Project description:We established a novel alveolar epithelial culture method, called "On-Gel" culture. To characterize the "On-Gel" culture, we compared each transcriptome of the cultured cells in "On-Gel", fibroblast dependent-alveolar organoids (FD-AO) and fibroblast-free alveolar organoids (FF-AO) and their progenitor cells (CPMhigh Lung Progenitors).
Project description:We established a micro-patterned respiratory epithelial cell culture system in vitro. In this culture system, the iPSC-derived lung progenitor cells were differentiated into alveolar epithelial cells in a position-specific manner.
Project description:We established a dual reporter (SFTPC:GFP AGER:mCherry-HiBiT) human iPSC line and the "On-Gel" spheroid culture system suitable for finding the essential signals for alveolar type 2 (AT2) to type 1 (AT1) cell conversion comprehensively. After compound screening, we found that LATS-IN-1 and BAY1125976 synergistically promoted AT1 marker gene expression.
Project description:To investigate the role of alveolar extracellular matrix (aECM) hydrogels on iPSC-derived alveolar type 2 epithelial cell (iAT2) morphological and transcriptional differentiation
Project description:We infected iPSC-derived pulmonary epithelial cells in the micro-patterned culture plate with the SARS-CoV-2 variants. Analyses of infected alveolar and airway epithelial cells, respectively, revealed the tropism of the variants.
Project description:We established a micro-patterned respiratory epithelial cell culture system in vitro. In this culture system, the iPSC-derived lung progenitor cells were differentiated into airway epithelial cells in a position-specific manner.
Project description:The key aim of this experiment is to characterize the iPSC-Mφ population before and after pulmonary transplantation. For this purpose the following cell populations were compared: (i) transplanted iPSC-Mφ, (ii) Mφ obtained by in vitro differentiation of murine lineage-negative bone marrow cells (BM-Mφ), (iii) non-differentiated CD45.1 iPSC, (iv) murine alveolar Mφ (AMφ) isolated from the BALF of healthy control mice, and (v) iPSC-Mφ recovered from the transplanted animals two months after (PMT-Mφ).
