Full textEndothelial cell-based therapies promote tissue regeneration and vascularization after ischemic damage. The availability of autologous endothelial progenitor cells is restricted in diseased patients, however therapeutically relevant numbers of allogeneic Endothelial Progenitor Cells can be isolated from an umbilical cord (UC). In the present study, the immunogenic properties of these Endothelial Colony Forming Cells (ECFCs) were first compared to human umbilical vein endothelial cells (HUVECs). Both cytokine-treated endothelial cells induced CD4+ and CD8+ T cell proliferation after coculture with allogeneic immune cells. So far, the potential interactions between ECFCs and Mesenchymal Stem/Progenitor Cells (MSCs) concerning their immunological features is poorly understood, but we hypothesize that MSCs might improve the immune compatibility and vessel building characteristics of ECFCs. Therefore, human UC-derived ECFC and MSC cocultures from the same donor were analyzed using various functional in vitro and in vivo assays. Stimulation of these cocultures with IFNγ caused strongly reduced expression levels of HLA-molecules compared to ECFC monocultures. The decreased molecular density on the cocultured ECFCs resulted in reduced cytotoxic CD8+ T cell-mediated lysis. Further, during IFNγ stimulation, the combination of ECFCs with MSCs prevented initiation of allogeneic T cell proliferation. To verify this concept in vivo, ECFCs and MSCs were co-transplanted in a humanized allograft mouse model in immunodeficient mice in order to effectively induce stable microvessels. These experiments demonstrate that when MSCs are co-applied with ECFCs, they not only support the formation of stable blood vessels, but also lead to fewer HLA-DR+ human vascular structures and fewer infiltrating human leukocytes. The data presented indicate that crosstalk between UC-derived ECFCs and MSCs might lower the risk of allogeneic ECFC rejection.

Full textThe membrane current pattern of oligodendrocytes changes dramatically during cell development. In oligodendrocyte precursor cells the membrane conductance is dominated by outwardly rectifying potassium channels, mature oligodendrocytes on the other hand express passive, not voltage-gated potassium channels. The activity of these channels influences the proliferation and differentiation of the cells. In the present work the expression of outwardly-rectifying potassium channels of the Kv1-type (Shaker-type) was analysed in oligodendrocyte precursor cells in culture. Expression of Kv1 transcripts, Kv1 proteins as well as electrophysiological and pharmacological properties of these channels were tested. Different combinations of Kv1.1, Kv1.4, Kv1.5 and Kv1.6 transcripts were detected at mRNA level. In some cells also a significant amount of Kv1.2 and Kv1.3 transcripts was found. The heterogeneity of transcript expression could not be correlated with differences in electrophysiological properties. The expression of Kv1 channel proteins was analysed using immunocytochemical stainings with specific monoclonal antibodies against the channel molecules Kv1.1 to Kv1.6. All oligodendrocyte precursor cells expressed the channel molecules Kv1.4 (85 % of the cells), Kv1.5 (99 %) and Kv1.6 (99 %), Kv1.1 proteins were detected in 10 % of the cells. To find out the functional contribution of Kv1 channels to the whole-cell current of the cells the activation and inactivation characteristics as well as the sensitivity of the potassium current to different potassium channel specific antagonists was tested. Parts of the current were inhibited by TEA (1-100 mM), 4-AP (0,125-1 mM) and Chinidin (5-100 mM), CTX, DTX and MCDP had no effect on the channel activity. To isolate the contribution of the channel molecules Kv1.1 and Kv1.4 the electrophysiological properties of the whole cell current electrophysiological analysis of single cells using whole-cell patch-clamp technique and immunocytochemical stainings were combined. With this method no significant differences between Kv1.1/Kv1.4-positive and Kv1.1/Kv1.4 negative cells could be detected. From these findings the following conclusions could be drawn: Oligodendrocyte precursors express various different Kv1 transcripts.The majority of oligodendrocyte precursor cells expresses the Kv1 proteins Kv1.4, Kv1.5 and Kv1.6.The total current (whole-cell current) most likely is carried through Kv1.5 channels or a combination of Kv1.4/Kv1.6 channels and probably another type of voltage-gated potassium channels. To find out if voltage-gated potassium channels are related to the activation of inhibitory neurotransmitter receptors a model system of cultured granule cells was used. This cell type was selected because they are known to express a high density of Kv channels as well as GABAA receptors as well. The activity of single outwardly rectifying potassium channels was detected using the cell-attached mode of patch-clamp technique. With this method it could be demonstrated that the open probability of voltage-gated potassium channels is markedly decreased during GABAA response. It could be concluded that the activation of GABAA receptors on oligodendrocyte precursor cells leads to the inhibition of potassium channels in the same way as in cultured granule cells.
