Abstract Background Nontuberculous Mycobacterium infections, particularly abscessus, are increasingly common among patients with cystic fibrosis and chronic bronchiectatic lung diseases. Treatment is challenging due to intrinsic antibiotic resistance. Bacteriophage therapy represents a potentially novel approach. Relatively few active lytic phages available there great variation in phage susceptibilities M. abscessus isolates, requiring personalized identification. Methods isolates from 200...
Abstract Epithelial-mesenchymal transition (EMT) occurs during embryonic development and may also be associated with the metastatic spread of epithelial tumors. During EMT, E-cadherin is down-regulated this correlates increased motility invasion cells. We show that differentiation human stem (ES) cells in monolayer culture an E- to N-cadherin switch, vimentin expression, up-regulation repressor molecules (Snail Slug proteins), gelatinase (matrix metalloproteinases; MMP-2 MMP-9) activity...
To develop an embryoid body-free directed differentiation protocol for the rapid generation of functional vascular endothelial cells derived from human embryonic stem (hESCs) and to assess system microRNA regulation angiogenesis.The production defined cell lineages hESCs is a critical requirement evaluating their potential in regenerative medicine. We developed feeder- serum-free protocol. Directed revealed loss pluripotency markers progressive induction mRNA protein expression (including...
Rationale: Optimization of cell therapy for cardiac repair may require the association different populations with complementary activities. Objective: Compare reparative potential saphenous vein–derived pericytes (SVPs) that stem cells (CSCs) in a model myocardial infarction, and investigate whether combined transplantation provides further improvements. Methods Results: SVPs CSCs were isolated from vein leftovers coronary artery bypass graft surgery discarded atrial specimens transplanted...
Epithelial-mesenchymal transition (EMT) events occur during embryonic development and are important for the metastatic spread of epithelial tumors. We show here that spontaneous differentiation mouse stem (ES) cells is associated with an E- to N-cadherin switch, up-regulation E-cadherin repressor molecules (Snail Slug proteins), gelatinase activity (matrix metalloproteinase [MMP]-2 -9), increased cellular motility, all characteristic EMT events. The 5T4 oncofetal antigen, previously shown be...

Background Living grafts produced by combining autologous heart‐resident stem/progenitor cells and tissue engineering could provide a new therapeutic option for definitive correction of congenital heart disease. The aim the study was to investigate antigenic profile, expansion/differentiation capacity, paracrine activity, pro‐angiogenic potential cardiac pericytes assess their engrafting capacity in clinically certified prosthetic grafts.

Abstract Aims Long non-coding RNAs (lncRNAs) play functional roles in physiology and disease, yet understanding of their contribution to endothelial cell (EC) function is incomplete. We identified lncRNAs regulated during EC differentiation investigated the role LINC00961 its encoded micropeptide, small regulatory polypeptide amino acid response (SPAAR), function.

Abstract Background Children with cystic fibrosis (CF) can develop life-threatening infections of Mycobacterium abscessus. These present a significant clinical challenge, particularly when the strains involved are resistant to antibiotics. Recent evidence within-patient subclones M. abscessus in adults CF suggests possibility that diversity may be relevant for treatment pediatric patients. Methods We performed whole-genome sequencing (WGS) on 32 isolates were taken from multiple body sites 2...
<b>Background:</b> Recent reports have shown evidence of host derived parenchymal engraftment in several human allografts including the lung, leading to speculation that stem cell therapy may be useful for lung repair diseases such as cystic fibrosis (CF). To date, previous studies looked at single surgical or autopsy specimens and no longitudinal been reported. The aim this study was assess whether transbronchial biopsies could used time course chimerism following transplantation....

Cell therapy represents a promising option for revascularization of ischemic tissues.However, injection dispersed cells is not optimal to ensure precise homing into the recipient's vasculature.Implantation cell-engineered scaffolds around occluded artery may obviate these limitations.Here, we employed synthetic polymer polycaprolactone (PCL) fabrication 3D woodpile-or channel-shaped by computer-assisted writing system (Pressure Assisted Micro-syringe Square (PAM 2 )), followed deposition...
The E-protein transcription factors play essential roles in lymphopoiesis, with E12 and E47 (hereafter called E2A) being particularly important B cell specification maturation. E2A gene is also involved a chromosomal translocation that results the leukemogenic oncoprotein E2A-PBX1. two activation domains of E2A, AD1 AD2, display redundant, independent, cooperative functions cell-dependent manner. by binding transcriptional co-activator CBP/p300; this interaction required oncogenesis occurs...
Abstract Background Mycobacterium abscessus infection has been associated with variable outcomes following lung transplantation. M comprises three subspecies ( subsp , massiliense and bolletii ). We investigated whether transplantation outcome in cystic fibrosis (CF) patients a single center was related to the genetic cluster.
