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.

We report that the disruption of excitation-contraction coupling contributes to impaired force generation in the mouse model of Sod1 deficiency. Briefly, we found a significant reduction in sarcoplasmic reticulum Ca2+ ATPase (SERCA) activity as well as reduced expression of proteins involved in calcium release and force generation. Another potential factor involved in EC uncoupling in Sod1-/- mice is oxidative damage to proteins involved in the contractile response. In summary, this study provides strong support for the coupling between increased oxidative stress and disruption of cellular excitation contraction mac...

With the development of medical technology, transplantation has prevailed and become an important tool in the treatment of disease. According to the WHO ’s statistics, as of 2015, approximately 120000 cases of solid organ transplantation have been performed globally. Renal transplantation is the most common, followed by liver transplantation, heart transplantation, lung transplantation, hematopoietic stem cell transplantation, etc. [1]. And, in re cipients of transplantation, seizures usually occur during the postoperative period [2,3].

Authors: Hosseinirad H, Rashidi M, Moghaddam MM, Tebyanian H, Nouraei S, Mirhosseini SA, Rasouli M, Habibian S Abstract The respiratory system is a complex group of organs in the human body, all of which are necessary in breathing. Due to its special anatomy and composition, after exposure to various damaging factors such as micro particles, carbon granules and toxic gases, the respiratory system can be affected by a variety of damage without return to its original state. Currently, the prevalence of lung diseases, including asthma, and chronic obstructive pulmonary diseases, such as emphysema, has increased remark...

AbstractAchieving the optimal clinical outcome of mesenchymal stem cells (MSCs) is particularly dependent on fundamental understanding of therapeutic mechanisms. The current study was focused on the possible mechanisms by which rat bone marrow-derived mesenchymal stem cells (rBMMSCs) and/or conditioned media (CM) display broad immunomodulatory properties for ameliorating of asthma-related pathological changes. Male rats were divided equally into four experimental groups (n = 6): healthy rats received 50 μl PBS intravenously (group C), sensitized rats received 50 μl PBS intravenously (group OVA...
