Mitochondrial Disease-Specific Induced Pluripotent Stem Cell Models: Generation and Characterization.
Mitochondrial disease is a group of disorders caused by dysfunctional mitochondria,of which the mutation in the mitochondrial DNA is one of the primary factors. However,the molecular pathogenesis of mitochondrial diseases remains poorly understood due to lack of cell models. Patient-specific induced pluripotent stem cells (iPS cells or iPSCs) are originated from individuals suffering different diseases but carrying unchanged disease causing gene. Therefore,patient-specific iPS cells can be used as excellent cell models to elucidate the mechanisms underlying mitochondrial diseases. Here we present a detailed protocol for generating iPS cells from urine cells and fibroblasts for instance,as well as a series of characterizations.

Cell senescence as both a dynamic and a static phenotype
It has been 50 years since cellular senescence was first described in human diploid fibroblasts (HDFs),yet its mechanism as well as its physiological and clinical implications are still not fully appreciated. Recent progress suggests that cellular senescence is a collective phenotype,composed of complex networks of effector programs. The balance and quality within the effector network varies depending on the cell type,the nature of the stress as well as the context. Therefore,understanding each of these effectors in the context of the whole network will be necessary in order to fully understand senescence as a whole. Furthermore,searching for new effector programs of senescence will help to define this heterogeneous and complex phenotype according to cellular contexts.

In vitro generation of human pluripotent stem cell derived lung organoids.
Recent breakthroughs in 3-dimensional (3D) organoid cultures for many organ systems have led to new physiologically complex in vitro models to study human development and disease. Here,we report the step-wise differentiation of human pluripotent stem cells (hPSCs) (embryonic and induced) into lung organoids. By manipulating developmental signaling pathways hPSCs generate ventral-anterior foregut spheroids,which are then expanded into human lung organoids (HLOs). HLOs consist of epithelial and mesenchymal compartments of the lung,organized with structural features similar to the native lung. HLOs possess upper airway-like epithelium with basal cells and immature ciliated cells surrounded by smooth muscle and myofibroblasts as well as an alveolar-like domain with appropriate cell types. Using RNA-sequencing,we show that HLOs are remarkably similar to human fetal lung based on global transcriptional profiles,suggesting that HLOs are an excellent model to study human lung development,maturation and disease.

Rapid and efficient conversion of integration-free human induced pluripotent stem cells to GMP-grade culture conditions
Data suggest that clinical applications of human induced pluripotent stem cells (hiPSCs) will be realized. Nonetheless,clinical applications will require hiPSCs that are free of exogenous DNA and that can be manufactured through Good Manufacturing Practice (GMP). Optimally,derivation of hiPSCs should be rapid and efficient in order to minimize manipulations,reduce potential for accumulation of mutations and minimize financial costs. Previous studies reported the use of modified synthetic mRNAs to reprogram fibroblasts to a pluripotent state. Here,we provide an optimized,fully chemically defined and feeder-free protocol for the derivation of hiPSCs using synthetic mRNAs. The protocol results in derivation of fully reprogrammed hiPSC lines from adult dermal fibroblasts in less than two weeks. The hiPSC lines were successfully tested for their identity,purity,stability and safety at a GMP facility and cryopreserved. To our knowledge,as a proof of principle,these are the first integration-free iPSCs lines that were reproducibly generated through synthetic mRNA reprogramming that could be putatively used for clinical purposes.
