Mice lacking the enzyme MMP14 in bone-forming cells initially gained bone mass when young, but later developed severe bone loss driven by immune cells.Mice lacking the enzyme MMP14 in bone-forming cells initially gained bone mass when young, but later developed severe bone loss driven by immune cells.
In bone marrow stem cells linked to senile osteoporosis, lamin B1 loss triggered a form of cell death that disrupted mitochondria and impaired bone formation.In bone marrow stem cells linked to senile osteoporosis, lamin B1 loss triggered a form of cell death that disrupted mitochondria and impaired bone formation.
Experiments in mice whose ovaries had been removed linked ceruloplasmin deficiency to higher bone mass at the tissue level.Experiments in mice whose ovaries had been removed linked ceruloplasmin deficiency to higher bone mass at the tissue level.
In a mouse model of osteoporosis, silencing a gene or inhibiting its protein reduced the activity of cells that break down bone.In a mouse model of osteoporosis, silencing a gene or inhibiting its protein reduced the activity of cells that break down bone.
Experiments linked reduced bone formation to impaired sugar breakdown, while genetic changes that enhanced the process improved bone-forming cell function in aged mice.Experiments linked reduced bone formation to impaired sugar breakdown, while genetic changes that enhanced the process improved bone-forming cell function in aged mice.
In a four-week mouse experiment, a bone-building hormone enlarged the spaces housing bone cells, while a drug that slows bone breakdown stabilised their local structure.In a four-week mouse experiment, a bone-building hormone enlarged the spaces housing bone cells, while a drug that slows bone breakdown stabilised their local structure.
