Abstract
Duchenne and Becker muscular dystrophies are allelic X-linked recessive neuromuscular diseases affecting both skeletal and cardiac muscles. Therefore, owing to their single X chromosome, the affected boys receive pathogenic gene mutations from their unknowing carrier mothers. Current pharmacological drugs are palliative that address the symptoms of the disease rather than the genetic cause imbedded in the Dystrophin gene DNA sequence. Therefore, alternative therapies like gene drugs that could address the genetic cause of the disease at its root are crucial, which include gene transfer/implantation, exon skipping, and gene editing. Presently, it is possible through genetic reprogramming to engineer AAV vectors to deliver certain therapeutic cargos specifically to muscle or other organs regardless of their serotype. Similarly, it is possible to direct the biogenesis of exosomes to carry gene editing constituents or certain therapeutic cargos to specific tissue or cell type like brain and muscle. While autologous exosomes are immunologically inert, it is possible to camouflage AAV capsids, and lipid nanoparticles to evade the immune system recognition. In this review, we highlight current opportunities for Duchenne muscular dystrophy gene therapy, which has been known thus far as an incurable genetic disease. This article is a part of Gene Therapy of Rare Genetic Diseases thematic issue.

Abstract
BACKGROUND INFORMATION Duchenne muscular dystrophy (DMD) is a neuromuscular disease caused by mutations in the gene encoding dystrophin. It leads to repeated cycles of muscle fiber necrosis and regeneration and progressive replacement of fibers by fibrotic and adipose tissue, with consequent muscle weakness and premature death. Fibrosis and, in particular, collagen accumulation are important pathological features of dystrophic muscle. A better understanding of the development of fibrosis is crucial to enable better management of DMD. Three-dimensional (3D) characterization of collagen organization by second harmonic generation (SHG) microscopy has already proven a highly informative means of studying the fibrotic network in tissue. RESULTS Here, we combine for the first-time tissue clearing with SHG microscopy to characterize in depth the 3D cardiac fibrosis network from DMDmdx rat model. Heart sections (1-mm-thick) from 1-year-old wild-type (WT) and DMDmdx rats were cleared using the CUBIC protocol. SHG microscopy revealed significantly greater collagen deposition in DMDmdx versus WT sections. Analyses revealed a specific pattern of SHG+ segmented objects in DMDmdx cardiac muscle, characterized by a less elongated shape and increased density. Compared with the observed alignment of SHG+ collagen fibers in WT rats, profound fiber disorganization was observed in DMDmdx rats, in which we observed two distinct SHG+ collagen fiber profiles, which may reflect two distinct stages of the fibrotic process in DMD. CONCLUSION AND SIGNIFICANCE The current work highlights the interest to combine multiphoton SHG microscopy and tissue clearing for 3D fibrosis network characterization in label free organ. It could be a relevant tool to characterize the fibrotic tissue remodeling in relation to the disease progression and/or to evaluate the efficacy of therapeutic strategies in preclinical studies in DMD model or others fibrosis-related cardiomyopathies diseases.

Abstract
Duchenne muscular dystrophy (DMD), the most common lethal muscular disorder, affects 1 in 5000 male births. It is caused by mutations in the X-linked dystrophin gene (DMD), and there is no effective treatment currently. Gene addition is a promising strategy owing to its universality for patients with all gene mutations types. In this study, we describe a site-specific gene addition strategy in induced pluripotent stem cells (iPSCs) derived from a DMD patient with exon 50 deletion. By using transcription activator-like effector nickases (TALENickases), the mini-dystrophin cassette was precisely targeted at the ribosomal RNA gene (rDNA) locus via homologous recombination with high targeting efficiency. The targeted clone retained the main pluripotent properties and was differentiated into cardiomyocytes. Significantly, the dystrophin expression and membrane localization were restored in the genetic corrected iPSCs and their derived cardiomyocytes. More importantly, the enhanced spontaneous contraction was observed in modified cardiomyocytes. These results provide a proof of principle for an efficient targeted gene addition for DMD gene therapy and represents a significant step toward precisely therapeutic for DMD.

Abstract
Hemophilia A is an X-linked recessive bleeding disorder caused by FVIII gene deficiency, which may result in spontaneous joint hemorrhages or life-threatening bleeding. Currently, cell-based gene therapy via ex vivo transduction of transplantable cells with integrating gene-expressing vectors offers an attractive treatment for HA. In present study, we targeted an expression cassette of B-domain-deleted FVIII into the ribosomal DNA (rDNA) locus of human embryonic stem cells (hESCs) by transfection with a nonviral targeting plasmid pHrn. The targeted hESCs clone could be expanded and retained the main pluripotent properties of differentiation into three germ layers both in vitro and in vivo. Importantly, under defined induction conditions, the targeted hESCs could differentiated into functional mesenchymal stem cells (MSCs) and hepatocytes, as validated by relevant specific cell markers and functional examination. Tumorgenesis assay demonstrated that these cells are relatively safe for future applications. Analysis on gene expression revealed that exogenous FVIII mRNA and FVIII proteins were both present in differentiated MSCs and hepatocytes. These results indicated that through gene targeting at hESCs rDNA locus a persistent cell source of transplantable genetic-modified cells can be accomplished for HA therapy.

