| 4&', 6-diamidino-2-phenylindole dihydrochloride (DAPI) is a DNA dye widely used to mark and trace stem cells in therapy. We here studied the effect of DAPI staining on the behavior of mesenchymal stem cells cultured in either a control, non-osteogenic medium or in an osteogenic differentiation medium. In the control medium, the number of stem cells/field, as well as the number of fluorescent cells/field increased up to the sixth day in both control and DAPI-treated cultures. Afterwards, both the number of fluorescent cells and their fluorescence intensity decreased. Control cells were fusiform and with some long extensions that apparently linked them to neighboring cells, while DAPI-treated cells were mostly round cells with fine and short extensions.... |

| Human bone marrow-derived mesenchymal stem cells (hMSCs) have the capacity to differentiate into osteoblasts during osteogenesis. Several studies attempted to identify osteogenesis-related genes in hMSCs. Although HOX genes are known to play a pivotal role in skeletogenesis, their function in the osteogenesis of hMSCs has not yet been investigated in detail. Our aim was to characterize the expression of 37 HOX genes by multiplex RT-PCR to identify the ones most probably involved in osteogenic differentiation. The results showed that the expression patterns of four HOX genes were altered during this process. In particular, the expression levels of HOXC13 and HOXD13 were dramatically changed. Real-time PCR and Western blot analysis were performed... |

| ABSTRACT The objective was to evaluate the in vitro effect of prolactin in osteogenic potential of adipose tissue-derived mesenchymal stem cells (ADSCs) in female rats. ADSCs were cultured in osteogenic medium with and without the addition of prolactin and distributed into three groups: 1) ADSCs (control), 2) ADSCs with addition of 100ng/mL of prolactin and 3) ADSCs with addition of 300ng/mL of prolactin. At 21 days of differentiation, the tests of MTT conversion into formazan crystals, percentage of mineralized nodules and cells per field and quantification of genic transcript for alkaline phosphatase, osteopontin, osteocalcin, bone sialoprotein, BMP-2 and collagen I by real-time RT-PCR were made. The addition of prolactin reduced the conversion of MTT in... |

| ABSTRACT A natural agent that maintains mesenchymal stem cell (MSCs) viability, promotes osteogenic differentiation while modulating the immunological response could achieve success in regeneration during healing and may also prevent bone resorption and improve regeneration. We aimed to demonstrate that a Thymbra spicata var. intricata extract could induce proliferation, differentiation, and modulate the immune responses of mesenchymal stem cells (MSCs). Using xCELLigence, a real-time monitoring system, we obtained a growth curve of MSCs. A dose of 10 µg/mL was the most efficient concentration for vitality. Osteogenic differentiation and antiinflammatory activities were determined by using an ELISA Kit to detect early and late markers of differentiation.... |
