MesenCult™-ACF Chondrogenic Differentiation Medium Induces Robust Chondrogenic Differentiation of Human MSCs

Figure 1. MesenCult™-ACF Chondrogenic Differentiation Medium Induces Robust Chondrogenic Differentiation of Human MSCs

Human BM-derived MSCs were cultured in MesenCult™-ACF Medium then differentiated to the chondrogenic lineage using MesenCult™-ACF Chondrogenic Differentiation Medium. Robust chondrogenic differentiation was observed (A) starting with as few as 3 x 105 MSCs, or (B) when differentiating for just 14 days starting with 5 x 105 MSCs.

Chondrogenic Differentiation of Human MSCs Is More Robust With Fewer Hypertrophic Chondrocytes Using MesenCult™-ACF Chondrogenic Differentiation Medium Compared to Competitor Media

Figure 2. Chondrogenic Differentiation of Human MSCs Is More Robust With Fewer Hypertrophic Chondrocytes Using MesenCult™-ACF Chondrogenic Differentiation Medium Compared to Competitor Media

Human BM-derived MSCs culture-expanded for up to two passages in MesenCult™-ACF Medium, serum-based medium, or one of two commercially available media (Competitor 1 (Ex1) and Competitor 2 (Ex2)), were then differentiated to the chondrogenic lineage starting with 5 x 105 MSCs and either using MesenCult™-ACF Chondrogenic Differentiation Medium or one of several commercially available chondrogenic differentiation media (Ch1, Ch2 or Ch3) for 21 days. More robust and uniform chondrogenic differentiation was observed when the MSCs were differentiated in MesenCult™-ACF Chondrogenic Differentiation Medium compared to the other commercially available chondrogenic differentiation media (Ch1, Ch2 and Ch3), irrespective of the expansion medium used to culture the MSCs prior to differentiation. Cultures differentiated using MesenCult™-ACF Chondrogenic Differentiation Medium displayed an abundance of isogenous groups (yellow arrows), suggesting there is proliferation of differentiating chondrocyte progenitors. Few hypertrophic chondrocytes (black arrows) are seen in cultures differentiated with MesenCult™-ACF Chondrogenic Differentiation Medium, suggesting the maintenance of chondrogenic activity throughout the culturing period.

MesenCult™-ACF Chondrogenic Differentiation Medium Induces Stronger and More Sustained Chondrogenic Transcript Expression Compared to Competitor Media

Figure 3. MesenCult™-ACF Chondrogenic Differentiation Medium Induces Stronger and More Sustained Chondrogenic Transcript Expression Compared to Competitor Media

Human BM-derived MSCs expanded in (A) MesenCult™-ACF Medium, (B) a serum-based medium or (C) Competitor 2 (Ex2) medium, were differentiated for 21 days with MesenCult™-ACF Chondrogenic Differentiation Medium and Competitor 2 (Ch2) chondrogenic differentiation medium. Regardless of the expansion medium initially used to culture the MSCs, differentiation using MesenCult™-ACF Chondrogenic Differentiation Medium led to a substantial up-regulation of the chondrogenic transcripts compared to Ch2. In addition, expression of the terminally-differentiated hypertrophic transcript Mmp13 was higher for Ch2 differentiated cultures compared to cultures differentiated with MesenCult™-ACF Chondrogenic Differentiation Medium.

Mouse MSCs Cultured in MesenCult™-ACF Chondrogenic Differentiation Medium Differentiate to Chondrocytes

Bone marrow mesenchymal stem cells alleviate the daunorubicin-induced subacute myocardial injury in rats through inhibiting infiltration of T lymphocytes and antigen-presenting cells.

