Abstract Background. Endometriosis is a common, benign gynecological disease which is determined as an overspreading of endometrial tissue in exterior region of the uterine cavity. Evidence suggests that retrograde menstrual blood which contains mesenchymal stem cells with differential gene expression compared to healthy women may play a role in endometriosis creation. We aimed to identify whether the conditioned medium from Menstrual blood-derived stem cells (MenSCs) of healthy women can affect the expression level of inflammatory and stemness genes of MenSCs from endometriosis women. Methods and Results. Endometriosis derived MenSCs (E-MenSCs) were treated with conditioned medium (CM) derived from healthy women’s MenSCs (NE-MenSCs). Some CD markers were analyzed by flow cytometer before and after treatment compared with NE-MenSCs, and the expression level of inflammatory and stemness genes was evaluated by real-time PCR. Results. E-MenSCs show different morphology in vitro culture in comparison with NE-MenSCs, which were changed in the presence of CM, into a morphology more similar to normal cells and showed significant decrease expression of CD10 after CM treatment. In our results, the IL-1, COX-2, and HIF-1\(\alpha\) as an inflamaturay genes and OCT-4, NANOG, and SOX2 as a stemness genes showed significantly different expression level in E-MenSCs after treating with CM. Conclusions. Our study indicates that the expression level of some inflammatory- and stemness-related genes which have differential expression in E-MenSCs compared with NE-MenSCs, could be changed to normal status by using CM derived from NE-MenSCs.

Аутологичные костномозговые стволовые клетки являются альтернативным способом терапии пациентов с сердечной недостаточностью. Цель работы - изучение фенотипа и функциональных свойств костномозговых мононуклеарных клеток (КМ-МНК) больных хронической сердечной недостаточностью (ХСН) до и после кратковременной экспозиции с эритропоэтином in vitro . Методика. КМ-МНК выделяли на градиенте плотности фиколл/верографин (r = 1,077 г/л). Фенотип КМ-МНК, клеточный цикл и апоптоз CD34+ клеток определяли до и после экспозиции с эритропоэтином на проточном цитометре. Пролиферативный потенциал КМ-МНК до и после экспозиции с эритропоэтином оценивали в спонтанном и стимулирующем тесте. Пролиферацию, миграцию и ангиогенный потенциал клеток EA.hy 929 изучали в тесте «раневого дефекта» монослоя клеток и на матригеле под влиянием 30% кондиционных сред от КМ-МНК. Результаты. Показано, что КМ-МНК представляют собой смесь гемопоэтических стволовых клеток (ГСК), эндотелиальных прогениторных клеток (ЭПК) на разных этапах созревания и дифференцировки, и мезенхимных стволовых клеток (МСК). Под действием эритропоэтина увеличивается количество CD34+ клеток в G0G1 фазе клеточного цикла, CD45+/EpoR+, CD31-/CD184+, CD31+/CD184+ и CD34+/CD184-, и уменьшается количество CD34+/CD133+, CD34+/EpoR-. Кондиционная среда от КМ-МНК способствует пролиферации, миграции и формированию сосудисто-подобных структур клетками EA.hy 929. Заключение. Полученные результаты свидетельствуют, что кратковременная экспозиция КМ-МНК больных ХСН задерживает CD34+ клетки в стадии покоя, увеличивает пул ЭПК, экспрессирующих «хоуминг» рецептор, а кондиционная среда от КМ-МНК стимулирует пролиферацию, миграцию и ангиогенный потенциал EA.hy 929, что следует учитывать при выборе методов усиления «приживаемости» клеточного трансплантата. Autologous bone marrow stem cells are an alternative therapy for patients with heart failure. The aim of this work was to study the phenotype and functional properties of bone marrow mononuclear cells (BM-MNCs) from patients with chronic heart failure (CHF) before and after a short-term in vitro exposure to erythropoietin. Methods. BM-MNCs were isolated using density gradient. The BM-MNC phenotype, cell cycle, and apoptosis of CD34+ cells were evaluated before and after exposure to erythropoietin with a flow cytometer. Proliferation of BM-MNCs before and after the erythropoietin exposure was evaluated in a spontaneous and stimulating test. Proliferation, migration, and angiogenic potential of EA.hy 929 cells were studied in the wound closure test and in the tubule formation test under the influence of 30% conditioned medium from BM-MNCs. Results. BM-MNCs represented a mixture of hematopoietic stem cells (HSCs), endothelial progenitor cells (EPCs) at different stages of maturation and differentiation, and mesenchymal stem cells (MSCs). Erythropoietin increased the number of CD34+ cells in the G0/G1 cell cycle phase, CD45+/EpoR+, CD31-/CD184+, CD31+/CD184+, and CD34+/CD184-, and decreased the number of CD34+/CD133+ and CD34+/EpoR. The erythropoietin exposure of BM-MNCs reduced their proliferative capacity. The BM-MNCs-conditioned medium promoted EA.hy 929 cell proliferation, migration, and formation of vascular-like structures. Conclusion. A short-term exposure of BM-MNCs delayed the resting stage of CD34+ cells, increased the pool of EPCs expressing the homing receptor while the BM-MNC conditioned medium stimulated EA.hy 929 proliferation, migration and tubule formation, which should be taken into account when selecting methods to enhance survival of cellular grafts.

