AbstractObjectivesWound healing is a complex process with a sequence of restoring and inhibition events such as cell proliferation, differentiation, migration as well as adhesion. Mesenchymal stem cells (MSC) derived conditioned medium (CM) has potent therapeutic functions and promotes cell proliferation, anti-oxidant, immunosuppressive, and anti-apoptotic effects. The main aim of this research is to study the role of human umbilical cord-mesenchymal stem cells (UC-MSCs) derived CM in stimulating the proliferation of human keratinocytes (HaCaT).MethodsFirstly, MSC were isolated from human umbilical cords (UC) and the cells were then cultured in proliferative medium. We prepared and collected the CM after 72 h. Morphological changes were observed after the treatment of HaCaT cells with CM. To validate the findings, proliferation rate, clonal efficiency and also gene expression studies were performed.ResultsIncreased proliferation rate was observed and confirmed with the expression of Proliferating Cell Nuclear Antigen (PCNA) after treatment with HaCaT cells. Cell-cell strap formation was also observed when HaCaT cells were treated with CM for a period of 5–6 days which was confirmed by the increased expression of Collagen Type 1 Alpha 1 chain (Col1A1).ConclusionsOur results from present study depicts that the secretory components in the CM might play a significant role by interacting with keratinocytes to promote proliferation and migration. Thus, the CM stimulates cellular proliferation, epithelialization and migration of skin cells which might be the future promising application in wound healing.

Acute myeloid leukemia (AML) is an aggressive bone marrow malignancy, and non-leukemic stromal cells (including mesenchymal stem cells, MSCs) are involved in leukemogenesis and show AML-supporting effects. We investigated how constitutive extracellular mediator release by primary human AML cells alters proteomic profiles of normal bone marrow MSCs. An average of 6814 proteins (range 6493−6918 proteins) were quantified for 41 MSC cultures supplemented with AML-cell conditioned medium, whereas an average of 6715 proteins (range 6703−6722) were quantified for untreated control MSCs. The AML effect on global MSC proteomic profiles varied between patients. Hierarchical clustering analysis identified 10 patients (5/10 secondary AML) showing more extensive AML-effects on the MSC proteome, whereas the other 31 patients clustered together with the untreated control MSCs and showed less extensive AML-induced effects. These two patient subsets differed especially with regard to MSC levels of extracellular matrix and mitochondrial/metabolic regulatory proteins. Less than 10% of MSC proteins were significantly altered by the exposure to AML-conditioned media; 301 proteins could only be quantified after exposure to conditioned medium and 201 additional proteins were significantly altered compared with the levels in control samples (153 increased, 48 decreased). The AML-modulated MSC proteins formed several interacting networks mainly reflecting intracellular organellar structure/trafficking but also extracellular matrix/cytokine signaling, and a single small network reflecting altered DNA replication. Our results suggest that targeting of intracellular trafficking and/or intercellular communication is a possible therapeutic strategy in AML.

Burn Wound Healing

Abstract Burn wound healing is one of the most important problems in the field of medical science. Promising results have recently been reported by researchers who used bone marrow mesenchymal stem cells (BMSCs) to treat burn wounds. In this study, we investigated the effects of BMSC therapy in combination with simvastatin (SMV) on angiogenesis as well as on the activity of the Akt/mTOR signaling pathway during burn wound healing in rats. After creating second-degree burn wounds, 40 adult male Wistar rats were randomly divided into four treatment groups: the control, SMV, BMSCs, and the combination therapy group (BMSCs+SMV). Animals were killed 14 days after treatment initiation, and the wounds were removed for histological and molecular analyses. All in all, combination therapy produced better outcomes than individual therapy in terms of the wound closure area, epidermal regeneration level, collagen deposition intensity, and reepithelialization rate. In addition, the elevations of expression levels of Akt and mTOR genes, at both mRNA and protein levels, were more pronounced in the BMSCs+SMV group (P < .05, at least, for both qRT-PCR and western blot assessments). qRT-PCR findings also demonstrated that the wounds treated with the combination of BMSCs and SMV had the highest expression levels of CD31 and VEGF genes (P < .01 for all comparisons). These data suggest that the combined administration of BMSCs transplantation and topical SMV has a great potential in burn wound healing. According to the findings, the beneficial effects of the combination therapy are caused, at least in part, through stimulating Akt/mTOR signaling pathway.
