Resident stem/progenitor cells in the lung are important for tissue homeostasis and repair. However, a progenitor population for alveolar type II (ATII) cells in adult human lungs have not been identified. Here we isolated alveolar epithelial progenitor cells (AEPCs) from adult human lungs. AEPCs showed mesenchymal stem cell (MSC)-like characteristics combined with ATII cell-phenotypes. AEPCs had the capability for self-renewal and the potential to generate ATII cells in vitro. Furthermore, cells expressing similar markers were present within alveolar walls in normal lungs and these cells were significantly increased in ATII cell hyperplasias. These results suggest that adult human lungs contain a progenitor population for ATII cells.

View SamplesHuman mesenchymal stem cells (hMSCs), which are multipotent cells to differentiate into several cell types, are expected to be a useful tool for cellular therapy. In some clinical settings, hMSCs have immuno-suppressive effects for GVHD (Graft-versus-host disease) and are expanded in vitro before application. To find biomarkers that indicate the culture stage of hMSCs, we performed microarray analysis for hMSCs derived from bone marrow, using Affymetrix GeneChip Human Genome U133 Plus 2.0 (54,613 probe sets).

View SamplesProstate cancer is the most common cancer in men and AR downstream signalings promote prostate cancer cell proliferation. Androgen-deprivation therapy is the first-line treatment strategy for advanced prostate cancer. However, many tumors develop to castration-resistant prostate cancer (CRPC) and relapse. Thus, analyzing key factors for development of CRPC is important. We found PSF functions as RNA binding protein and transcription factor to promote castration-resistant tumor growth. High expression of PSF in metastatic prostate cancer tissue indicates the clinical relevance.

View SamplesAlveolar epithelial type II (ATII) cells play a critical role in homeostasis and repair process of the lungs. In lung diseases such as chronic obstructive pulmonary disease (COPD), ATII cells are damaged and fall into apoptosis or senescence. Until to date, global gene expression of ATII cells in COPD lungs has not been analyzed. We isolated ATII cells from three non-COPD and three COPD patients using a FACS method. Then, we performed microarray analysis to compare gene expression profiles of ATII cells between non-COPD and COPD patients.
