Before And After

Mesenchymal stem cells (MSCs) are multipotent cells and can differentiate into neurons and glial cells. In vitro differentiation would be done by the addition of various factors. There remains no comparison for the differentiation of MSCs from rat bone marrow (rBMMSCs) and adipose tissue (rATMSCS) into neurons and glial cells with basic fibroblast growth factor (bFGF), epidermal growth factor (EGF), and brain‐derived neurotrophic factor (BDNF). The aims of this study were to investigate the effect of bFGF, EGF, and BDNF supplementation on the differentiation ability of rBMMSCs and rATMSCs into neurons and glial cells. MSCs were cultured with bFGF and EGF for 4 days and then BDNF was added until day 8. Characterization of MSCs before and after induction was carried out by observing the cell morphology and several cell markers. Flowcytometry analysis was performed for MSCs markers (CD90, CD29) and neurons and glial cell markers (A2B5, Beta‐III‐tubulin, PSAN‐CAM); while MAP‐2, a neuron marker, was analyzed by immunocytochemistry. Induction of both types of MSCs showed MAP‐2‐positive cells, decreased MSCs markers, and in rBMMSCs showed increased neuron markers. The number of neuron marker positive cells in rBMMSCS was higher than rATMSCs. This study showed that the addition of bFGF, EGF, and BDNF to the medium induced rBMMSCs into neurons and glial cells, but the conditions were not optimal for rATMSC as judged by the expression of neural markers (A2B5, Beta‐III‐tubulin, PSAN‐CAM, and MAP‐2).

Abstract Introduction Critical limb ischemia (CLI) is the most advanced form of peripheral arterial disease (PAD) characterized by ischemic rest pain and non-healing ulcers. Currently, the standard therapy for CLI is the surgical reconstruction and endovascular therapy or limb amputation for patients with no treatment options. Neovasculogenesis induced by mesenchymal stem cells (MSCs) therapy is a promising approach to improve CLI. Owing to their angiogenic and immunomodulatory potential, MSCs are perfect candidates for the treatment of CLI. The purpose of this study was to determine and compare the in vitro and in vivo effects of allogeneic bone marrow mesenchymal stem cells (BM-MSCs) and adipose tissue mesenchymal stem cells (AT-MSCs) on CLI treatment. Methods For the first step, BM-MSCs and AT-MSCs were isolated and characterized for the characteristic MSC phenotypes. Then, femoral artery ligation and total excision of the femoral artery were performed on C57BL/6 mice to create a CLI model. The cells were evaluated for their in vitro and in vivo biological characteristics for CLI cell therapy. In order to determine these characteristics, the following tests were performed: morphology, flow cytometry, differentiation to osteocyte and adipocyte, wound healing assay, and behavioral tests including Tarlov, Ischemia, Modified ischemia, Function and the grade of limb necrosis scores, donor cell survival assay, and histological analysis. Results Our cellular and functional tests indicated that during 28 days after cell transplantation, BM-MSCs had a great effect on endothelial cell migration, muscle restructure, functional improvements, and neovascularization in ischemic tissues compared with AT-MSCs and control groups. Conclusions Allogeneic BM-MSC transplantation resulted in a more effective recovery from critical limb ischemia compared to AT-MSCs transplantation. In fact, BM-MSC transplantation could be considered as a promising therapy for diseases with insufficient angiogenesis including hindlimb ischemia.

