Effects of Cellular Senescence on Human Mesenchymal Stem Cells

ABSTRACT: In the present study we analyzed the effect of cellular senescence on the transcriptome of human mesenchymal stem cells (hMSC; alternatively named mesenchymal stromal cells) from bone marrow. Human MSC were isolated from femoral heads of non-osteoporotic donors after total hip arthroplasty.

Effects of Cellular Senescence on Human Mesenchymal Stem Cells

Project description:In the present study we analyzed the effect of cellular senescence on the transcriptome of human mesenchymal stem cells (hMSC; alternatively named mesenchymal stromal cells) from bone marrow. Human MSC were isolated from femoral heads of non-osteoporotic donors after total hip arthroplasty. Cells were isolated from human bone marrow according to the previously described protocol (Noth et al., 2002, J Orthop Res, 20/5, 1060-1069) under agreement of the local Ethics Committee of the University of Würzburg. Bone marrow was obtained of femoral heads after total hip arthroplasty due to osteoarthritis and/or hip dysplasia. MSC were replated after reaching 70-90% confluence until they entered state of cellular senescence. RNA samples of control cells were taken from passage 1 or passage 2.

Effects of Primary Osteoporosis and Advanced Age on Human Mesenchymal Stem Cells

Project description:In the present study we analyzed the effect of primary osteoporosis and advanced donor age on the transcriptome of human mesenchymal stem cells (hMSC; alternatively named mesenchymal stromal cells) from bone marrow. Human MSC of elderly patients suffering from osteoporosis were isolated from femoral heads after low-energy fracture of the femoral neck. Control cells were obtained from bone marrow of femoral heads of middle-aged, non-osteoporotic donors after total hip arthroplasty. Cells were isolated from human bone marrow according to the previously described protocol (Noth et al., 2002, J Orthop Res, 20/5, 1060-1069) under agreement of the local Ethics Committee of the University of Würzburg. Human MSC of elderly patients suffering from osteoporosis were isolated from femoral heads after low-energy fracture of the femoral neck. Additional criteria for confirming primary osteoporosis in these donors were vertebrae fractures and advanced age. Bone marrow of middle-aged, non-osteoporotic donors was obtained of femoral heads after total hip arthroplasty due to osteoarthritis and/or hip dysplasia. RNA samples were taken from passage 1 or passage 2.

Effects of Primary Osteoporosis on Human Mesenchymal Stem Cells

Project description:In the present study we analyzed the effect of primary osteoporosis on the transcriptome of human mesenchymal stem cells (hMSC; alternatively named mesenchymal stromal cells) from human bone marrow. Human MSC of elderly patients suffering from osteoporosis were isolated from femoral heads after low-energy fracture of the femoral neck. Bone marrow of age-matched, non-osteoporotic donors was obtained of femoral heads after total hip arthroplasty. Cells were isolated from human bone marrow according to the previously described protocol (Noth et al., 2002, J Orthop Res, 20/5, 1060-1069) under agreement of the local Ethics Committee of the University of Würzburg.

Effects of aging on Human Mesenchymal Stem Cells

Project description:In the present study we analyzed the effect of advanced donor age on the transcriptome of human mesenchymal stem cells (hMSC; alternatively named mesenchymal stromal cells) from bone marrow. Human MSC of elderly and middle-aged patients without symptoms of osteoporosis were isolated from femoral heads after total hip arthroplasty. Cells were isolated from human bone marrow according to the previously described protocol (Noth et al., 2002, J Orthop Res, 20/5, 1060-1069) under agreement of the local Ethics Committee of the University of Würzburg. Bone marrow was obtained of femoral heads after total hip arthroplasty due to osteoarthritis and/or hip dysplasia. RNA samples were taken from passage 1 or passage 2.

Mesenchymal Stromal Cells of Different Donor Age

Project description:In this series we have analyzed the effect of donor age on the gene expression profile of mesenchymal stromal cells (alternatively named mesenchymal stem cells; MSC) from human bone marrow. Cells were taken from bone marrow aspirates from iliac crest (BM) of healthy donors or from the caput femoris (HIP) of elderly patients that received femoral head prosthesis.

Project description:Subchondral bone samples from six patients who underwent primary total hip arthroplasty (three ONFH patients and three patients in control group with femoral neck fracture) were obtained.

Methylation Pattern of Human Mesenchymal Stromal Cells

Project description:In this study, we have analyzed DNA methylation changes upon long-term culture and aging of MSC by using the HumanMethylation27 BeadChip assessing 27,578 unique CpG sites. Cells were taken from bone marrow aspirates from iliac crest (BM) of healthy donors or from the caput femoris (HIP) of elderly patients that received femoral head prosthesis.Overall, the methylation pattern was maintained throughout both long-term culture and aging but highly significant differences were observed at specific CpG sites. Notably, methylation changes in MSC were related in long-term culture and aging in vivo.