Peripheral nerve injuries are typically caused by either trauma or medical disorders, and recently, stem cell-based therapies have provided a promising treatment approach. Menstrual blood-derived endometrial stem cells (MenSCs) are considered an ideal therapeutic option for peripheral nerve repair due to a noninvasive collection procedure and their high proliferation rate and immunological tolerance. Here, we successfully isolated MenSCs and examined their biological characteristics including their morphology, multipotency, and immunophenotype. Subsequent in vitro studies demonstrated that MenSCs express high levels of neurotrophic factors, such as NT3, NT4, BDNF, and NGF, and are capable of transdifferentiating into glial-like cells under conventional induction conditions. Moreover, upregulation of N-cadherin (N-cad) mRNA and protein expression was observed after neurogenic differentiation. In vivo studies clearly showed that N-cad knockdown via in utero electroporation perturbed the migration and maturation of mouse neural precursor cells (NPCs). Finally, a further transfection assay also confirmed that N-cad upregulation in MenSCs results in the expression of S100. Collectively, our results confirmed the paracrine effect of MenSCs on neuroprotection as well as their potential for transdifferentiation into glial-like cells and demonstrated that N-cad upregulation promotes the neurogenic differentiation of MenSCs, thereby providing support for transgenic MenSC-based therapy for peripheral nerve injury.

Abstract Background Idiopathic pulmonary fibrosis is a kind of diffuse interstitial lung disease, the pathogenesis of which is unclear, and there is currently a lack of good treatment to improve the survival rate. Human menstrual blood-derived mesenchymal stem cells (MenSCs) have shown great potential in regenerative medicine. This study aimed to explore the therapeutic potential of MenSCs for bleomycin-induced pulmonary fibrosis. Methods We investigated the transplantation of MenSCs in a pulmonary fibrosis mouse model induced by BLM. Mouse was divided into three groups: control group, BLM group, MenSC group. Twenty-one days after MenSC transplantation, we examined collagen content, pathological, fibrosis area in the lung tissue, and the level of inflammatory factors of serum. RNA sequence was used to examine the differential expressed gene between three groups. Transwell coculture experiments were further used to examine the function of MenSCs to MLE-12 cells and mouse lung fibroblasts (MLFs) in vitro. Results We observed that transplantation of MenSCs significantly improves pulmonary fibrosis mouse through evaluations of pathological lesions, collagen deposition, and inflammation. Transwell coculturing experiments showed that MenSCs suppress the proliferation and the differentiation of MLFs and inhibit the apoptosis of MLE-12 cells. Furthermore, antibody array results demonstrated that MenSCs inhibit the apoptosis of MLE-12 cells by suppressing the expression of inflammatory-related cytokines, including RANTES, Eotaxin, GM-CSF, MIP-1γ, MCP-5, CCL1, and GITR. Conclusions Collectively, our results suggested MenSCs have a great potential in the treatment of pulmonary fibrosis, and cytokines revealed in antibody array are expected to become the target of future therapy of MenSCs in clinical treatment of pulmonary fibrosis.

Oxidative stress leads to the degeneration of retinal pigment epithelial (RPE) and photoreceptor cells. We evaluated the potential of adipose-derived mesenchymal stem cells (ASCs) as a therapeutic tool by studying the migration capacity of ASCs in vitro and their protective effect against RPE cell death under oxidative stress in vitro and in vivo. ASCs exhibited enhanced migration when exposed to conditioned medium of oxidative stressed RPE cells obtained by hydrogen peroxide. Migration-related axis SDF-1/CXCR4 was studied, and upregulation of SDF-1 in stressed RPE and of CXCR4 in ASCs was detected. Moreover, ASCs’ conditioned medium prevented H2O2-induced cell death of RPE cells. Early passage ASCs had high expression level of HGF, low VEGF levels, and unmodulated IL-1β levels, compared to late passage ASCs. Thus, early passage ASCs show the potential to migrate towards damaged RPE cells and protect them in a paracrine manner from cell death induced by oxidative stress. In vivo, mice received systemic injection of NaIO3, and 72 h later, ASCs were transplanted in the subretinal space. Seven days after ASC transplantation, the eyes were enucleated fixed and frozen for immunohistochemical analysis. Under such conditions, ASC-treated mice showed preservation of nuclear layers in the outer nuclear layer and stronger staining of RPE and photoreceptor layer, compared to PBS-treated mice. Taken together, our results indicate that ASCs are able to home in on damaged RPE cells and protect against damage to the RPE and PR layers caused by oxidative stress. These data imply the potential that ASCs have in regenerating RPE under oxidative stress, providing the basis for a therapeutic approach to retinal degeneration diseases related to oxidative stress that could help save the eyesight of millions of people worldwide.

This study focused on in vivo osteogenic capability of bone marrow mesenchymal stem cells (MSCs) seeded on ceramic scaffold. Human MSCs from a single donor were seeded on hydroxyapatite porous ceramic (HAP) and were induced to the osteogenic lineage during in vitro culture condition, then the MSCs/HAP composites were implanted subcutaneously into immunodeficient rats. The cellular activities of the composites were assayed in order to evaluate the distribution and differentiation capability of seeded MSCs before and after implantation. These results showed that the new bone, after implantation, was derived from the donor MSCs, which adhered to the surface of the ceramics pore areas during in vitro culture. Therefore, the engrafted donor cells proliferated and showed continuous osteogenic differentiation within the recipients. Consequently, our study demonstrates the usefulness of MSCs/HAP composites for clinical applications.
