Project description:KRT5+P63+ progenitor cells located in the basal layer of the airway epithelium have been identified as a promising candidate for lung epithelium repair. To gain molecular insights into the fate specification process of human P63+ progenitor cells in the lung, we sorted the transplanted GFP+ cells at different time points using flow cytometry, followed by 10x Genomics single-cell RNA sequencing analysis. Unsupervised clustering of the cells resulted in the identification of 7 distinct populations.

Project description:KRT5+P63+ progenitor cells located in the basal layer of the airway epithelium have been identified as a promising candidate for lung epithelium repair. Such cells are originated from primitive progenitors in distal airways and could expand/migrate to inflamed damaged lung parenchymal region to form ‘saccule’. To further investigate the characteristics and potential function of the saccule structure, we performed the high-resolution spatial transcriptomic analysis on the 35 dpt lung section.

Project description:The possibility of lung regeneration has been long discounted due to the irreversible nature of chronic lung diseases. However, patients who sustain massive loss of lung tissue during acute infections often recover full pulmonary function. Correspondingly, we previously demonstrated lung regeneration in mice following H1N1 influenza virus infection and implicated p63+Krt5+ distal airway stem cells, or DASCp63/Krt5, in this process. We show here that rare, preexisting DASCp63/K5 undergo a proliferative expansion in response to influenza and lineage-trace to nascent alveoli assembled at sites of interstitial inflammation. We also show that the ablation of DASCp63/Krt5 in vivo prevents the regeneration of lung tissue following influenza leading to pre-fibrotic lesions and deficient oxygen exchange. Finally, we demonstrate that exogenously cloned and propagated DASCp63/Krt5 readily contribute to lung regeneration following transplantation. These data suggest that DASCp63/K5 are required for lung regeneration and may have therapeutic utility in acute and chronic lung diseases. Tracheal epithelium and alveoli of healthy mice were laser capture microdissected for microarray analysis. Damaged lung interstitium (CD45+ region) of influenza infected (75pfu H1N1, 15dpi) mice were also dissected. Duplicates were included for each sample. We used the Affymetrix Mouse Exon 1.0 ST platform

DASC stem cells were ablated by Dtox treatment in Krt6:DTR mouse model. Control and stem cell ablated lungs were analyzed. We used the Affymetrix Mouse Exon 1.0 ST platform

Project description:The Vomeronasal organ (VNO) is a part of the accessory olfactory system, which is responsible for detecting pheromones, chemical factors that trigger a spectrum of sexual and social behaviors. The vomeronasal epithelium (VNE) shares several features with the epithelium of the main olfactory epithelium (MOE). However, it is a distinct neuroepithelium populated by chemosensory neurons that differ from the olfactory sensory neurons (OSNs) in cellular structure, receptor expression, and connectivity. The vomeronasal organ of rodents comprises a sensory epithelium and a thin nonsensory epithelium that morphologically resembles the respiratory epithelium. Sox2-positive cells have been previously identified as the stem cell population that gives rise to neuronal progenitors in MOE and VNE. In addition to these, the MOE also comprises p63 positive horizontal basal cells (HBCs), a second pool of quiescent stem cells that become active in response to injury. Immunolabeling against the transcription factor p63, Keratin-5 (Krt5), Krt14 and Krt5Cre tracing experiments highlighted the existence of horizontal basal cells distributed along the basal lamina of the VNO forming from progenitors along the basal lamina oft the marginal zones. Moreover, these experiments revealed that the NSE of rodents is, like the respiratory epithelium, a stratified epithelium where the p63/Krt5+ basal cells self-replicate and give rise to the apical columnar cells facing the lumen of the VNO.
