چکیده

Abstract Background Pulmonary fibrosis (PF) is a growing clinical problem with limited therapeutic options. Human umbilical cord mesenchymal stromal cell (hucMSC) therapy being investigated in trials for the treatment of PF patients. However, little known about underlying molecular and cellular mechanisms hucMSC on PF. In this study, behavior was bleomycin-induced mouse model. Methods The effect hucMSCs lung regeneration determined by detecting Ki67 expression EdU incorporation alveolar type 2 (AT2) fibroblast cells. were transfected to express membrane localized GFP before transplant into lung. tracked staining. Single RNA sequencing performed investigate effects gene profiles macrophages after bleomycin treatment. Results could alleviate collagen accumulation decrease mortality induced bleomycin. transplantation promoted AT2 proliferation inhibited proliferation. By using single sequencing, subcluster interferon-sensitive (IFNSMs) identified infusion. These IFNSMs elevate secretion CXCL9 CXCL10 following infusion recruit more Treg cells injured Conclusions Our study establishes link between hucMSCs, macrophage, Treg, It provides new insights how interact macrophage during repair process play its immunoregulation function.

In-vitro Differentiation of Human Umbilical Cord Wharton’s Jelly Mesenchymal Stem Cells to Insulin-Producing Cells

  Background & Objective: Diabetes is a major chronic metabolic disease in the world. Islet transplantation is a way to treat diabetes. Unfortunately, this method is restricted due to graft rejection and lack of donor islets. Mesenchymal Stem Cells (MSCS) have the ability to differentiate into Insulin-Producing Cells (IPCs). In this study, Human Umbilical Mesenchymal Stem Cells (HUMSCS) were in...

Mesenchymal stem cells attenuate ischemic acute kidney injury by inducing regulatory T cells through splenocyte interactions

The mechanism of mesenchymal stem cell therapy in acute kidney injury remains uncertain. Previous studies indicated that mesenchymal stem cells could attenuate inflammation-related organ injury by induction of regulatory T cells. Whether regulatory T-cell induction is a potential mechanism of mesenchymal stem cell therapy in ischemic acute kidney injury and how these induced regulatory T cells ...

Hypoxia Preconditioning Promotes Survival And Clonogenic Capacity Of Human Umbilical Cord Blood Mesenchymal Stem Cells

Background: In recent decade, human umbilical cord blood derived mesenchymal stem cells (hUCB-MSCs) provide enormous potential for appropriate cell therapy, but they have limited growth potential and cease to proliferate due to cellular senescence, so providing a strategy for increasing the stem cell survival is necessary.  Methods: In this investigation, MSCs characterized by flow cytome...
