(Submitter supplied) Skeletal aging and disease are associated with a misbalance in the opposing actions of osteoblasts and osteoclasts that are responsible for maintaining the integrity of bone tissues. Here, we show through detailed functional and single-cell genomic studies that intrinsic aging of bona fide mouse skeletal stem cells (SSCs) alters bone marrow niche signaling and skews bone and blood lineage differentiation leading to fragile bones that regenerate poorly. more...

(Submitter supplied) Gene expression profiling using microarray has been limited to profiling of differentially expressed genes at comparison setting since probesets for different genes have different sensitivities. We overcome this limitation by using a very large number of varied microarray datasets as a common reference, so that statistical attributes of each probeset, such as dynamic range or a threshold between low and high expression can be reliably discovered through meta-analysis. more...

(Submitter supplied) To investigate the role of IL1 signaling in hematopoietic aging, we performed droplet-based scRNAseq (10X Genomics) of hematopoietic stem and progenitor cells (LK/LSK) and unfractionated endosteal and central marrow stromal cells (Ter119-/CD45-) from young wild type and young and old wild type and IL1R1-/- C57BL/6 mice.

(Submitter supplied) We performed integrated analyses of hematopoietic stem and progenitor cells as well as bone marrow stromal cells to better understand the underlying mechanisms of blood aging. To determine how the molecular state of multipotent progenitor (MPP) cells change with age we performed transcriptomic analyses of myeloid-biased MPP3 and lymphoid-biased MPP4 populations from young and old mice.

(Submitter supplied) Hematopoietic aging is defined by a loss of regenerative capacity and skewed differentiation from hematopoietic stem cells (HSC) leading to dysfunctional blood production. Signals from the bone marrow (BM) microenvironment dynamically tailor hematopoiesis, but the effect of aging on the niche and the contribution of the aging niche to blood aging still remains unclear. Here, we show the development of an inflammatory milieu in the aged marrow cavity, which drives both niche and hematopoietic system remodeling. more...

(Submitter supplied) To investigate global changes in the structure of the bone marrow niche with age, we performed droplet-based scRNAseq (10X Genomics) of unfractionated endosteal and central marrow stromal cells (Ter119-/CD45-). 8,735 cells passed QC, and hematopoietic clusters of cells were excluded based on marker gene expression, leaving 2359 cells distributed across 9 distinct clusters for final presentation.

(Submitter supplied) The expression of Prx1 has been used as a marker to define the skeletal stem cells (SSC) populations found within the bone marrow and periosteum that contribute to bone regeneration. However, Prx1 expressing SSCs (Prx1-SSCs) are not restricted to the bone compartments, but are also located within the muscle and able to contribute to ectopic bone formation. Little is known however, about the mechanism(s) regulating Prx1-SSCs that reside in muscle and how they participate in bone regeneration. more...