Abstract
Emerging evidence indicates that epidermal growth factor (EGF) signaling plays a positive role in myelin development and repair, but little is known about its biological effects on the early generation and differentiation of oligodendrocyte (OL) lineage cells. In this study, we investigated the role of EGF in early OL development with isolated glial restricted precursor (GRP) cells. It was found that EGF collaborated with Platelet Derived Growth Factor-AA (PDGFaa) to promote the survival and self-renewal of GRP cells, but predisposed GRP cells to develop into O4- early-stage oligodendrocyte precursor cells (OPCs) in the absence of or PDGFaa. In OPCs, EGF synergized with PDGFaa to maintain their O4 negative antigenic phenotype. Upon PDGFaa withdrawal, EGF promoted the terminal differentiation of OPCs by reducing apoptosis and increasing the number of mature OLs. Together, these data revealed that EGF is an important mitogen to enhance oligodendroglial development.

Abstract
Mouse primary oligodendrocyte precursor cells (OPCs) are increasingly used to study the molecular mechanisms underlying the phenotype changes in oligodendrocyte differentiation and axonal myelination observed in transgenic or mutant mouse models. However, mouse OPCs are much more difficult to be isolated by the simple dissociation culture of brain tissues than their rat counterparts. To date, the mechanisms underlying the species difference in OPC preparation remain obscure. In this study, we showed that astrocytes from rats have a stronger effect than those from mouse in promoting OPC proliferation and survival in vitro. Mouse astrocytes displayed significantly weaker viability in culture and reduced potential in maintaining OPC self-renewal, as confirmed by culturing OPCs with conditioned media from rat or mouse astrocytes. These results explained the reason for why stratified cultures of OPCs and astrocytes are difficult to be achieved in mouse CNS tissues. Based on these findings, we adopted inactivated rat astrocytes as feeder cells to support the self-renewal of mouse cortical OPCs and preparation of high-purity mouse OPCs. © 2016 Wiley Periodicals, Inc.

Abstract
Although transgenic and knockout mice are widely used to study the specification and differentiation of oligodendrocyte precursor cells (OPCs), mouse primary OPCs are difficult to be purified and maintained, and many in vitro studies have to resort to rat OPCs as substitutes. In this study, we reported that mouse O4 negative early-stage OPCs can be obtained by culturing cortical tissue blocks, and the simultaneous treatment of OPCs with Platelet Derived Growth Factor-AA (PDGFaa), basic fibroblast growth factor (bFGF), and epidermal growth factor (EGF) is the key for the propagation of mouse OPCs in culture. EGF was found to be a potent mitogen for OPCs and cooperate with PDGFaa to extend cell division and inhibit their differentiation. EGF also collaborates with PDGFaa and bFGF to convert bipolar or tripolar OPCs to more vital fibroblast-like OPCs without compromising their oligodendrocyte differentiation potential. In addition, EGF promoted the survival and proliferation of glial progenitor cells (GPCs) derived from primary OPC cultures, and a mixture of GPCs and OPCs can be obtained and propagated in the presence of EGF, bFGF, and PDGFaa. Once EGF is withdrawn, GPC population decreased sharply and fibroblast-like OPCs changed into typical OPCs morphology, then homogeneous OPCs were obtained subsequently.

Abstract
Hemophilia A (HA) is a monogenic disease due to lack of the clotting factor VIII (FVIII). This deficiency may lead to spontaneous joint hemorrhages or life-threatening bleeding but there is no cure for HA until very recently. In this study, we derived induced pluripotent stem cells (iPSCs) from patients with severe HA and used transcription activator-like effector nickases (TALENickases) to target the factor VIII gene (F8) at the multicopy ribosomal DNA (rDNA) locus in HA-iPSCs, aiming to rescue the shortage of FVIII protein. The results revealed that more than one copy of the exogenous F8 could be integrated into the rDNA locus. Importantly, we detected exogenous F8 mRNA and FVIII protein in targeted HA-iPSCs. After they were differentiated into endothelial cells (ECs), the exogenous FVIII protein was still detectable. Thus, it is showed that the multicopy rDNA locus could be utilized as an effective target site in patient-derived iPSCs for gene therapy. This strategy provides a novel iPSCs-based therapeutic option for HA and other monogenic diseases.
