Most vertebrate organs are composed of epithelium surrounded by support and stromal tissues formed from mesenchyme cells, which are not generally thought to form organized progenitor pools. Here, we use clonal cell labeling with multicolor reporters to characterize individual mesenchymal progenitors in the developing mouse lung. We observe a diversity of mesenchymal progenitor populations with ...

objective(s): electrospun nanofibrous mats of poly(lactic acid) (pla) and nanohydroxyapatite (nano-ha) were prepared and proliferation and differentiation of mesenchymal stem cells on the prepared nanofibers were investigated in this study. materials and methods: pla/nano-ha nanofibers were prepared by electrospinning. the effects of process parameters, such as nano-ha concentration, distance, ...

Background: Mesenchymal stem cells (MSCs) are important candidates for MSC-based cellular therapy. Current paradigm states that MSCs support local progenitor cells in damaged tissue through paracrine signaling. Therefore, study of paracrine effects and secretome of MSCs could lead to the appreciation of mechanisms and molecules associated with the therapeutic effects of these cells. This study ...

Neuroinflammation has a significant role in induce of Multiple sclerosis (MS) many approaches have been used to treat MS, but none of these methods have not been able to fully improve. One of the methods can suppress inflammation and regenerate the nervous system is the use of cell therapy. Using cell therapy in pre-clinic phase can be realized, it's mechanism and potency to suppress neuroinfla...

Reciprocal exchange of morphogenetic proteins between epithelial and mesenchymal cells in a stem/progenitor cell niche results in formation of a nephron. To maintain diffusion of morphogenetic proteins, it is assumed that a close contact exists between involved cells. However, recent publications underline that both types of stem/progenitor cells are separated by a striking interface. To explor...

Formation of a nephron depends on reciprocal signaling of different morphogens between epithelial and mesenchymal cells within the renal stem/progenitor cell niche. Previously, it has been surmised that a close proximity exists between both involved cell types and that morphogens are transported between them by diffusion. However, actual morphological data illustrate that mesenchymal and epithe...

background: the aim of this study was optimization of the polyfect gene delivery method of pcdna3.1 expression vector transfected with the mouse pdx-1 gene in three different kinds of mesenchymal stem cells and hepa cells as well as comparison of transfection efficiency leading to expression of the mentioned gene in the cell types used. materials and methods: rat bone marrow-derived mesenchymal...

September 2016 S. Merfeld-Clauss, D.O. Traktuev, K. L. March The idea of cell therapy using the systemic or local injection of stem/progenitor cells in the area of injury to treat multiple chronic disorders received close attention in the last decade [1]. Bone marrow-derived mesenchymal stem cells (BM-MSC) and blood-derived endothelial progenitor cells were among the first cell types that were ...

The aim of this review was to provide an update on the potential cell therapies restore or replace damaged and/or lost cells in retinal degenerative and optic nerve diseases, describing available sources challenges involved such treatments when these techniques are applied real clinical practice. Sources include human fetal stem cells, allogenic cadaveric adult hippocampal neural CNS ciliary pi...

Introduction  Insulin-like growth factor I (IGF-I) which is produced in abundance in the normal adult liver, is deeply involved in hepatocyte survival, growth, and differentiation during liver development. IGF-I plays the roles via the receptor (IGF-IR) signaling pathway. IGF-IR unlike IGF-I is expressed strongly in the developing liver, but much more weakly in adults. Objective:  We hypothesi...