Q. Chen et al.

Abstract

INTRODUCTION Bone marrow mesenchymal stem cells (BMSCs) have been extensively investigated from a perspective on cardiac regeneration therapy. The current study aimed to investigate the protective effect conferred by BMSCs in subacute myocardial injury, and to identify an appropriate BMSC reinfusion time. METHODS BMSCs were isolated from human bone marrow blood. Daunorubicin (DNR)-induced subacute myocardial models were subsequently established. The rats with DNR-induced subacute myocardial injury were injected with dexrazoxane (DZR) and/or BMSCs at varying time points, after which cardiac function was evaluated by assessing left ventricular ejection fraction (LVEF) and fraction shortening (FS). The myocardial structural changes were analyzed, after which the levels of CD3 and human leukocyte antigen DR (HLA-DR) were examined to further validate the mechanism by which BMSCs could influence subacute myocardial injury. RESULTS BMSCs combined with DZR treatment enhanced the cardiac function of rats with DNR-induced myocardial injury, as reflected by increased LVEF and FS. DNR-induced myocardial injuries were mitigated via the application of BMSCs combined with treatment of DZR, accompanied by diminished infiltration or vacuolization. Moreover, BMSCs were observed to alleviate infiltration of T lymphocyte and antigen-presenting cells, as evidenced by reduced expression of CD3 and HLA-DR. CONCLUSION Taken together, this study demonstrates that BMSCs could protect against DNR-induced myocardial injury, especially in the first three days of DNR administration. BMSCs combined with DZR exert a better therapeutic effect, but there are individual differences.

Tofacitinib Reprograms Human Monocytes of IBD Patients and Healthy Controls Toward a More Regulatory Phenotype.

F. Cordes et al.

Abstract

BACKGROUND The inhibition of Janus kinases (JAKs) and subsequent signal transducers and activators of transcription (STATs) by tofacitinib represents a new therapeutic strategy in inflammatory bowel diseases (IBD) as clinical trials have led to approval of tofacitinib for ulcerative colitis (UC) and hint at a possible efficacy for Crohn`s disease (CD). However, the impact of tofacitinib on cellular response of monocytes, which are key players in inflammatory responses, has not been investigated so far. We aimed to analyze JAK/STAT-inhibition by tofacitinib in monocytes of IBD patients and healthy controls. METHODS Primary monocytes of IBD patients with active disease and healthy controls (n = 18) were analyzed for cytokine expression and phenotype after granulocyte macrophage colony-stimulating factor (GM-CSF)/interferon (IFN)$\gamma$-stimulation and tofacitinib pretreatment (1-1000 nM) and capacity to induce Foxp3+-regulatory T cells (Tregs) in cocultures. In total, 20 UC patients and 21 CD patients were included. Additionally, dose-dependent inhibition of JAK/STAT-phosphorylation was analyzed in controls. RESULTS Pro-inflammatory costimulation with GM-CSF/IFN$\gamma$ resulted in significant tumor necrosis factor (TNF$\alpha$) and interleukin (IL)-6 increase, whereas IL-10 expression decreased in monocytes. Tofacitinib modulated the responses of activated monocytes toward a regulatory phenotype through reduced TNF$\alpha$ and IL-6 secretion and enhanced Treg induction in cocultures. However, in monocytes from active IBD patients, higher tofacitinib dosages were needed for blockade of pro-inflammatory cytokines. Tofacitinib induced stronger regulatory phenotypes in monocytes of UC patients, including more effective inhibition of pro-inflammatory pathways and better restoration of anti-inflammatory mechanisms as compared with CD-derived monocytes. CONCLUSION Tofacitinib dose-dependently reprograms monocytes toward a more regulatory cell type. This beneficial effect possibly results from selective JAK/STAT-blockade by adequate tofacitinib dosage with inhibition of pro-inflammatory responses and permission of a balance-shift toward regulatory pathways.

Mesenchymal Stem/Stromal Cells Derived from Dental Tissues: A Comparative In Vitro Evaluation of Their Immunoregulatory Properties Against T cells.

