Stem/progenitor cells in lung development, injury repair, and regeneration.
At least two populations of epithelial stem/progenitor cells give rise to the lung anlage, comprising the laryngo-tracheal complex versus the distal lung below the first bronchial bifurcation. Amplification of the distal population requires FGF9-FGF10-FGFR2b-Sprouty signaling. Residual pools of adult stem cells are hypothesized to be the source of lung regeneration and repair. These pools have ...
متن کاملEpithelial progenitor cells in lung development, maintenance, repair, and disease.
The vertebrate lung is elegantly patterned to carry out gas exchange and host defense. Similar to other organ systems, endogenous stem and progenitor cells fuel the organogenesis of the lung and maintain homeostasis in the face of normal wear and tear. In the context of acute injury, these progenitor populations are capable of effecting efficient repair. However, chronic injury, inflammation, a...
متن کاملLung Basal Stem Cells Rapidly Repair DNA Damage Using the Error-Prone Nonhomologous End-Joining Pathway
Lung squamous cell carcinoma (SqCC), the second most common subtype of lung cancer, is strongly associated with tobacco smoking and exhibits genomic instability. The cellular origins and molecular processes that contribute to SqCC formation are largely unexplored. Here we show that human basal stem cells (BSCs) isolated from heavy smokers proliferate extensively, whereas their alveolar progenit...
متن کاملStem cells and repair of lung injuries
Fueled by the promise of regenerative medicine, currently there is unprecedented interest in stem cells. Furthermore, there have been revolutionary, but somewhat controversial, advances in our understanding of stem cell biology. Stem cells likely play key roles in the repair of diverse lung injuries. However, due to very low rates of cellular proliferation in vivo in the normal steady state, ce...
متن کاملImmunohistological and electrophysiological characterization of Globose basal stem cells
Objective(s): In the past few decades, variety of foetal, embryonic and adult stem and progenitor cells have been tried with conflicting outcome for cell therapy of central nervous system injury and diseases. Cellular characteristics and functional plasticity of Globose basal stem cells (GBCs) residing in the olfactory epithelium of rat olfactory mucosa have not been studied in the past by the ...
