Role of c-Jun N-terminal kinase in the osteogenic and adipogenic differentiation of human adipose-derived mesenchymal stem cells
Although previous studies have characterized the osteogenic potential of adipose-derived mesenchymal stem cells (AMSCs) in vitro and in vivo, the molecular mechanism involved remains to be fully determined. Previously, we demonstrated that the ERK pathway plays an important role in osteogenesis and...

| 520 | |a Although previous studies have characterized the osteogenic potential of adipose-derived mesenchymal stem cells (AMSCs) in vitro and in vivo, the molecular mechanism involved remains to be fully determined. Previously, we demonstrated that the ERK pathway plays an important role in osteogenesis and regulation of the balance between osteogenesis and adipogenesis. Here, we explored the possible role of JNKs in osteogenesis and adipogenesis of AMSCs. JNK activation in osteo-induced AMSCs was initiated at 15min, peaked at 30min, and declined from 45min to basal levels. Inhibition of the JNK signaling pathway using SP600125 blocked osteogenic differentiation in a dose-dependent manner, which was revealed by an ALP activity assay, extracellular calcium deposition detection, and expression of osteogenesis-relative genes (Runx2, ALP, and OCN) via RT-PCR and real-time PCR. However, blockage of JNK did not induce a switch between osteogenesis and adipogenesis of AMSCs in the presence of dexamethasone, which is different from that of blockage of ERK. Significantly, the blockage of JNK activation in adipo-induced AMSCs by SP600125 stimulated adipogenic differentiation, which was confirmed by Oil Red O staining to detect intracellular lipid droplets, and RT-PCR and real-time PCR analysis for expression of adipogenesis-relative genes (PPARγ2 and aP2). This study suggested a potential function of the JNK pathway in committing osteogenic and adipogenic differentiation of AMSCs in vitro. However, blockage of the JNK pathway is not sufficient to induce a switch from osteogenesis to adipogenesis of AMSCs. | ||

Here, we explored the possible role of JNKs in osteogenesis and adipogenesis of AMSCs. JNK activation in osteo-induced AMSCs was initiated at 15min, peaked at 30min, and declined from 45min to basal levels. Inhibition of the JNK signaling pathway using SP600125 blocked osteogenic differentiation in a dose-dependent manner, which was revealed by an ALP activity assay, extracellular calcium deposition detection, and expression of osteogenesis-relative genes (Runx2, ALP, and OCN) via RT-PCR and real-time PCR. However, blockage of JNK did not induce a switch between osteogenesis and adipogenesis of AMSCs in the presence of dexamethasone, which is different from that of blockage of ERK. Significantly, the blockage of JNK activation in adipo-induced AMSCs by SP600125 stimulated adipogenic differentiation, which was confirmed by Oil Red O staining to detect intracellular lipid droplets, and RT-PCR and real-time PCR analysis for expression of adipogenesis-relative genes (PPARγ2 and aP2). This study suggested a potential function of the JNK pathway in committing osteogenic and adipogenic differentiation of AMSCs in vitro. However, blockage of the JNK pathway is not sufficient to induce a switch from osteogenesis to adipogenesis of AMSCs.

Role of c-Jun N-terminal kinase in the osteogenic and adipogenic differentiation of human adipose-derived mesenchymal stem cells |
| abstract |
Although previous studies have characterized the osteogenic potential of adipose-derived mesenchymal stem cells (AMSCs) in vitro and in vivo, the molecular mechanism involved remains to be fully determined. Previously, we demonstrated that the ERK pathway plays an important role in osteogenesis and regulation of the balance between osteogenesis and adipogenesis. Here, we explored the possible role of JNKs in osteogenesis and adipogenesis of AMSCs. JNK activation in osteo-induced AMSCs was initiated at 15min, peaked at 30min, and declined from 45min to basal levels. Inhibition of the JNK signaling pathway using SP600125 blocked osteogenic differentiation in a dose-dependent manner, which was revealed by an ALP activity assay, extracellular calcium deposition detection, and expression of osteogenesis-relative genes (Runx2, ALP, and OCN) via RT-PCR and real-time PCR. However, blockage of JNK did not induce a switch between osteogenesis and adipogenesis of AMSCs in the presence of dexamethasone, which is different from that of blockage of ERK. Significantly, the blockage of JNK activation in adipo-induced AMSCs by SP600125 stimulated adipogenic differentiation, which was confirmed by Oil Red O staining to detect intracellular lipid droplets, and RT-PCR and real-time PCR analysis for expression of adipogenesis-relative genes (PPARγ2 and aP2). This study suggested a potential function of the JNK pathway in committing osteogenic and adipogenic differentiation of AMSCs in vitro. However, blockage of the JNK pathway is not sufficient to induce a switch from osteogenesis to adipogenesis of AMSCs. |

Previously, we demonstrated that the ERK pathway plays an important role in osteogenesis and regulation of the balance between osteogenesis and adipogenesis. Here, we explored the possible role of JNKs in osteogenesis and adipogenesis of AMSCs. JNK activation in osteo-induced AMSCs was initiated at 15min, peaked at 30min, and declined from 45min to basal levels. Inhibition of the JNK signaling pathway using SP600125 blocked osteogenic differentiation in a dose-dependent manner, which was revealed by an ALP activity assay, extracellular calcium deposition detection, and expression of osteogenesis-relative genes (Runx2, ALP, and OCN) via RT-PCR and real-time PCR. However, blockage of JNK did not induce a switch between osteogenesis and adipogenesis of AMSCs in the presence of dexamethasone, which is different from that of blockage of ERK. Significantly, the blockage of JNK activation in adipo-induced AMSCs by SP600125 stimulated adipogenic differentiation, which was confirmed by Oil Red O staining to detect intracellular lipid droplets, and RT-PCR and real-time PCR analysis for expression of adipogenesis-relative genes (PPARγ2 and aP2). This study suggested a potential function of the JNK pathway in committing osteogenic and adipogenic differentiation of AMSCs in vitro. However, blockage of the JNK pathway is not sufficient to induce a switch from osteogenesis to adipogenesis of AMSCs.</subfield></datafield><datafield tag="520" ind1=" " ind2=" "><subfield code="a">Although previous studies have characterized the osteogenic potential of adipose-derived mesenchymal stem cells (AMSCs) in vitro and in vivo, the molecular mechanism involved remains to be fully determined.