M. D. P. De la Rosa-Ruiz et al.

Abstract

Bone marrow mesenchymal stem/stromal cells (BM-MSCs) have immunoregulatory properties and have been used as immune regulators for the treatment of graft-versus-host disease (GVHD). Human dental tissue mesenchymal stem cells (DT-MSCs) constitute an attractive alternative to BM-MSCs for potential clinical applications because of their accessibility and easy preparation. The aim of this in vitro study was to compare MSCs from dental pulp (DP-MSCs), gingival tissue (G-MSCs), and periodontal ligament (PDL-MSCs) in terms of their immunosuppressive properties against lymphoid cell populations enriched for CD3+ T cells to determine which MSCs would be the most appropriate for in vivo immunoregulatory applications. BM-MSCs were included as the gold standard. Our results demonstrated, in vitro, that MSCs from DP, G, and PDL showed immunoregulatory properties similar to those from BM, in terms of the cellular proliferation inhibition of both CD4+- and CD8+-activated T-cells. This reduced proliferation in cell co-cultures correlated with the production of interferon-$\gamma$ and tumor necrosis factor alpha (TNF-$\alpha$) and the upregulation of programmed death ligand 1 (PD-L1) in MSCs and cytotoxic T-cell-associated Ag-4 (CTLA-4) in T-cells and increased interleukin-10 and prostaglandin E2 production. Interestingly, we observed differences in the production of cytokines and surface and secreted molecules that may participate in T-cell immunosuppression in co-cultures in the presence of DT-MSCs compared with BM-MSCs. Importantly, MSCs from four sources favored the generation of T-cell subsets displaying the regulatory phenotypes CD4+CD25+Foxp3+ and CD4+CD25+CTLA-4+. Our results in vitro indicate that, in addition to BM-MSCs, MSCs from all of the dental sources analyzed in this study might be candidates for future therapeutic applications.

Mesenchymal stromal cells lower platelet activation and assist in platelet formation in vitro.

A. Mendelson et al.

Abstract

The complex process of platelet formation originates with the hematopoietic stem cell, which differentiates through the myeloid lineage, matures, and releases proplatelets into the BM sinusoids. How formed platelets maintain a low basal activation state in the circulation remains unknown. We identify Lepr+ stromal cells lining the BM sinusoids as important contributors to sustaining low platelet activation. Ablation of murine Lepr+ cells led to a decreased number of platelets in the circulation with an increased activation state. We developed a potentially novel culture system for supporting platelet formation in vitro using a unique population of CD51+PDGFRalpha+ perivascular cells, derived from human umbilical cord tissue, which display numerous mesenchymal stem cell (MSC) properties. Megakaryocytes cocultured with MSCs had altered LAT and Rap1b gene expression, yielding platelets that are functional with low basal activation levels, a critical consideration for developing a transfusion product. Identification of a regulatory cell that maintains low baseline platelet activation during thrombopoiesis opens up new avenues for improving blood product production ex vivo.

Promoting Osteogenic Differentiation of Human Adipose-Derived Stem Cells by Altering the Expression of Exosomal miRNA.

S. Yang et al.

Abstract

Human adipose-derived stem cells (ADSCs) can release exosomes; however, their specific functions remain elusive. In this study, we verified that exosomes derived from osteogenically differentiated ADSCs can promote osteogenic differentiation of ADSCs. Furthermore, in order to investigate the importance of exosomal microRNAs (miRNAs) in osteogenic differentiation of ADSCs, we used microarray assays to analyze the expression profiles of exosomal miRNAs derived from undifferentiated as well as osteogenically differentiated ADSCs; 201 miRNAs were upregulated and 33 miRNAs were downregulated between the two types of exosomes. Additionally, bioinformatic analyses, which included gene ontology analyses, pathway analysis, and miRNA-mRNA-network investigations, were performed. The results of these analyses revealed that the differentially expressed exosomal miRNAs participate in multiple biological processes, such as gene expression, synthesis of biomolecules, cell development, differentiation, and signal transduction, among others. Moreover, we found that these differentially expressed exosomal miRNAs connect osteogenic differentiation to processes such as axon guidance, MAPK signaling, and Wnt signaling. To the best of our knowledge, this is the first study to identify and characterize exosomal miRNAs derived from osteogenically differentiated ADSCs. This study confirms that alterations in the expression of exosomal miRNAs can promote osteogenic differentiation of ADSCs, which also provides the foundation for further research on the regulatory functions of exosomal miRNAs in the context of ADSC osteogenesis.
