GSE158690 Expression data of dermal cells with and without small molecules treatment

Contributors : Junren Sia ; Song LiSeries Type : Expression profiling by arrayOrganism : Mus musculusTraumatic injury often results in muscle loss and impairment, which is worsened under aged and diseased conditions. Activation of resident stem cells or transplantation of myogenic stem cells can promote muscle regeneration. However, major challenges remain in harvesting sufficient autologous myogenic stem cells and expanding such cells efficiently for muscle regeneration therapies. Here, we identified a chemical cocktail that selectively induced a robust expansion of myogenic stem cells from readily-obtainable dermal cells and from muscle stromal cells. By differential plating and lineage tracing, we showed that Pax7+ cells were the major source for chemical-induced myogenic stem cells (CiMCs). We further performed single-cell RNA sequencing (scRNA-seq) analysis to characterize the transcriptomic profile of CiMCs and demonstrate a specific expansion of myogenic cells from heterogeneous dermal cell population. Upon transplantation into the injured muscle, CiMCs were efficiently engrafted and improved functional muscle regeneration in both adult and aged mice. In addition, CiMC transplantation rescued muscle function in mice with Duchenne muscular dystrophy (DMD). Furthermore, an in situ therapeutic modality using this cocktail was developed by loading the chemical cocktail into injectable nanoparticles, which enabled a sustained release of the cocktail in injured muscle and a ...

This study demonstrates for the first time that senescent cells secrete functional LTs, significantly contributing to the LTs pool known to cause or exacerbate idiopathic pulmonary fibrosis. Against Senolytics https://www.fightaging.org/archives/2019/11/against-senolytics/ There is no consensus in science that is so strong as to have no heretics. So here we have an interview with a naysayer on the matter of senolytic treatments, who argues that the loss of senescent cells in aged tissues will cause more harm to long-term health than the damage they will do by remaining. To be clear, I think this to be a ...

Conclusion and Perspectives The IL-6/JAK/STAT signaling cascade plays a dominant role in skeletal muscle pathophysiology. IL-6 autocrine, paracrine, and endocrine functions assign to its downstream effectors pivotal importance in skeletal muscle-wasting-associated diseases and other multiple system diseases where muscle acts in communication with other organs. Targeting the components of the JAK/STAT pathway recently emerged as a strategic approach for the treatment of inflammatory diseases and human cancer. This review highlights the opposite outcomes on muscle biology caused by the amount of local and systemic release ...

In this study, we report the age-associated differences between fetal MSC (fMSC) populations and MSCs isolated from elderly donors with respect to their transcriptomes. We successfully reprogrammed fMSCs (55 days post conception) and adult MSC (aMSC; 60-74 years) to iPSCs and, subsequently, generated the corresponding iMSCs. In addition, iMSCs were also derived from ESCs. The iMSCs were similar although not identical to primary MSCs. We unraveled a putative rejuvenation and aging gene expression signature. We show that iMSCs irrespective of donor age and cell type re-acquired a similar secretome to that of th...

When Noah Shulman was born a few days after Christmas 2016, his parents Kristelle and Evan had no reason to worry about him. The pregnancy went smoothly, and so did the birth. But within a few days of taking his first breath, Noah began to struggle. He wasn’t feeding, so he started losing weight. He was also lethargic. Several pediatricians reassured the Shulmans that they were probably just overly sensitive to Noah’s symptoms because Kristelle is a nurse and Evan is a physician assistant–a case of first-time-parent-white-coat syndrome. “They kind of dismissed us as neurotic parents,” says Eva...

One of the major areas of focus in regenerative research is finding ways to enhance the ability of transplanted cells to integrate with tissue, survive, and induce healing and growth. In early, first generation stem cell therapies, near all cells die quite quickly. The span of benefits that result is a reaction of native cells to the molecular signals briefly generated by the transplanted cells. The anti-inflammatory effects of mesenchymal stem cell therapies as presently practiced is a good example. One way to improve cell survival is to build an artificial environment that to some degree mimics the extracellular ...

In January, 2018, Academic Press published my bookPrecision Medicine and the Reinvention of Human Disease. This book has an excellent " look inside " at itsGoogle book site, which includes the Table of Contents. In addition, I thought it might be helpful to see the topics listed in the Book's index.
