Converting stem cells into lung cells

Researchers from the Columbia University Medical Center claim they are one step closer to generating lung tissue for transplant using a patient's own cells. The study, published in Nature Biotechnology, states that scientists have successfully transformed human stem cells into functioning lung and airway cells. They claim this has great potential for modelling lung disease, screening drugs and, ultimately, generating lung tissue for transplantation. Study leader Dr.

Authors: Bondeelle L, Bergeron A Abstract INTRODUCTION: Progress in allogeneic hematopoietic stem cell transplantation (HSCT) procedures have been associated with improved survival in HSCT recipients. However, they have also brought to light organ-specific complications, especially pulmonary complications. In this setting, pulmonary complications are consistently associated with poor outcomes, and improved management of these complications is required. Areas covered: We review the multiple infectious and noninfectious lung complications that occur both early and late after allogeneic HSCT. This includes the descrip...

Abstract Bronchiolitis obliterans (BO) is a serious lung complication that can develop after allogenic stem cell transplantation. It has been suggested that single nucleotide polymorphisms (SNPs) that affect the NOD2/CARD15 gene impair its function and result in an uncontrolled innate immune response in the recipient, thereby leading to BO. One hundred eighty-one donor-recipient pairs were analyzed for the association between NOD2 gene variants (SNP8 [Arg702Trp], SNP12 [Gly908Arg], and SNP13 [Leu1007fsinsC]) and the occurrence of BO. Ten patients (2.8 %) developed this complication. The incidence of BO increases i...

In conclusion, this is the first report to show that pyroptotic cell death occurs in the aging brain and that the inflammasome can be a viable target to decrease the oxidative stress that occurs as a result of aging. Reducing Levels of Protein Manufacture Slows Measures of Aging in Nematodes https://www.fightaging.org/archives/2018/12/reducing-levels-of-protein-manufacture-slows-measures-of-aging-in-nematodes/ Researchers here demonstrate that an antibiotic slows aging in nematode worms, providing evidence for it to work through a reduction in protein synthesis. Beyond a slowing of aging, one of the con...

Heart transplantation is the definitive treatment for end-stage heart failure. A shortage of donor hearts forced transplant programs to accept older donors and longer ischemic times. Previous studies have suggested that the administration of mesenchymal stem cells (MSCs) or their conditioned medium (CM) protects the heart against ischemia/reperfusion injury (IRI). We hypothesized that the preservation of donor hearts with a CM would protect the graft from IRI after prolonged storage in 15-month-old rats and investigated mRNA-changes attributable to CM.

Abstract Although pulmonary diseases account for a large number of deaths in the world, most have no treatment other than transplantation. New therapeutic methods for lung treatment include lung tissue engineering and regenerative medicine. Lung decellularization has been used to produce an appropriate scaffold for recellularization and implantation. We investigated 3-[(3-cholamidopropyl) dimethylammonio]-1-propanesulfonate (CHAPS) with sodium dodecyl sulfate (SDS) and Triton X-100 detergents for effecting rat lung decellularization. We evaluated using conventional histology, immunofluorescence staining and SEM me...

Discussion Severe-combined immunodefiency (SCID) is actually a group of inherited disorders with an absence or dysfunction of T, B and NK cells that results in severe dysfunction of the immune system. SCID is a primary immunodeficiency. SCID was thought to be a rare disorder but with the advent of neonatal screening the incidence in the US general population is estimated at ~1 in 58,000 live births, but with numbers higher or lower depending on the specific population. Patients often have failure to thrive, oral candidiasis, and diarrhea as infants as well as a variety of infectious diseases. They can also have interstit...

Authors: Yabuki H, Watanabe T, Oishi H, Katahira M, Kanehira M, Okada Y Abstract Ischemia-reperfusion injury (IRI) is one of the main causes of primary graft dysfunction that accounts for 25% of mortality after lung transplantation. Disruption of blood supply and subsequent reperfusion result in organ damage with activating innate and adaptive immune response, leading to inflammatory insults. The IRI after lung transplantation is primarily manifested by permeability pulmonary edema on the basis of pulmonary vascular endothelial cell injury as seen in acute respiratory distress syndrome (ARDS). Stem cells have poten...

Background. Diffuse cutaneous systemic sclerosis (SSc) is a multi-system chronically progressive and debilitating autoimmune connective tissue disease affecting internal organs, characterized by a dysregulated immune system and the production of autoantibodies. Patients experience progressive cumulative mortality despite currently available immunosuppressive therapies.Objective. To assess the safety and efficacy of hematopoietic stem cell transplantation (SCT) with the research question: "what is the relative effect on overall mortality in patients with SSc and internal organ involvement treated with SCT compared to t...