Abstract Objectives Hypoxic–ischemic brain damage (HIBD) is a major cause of brain injury in neonates. Bone marrow mesenchymal stem cells (BMSCs) show therapeutic potential for HIBD, and genetic modification may enhance their neuroprotective effects. The goal of this study was to investigate the neuroprotective effects of hepatocyte growth factor (HGF)-overexpressing BMSCs (BMSCs-HGF) against HIBD and their underlying mechanisms. Methods: BMSCs were transfected with HGF using adenoviral vectors. HIBD models were established and then BMSCs were transplanted into the brains of HIBD rats via intraventricular injection. 2,3,5-Triphenyltetrazolium chloride (TTC) staining was used to measure cerebral infarction volumes. In vitro, primary cultured cortical neurons were co-cultured with BMSCs in a Transwell plate system. Oxygen–glucose deprivation (OGD) was applied to imitate hypoxic–ischemic insult, and PD98059 was added to the culture medium to block the phosphorylation of extracellular signal-regulated kinase (ERK). Cell apoptosis was determined using TUNEL staining. The expression of HGF was measured by immunofluorescence, real-time quantitative PCR (RT-qPCR), and western blots. The expression of phosphorylated ERK (p-ERK) and B-cell lymphoma-2 (Bcl-2) was measured by western blots. Results HGF-gene transfection promoted BMSC proliferation. Moreover, BMSCs-HGF decreased HIBD-induced cerebral infarction volumes and enhanced the protective effects of the BMSCs against HIBD. BMSCs-HGF also increased expression of HGF, p-ERK, and Bcl-2 in brain tissues. In vitro, BMSC-HGF protected neurons against OGD-induced apoptosis. Inhibition of ERK phosphorylation abolished the neuroprotective effect of BMSCs-HGF against OGD. Conclusions BMSCs-HGF is a potential treatment for HIBD and that the ERK/Bcl-2 pathway is involved in the underlying neuroprotective mechanism.

Abstract Mesenchymal stem cells (MSC) from bone marrow cavity are multipotent cells. Their primary function is to support the growth and differentiation of hematologic progenitors. MSCs have been shown to differentiate into a variety of cell types including: bone, adipocytes, cartilage, neuron-like, and muscle-like cells. This project aimed to induce MSCs from rat bone marrow into mature dopamine secreting cells. MSCs were isolated from rat bone marrow, cultured and passaged. After propagating for three generations in vitro culture, MSCs were induced by epidermal growth factor, basic fibroblast growth factor and retinoic acid. After induction, morphologic change was examined by light microscope. NSE,MAP-2a, b and tyrosine hydroxylase (TH) was examined by immunocytochemistry. The related genes of the differentiated neurons, such as Nurr-1, nestin, mash-1,DR2-L,AADC and TH were detected by RT-PCR. After MSCs were inducted for 7 days,14 days and 21 days, dopamine production and release in the extract and medium of dopaminergic-induced cultured cells was assayed by dopamine ELISA. After 14 days of induction, MSC showed neuron-like morphologic changes and expressed NSE, MAP-2a, b and TH. RT-PCR. showed that these induced cells expressed nerves stem cells gene Nestin,Nurr-1 and dopamine nerves gene mash-1,DR2-L,AADC,TH. Most importantly, dopamine ELISA analysis showed the evidence of dopamine release in the extract and medium of dopaminergic-induced clonal MSCs. The results suggest that bone marrow MSCs from rat can be induced to differentiate into dopaminergic neuron-like cells in vitro. Bone marrow MSCs will provide a promising source of neural progenitor cells and may be a favorable candidate for cellular therapy of Parkinson’s disease.

IntroductionRegenerative treatment using stem cells represents a potentially effective therapy for cerebellar ataxia (CA). We compared the therapeutic potential of adipose tissue stem cells (ASCs) and bone marrow mesenchymal stem cells (BM-MSCs) in a rodent monosodium glutamate (MSG)-induced CA cell (BM-MSC) model.Material and methodsFemale Wistar rats (n = 40) were equally divided into a saline-treated control group and 3 MSG-induced CA groups randomly treated with either saline, or 1 × 106 ASCs or BM-MSCs. We assessed the following: 1) cerebellar motor functions in vivo (by Rotarod test, open-field test, and Quantitative gait analysis); 2) cerebellar histological architecture; and 3) cerebellar immunohistochemical examination of the Bax/Bcl-2 ratio as in indicator of apoptosis, and the levels of vascular endothelial growth factor (VEGF) and insulin-like growth factor-1 (IGF-1) as neuroprotective factors.ResultsTreatment with either of the MSCs improved MSG-induced poor motor performance, restored the disrupted Purkinje cell layer, decreased neuronal apoptosis and enhanced cerebellar VEGF and IGF-1 levels observed in CA rats. Adipose tissue stem cells showed superiority over BM-MSCs in the improvement of some motor performance parameters and cerebellar VEGF and IGF-1 levels.ConclusionsIn conclusion, both stem cell types induced structural, physiological, and biochemical improvement, with ASCs being best for treatment of CA.
