The evolving view of the hematopoietic stem cell niche.
Hematopoietic stem cells (HSCs) reside in specialized microenvironments known as niches. The niche is essential to support HSC function and to maintain a correct balance between self-renewal and differentiation. Recent advances...

Geospatial distributions reflect temperatures of linguistic features.
Quantifying the speed of linguistic change is challenging because the historical evolution of languages is sparsely documented. Consequently, traditional methods rely on phylogenetic reconstruction. Here, we propose a...

Golan K, Singh AK et al.1 describe how mitochondrial transfer from hematopoietic stem cells (HSCs) to bone marrow (BM) mesenchymal stem cells (MSCs) helps to regenerate the stroma and its capacity to sustain hematopoietic...

Impact of GAN-based lesion-focused medical image super-resolution on the robustness of radiomic features.
Robust machine learning models based on radiomic features might allow for accurate diagnosis, prognosis, and medical decision-making. Unfortunately, the lack of standardized radiomic feature extraction has hampered their...

Chaotic-Integrable Transition in the Sachdev-Ye-Kitaev Model.
Quantum chaos is one of the distinctive features of the Sachdev-Ye-Kitaev (SYK) model, N Majorana fermions in 0+1 dimensions with infinite-range two-body interactions, which is attracting a lot of interest as a toy model for...

Because hematopoietic stem cells (HSCs) were found to require a bone marrow (BM) habitat for long-term function, many studies have attempted to dissect key cellular and molecular interactions between HSCs and their BM...

Cellular Heterogeneity of Mesenchymal Stem/Stromal Cells in the Bone Marrow
Mesenchymal stem/stromal cells (MSCs) are present in various body tissues and help in maintaining homeostasis. The stemness of MSCs has been evaluated in vitro. In addition, analyses of cell surface antigens and gene expression...

Neuronal regulation of bone marrow stem cell niches.
The bone marrow (BM) is the primary site of postnatal hematopoiesis and hematopoietic stem cell (HSC) maintenance. The BM HSC niche is an essential microenvironment which evolves and responds to the physiological demands of...

In this issue of Blood, Zhao et al use a humanized mouse model to investigate the mechanisms driving daily oscillations in circulating human and murine leukocytes.1 In the same mice, they find human and murine circulating...

Microenvironmental contributions to hematopoietic stem cell aging.
Hematopoietic stem cell (HSC) aging was originally thought to be essentially an HSC-autonomous process, which is the focus of another review in the same issue of Haematologica However, studies on the microenvironment that...
