bronchial tree transform during development into a densely packed honeycomb of alveolar air sacs that mediate gas exchange.
This reflects the fact that cell specific lineage tracing systems are better developed for the epithelium.
Collectively these experiments indicate that lung epithelial stem cells are regionally specific.
The lung alveolar compartment is the primary site of gas exchange the most fundamental function of the respiratory system.
Specific transcriptional factors peptide growth factor receptor mediated signaling pathways extracellular matrix components and integrin signaling pathways interact to direct lung morphogenesis and lung cell lineage differentiation.
The lung alveolus forms a niche of interacting and communicating cell types including the at1 and at2 epithelial lineages vascular endothelial cells and poorly understood mesenchymal lineages.
Furthermore we validated upregulation of lineage markers of differentiated cell types of the adult lung by qpcr.
Lung lineage specific cell differentiation was achieved in a relatively shorter span of time 22 days in contrast to other reported lung lineage culture conditions.
E lentivirally barcoded cells projected onto the cshmm based using 86 selected genes.
To shed light on these unknown mechanisms scientists at the max planck institute of immunobiology and epigenetics in freiburg headed by dominic.
These culture media normally used to maintain and grow mature cells could successfully induce differentiation of pluripotent embryonic stem cells into three types of mature lung lineage specific non ciliated cells.
