geer Small cell lung cancer (SCLC) accounts for approximately 10–15% of all lung cancers. The prognosis is poor with median survival in the advanced stage remaining at around 12 months. Despite applying every known therapeutic approach, no major breakthrough has improved the overall survival in the last 30 years. Historically, experiments performed on conventional cell lines may have limitations of not accurately reflecting the complex biological and genomic heterogeneity of this disease. However, additional knowledge gained from recently developed genetically engineered mouse models (GEMMs) and patient deriv...

Publication date: Available online 14 October 2019Source: Biochemical Engineering JournalAuthor(s): Jinfeng Li, Guowei Shang, Yisheng Wang, Xiuli Wang, Yuanyuan Ji, Yuebai LiAbstractCalcitonin gene-related peptide (CGRP) promotes proliferation and osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs), which influence bone regeneration and reconstruction. We previously established CGRP-modified BMSCs that express the CGRP gene and demonstrated that this elevated CGRP expression promotes osteogenic differentiation of BMSCs. The current study investigated the therapeutic effects of CGRP-modified BMSCs combi...

Abstract Retinal vascular diseases, such as diabetic retinopathy, retinopathy of prematurity, retinal vein occlusion, ocular ischemic syndrome and ischemic optic neuropathy, are leading causes of vision impairment and blindness. Whilst drug, laser or surgery-based treatments for the late stage complications of many of these diseases are available, interventions that target the early vasodegenerative stages are lacking. Progressive vasculopathy and ensuing ischemia is an underpinning pathology in many of these diseases, leading to hypoperfusion, hypoxia, and ultimately pathological neovascularization and/or edema i...

AbstractPluripotent stem cell (PSC) cultures form an integral part of biomedical and medical research due to their capacity to rapidly proliferate and differentiate into hundreds of highly specialized cell types. This makes them a highly useful tool in exploring human physiology and disease. Genomic editing of PSC cultures is an essential method of attaining answers to basic physiological functions, developing in vitro models of human disease, and exploring potential therapeutic strategies and the identification of drug targets. Achieving reliable and efficient genomic editing is an important aspect of using large-scale PS...

In this study, DECM deposited by synovium-derived MSCs was used as an in vitro expansion system for rabbit articular chondrocytes and the response of DECM-expanded chondrocytes to pro-inflammatory cytokines such as interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) was evaluated. Compared with those grown on tissue culture polystyrene (TCPS), the proliferation rate was significantly improved in DECM-expanded chondrocytes. TCPS- and DECM-expanded chondrocytes were isolated and induced to redifferentiation in a high-density pellet culture. DECM-expanded chondrocytes exerted a stronger resistance...

Mitochondrial dysfunction and mitochondrial DNA damage are significant features of aging. One of the tools used to investigate the role of mitochondria in aging is the lineage of mitochondrial mutator mice. These mice accumulate mutations in mitochondrial DNA quite rapidly, and exhibit accelerated aging. Setting aside the discussion of what exactly qualifies as accelerated aging, researchers here present evidence to suggest that the mitochondrial mutation is not the cause of accelerated aging in this model. Instead, this particular approach to accelerating mitochondrial DNA damage leads in addition to accelerated nuclear D...
