A 3D bone marrow niche that reproduces megakaryocyte differentiation and ex vivo platelet production from hematopoietic progenitors and iPSCs of thrombocytopenic patients predicts individual response to Eltrombopag accurately.
OGT-mediated protein O-GlcNAcylation balances osteogenic versus adipogenic differentiation and controls hematopoietic niche function of bone marrow stromal cells.

Endotoxemia recruits fast-acting anti-inflammatory innate myeloid progenitors from bone marrow into regional lymphatics through release of pre-formed Ccl19 secondary to NF-κB-independent, Traf6/IκB kinase-dependent signaling.

Diet-induced obesity in mice led to a duration of diet-dependent bone marrow adipocyte whitening, which drove monocyte expansion and skewing towards a tissue-invasive phenotype, likely contributing to ensuing tissue infiltration that accompanies obesity and diabetes.
The anti-cancer or lifespan extension properties of a novel genetically engineered hematopoietic blood system could be transferred horizontally in mice, which suggests a new direction of biomedical research for anti-aging/antidisease.

Obese Ksr2 mutant mice have increased trabecular bone but decreased marrow adiposity and are more prone to fractures, thus providing a useful model to understand how stem cells can be manipulated to produce bone at the expense of marrow fat.

Developing long bones contain distinct mesenchymal stem-cell populations derived from mesoderm and neural crest, which have specialized functions in skeleton formation and the establishment of the hematopoietic stem-cell niche, respectively.
PDGFRα+ Sca-1+ bone marrow stromal/stem cells in whole bone marrow grafts can trigger the onset of autoimmune-related fibrosis in a mouse model of scleroderma.
A three-dimensional investigation of extinct-tetrapod limbs shows that even though bone elongation and blood-cell production are intimately related to mammal long bones, these functions actually appeared successively in tetrapod evolution.
