Outcomes in acute myeloid leukemia (AML) remain poor due to high rates of relapse. Thus, there is an urgent unmet medical need for new therapies that can more effectively kill the leukemia stem cells (LSC) and recently recognized preleukemic hematopoietic stem cells (preL-HSC) that can drive relapsed disease. In order to develop such therapies, a better understanding of the biology of these stem cell populations is required. The best functional assays for stem cells are xenotransplantation models using immunodeficient mouse recipients. Here, we present evidence of the clinical validity of such models for studying the biology of AML stem cells and propose a new paradigm for the development of LSC-targeted agents and biomarker tools for patient selection.

To further evaluate the effects of lymphocyte immunotherapy (LIT) for the treatment of RPL patients this study aimed to utilize this type of treatment in RPL patients with positive antinuclear antibodies (ANA) in comparison to ANA-negative RPL women. To this aim, 84 ANA-positive, 114 ANA negative, and 50 healthy pregnant women were recruited. To examine the frequency of cells before and after LIT, flowcytometry technique was employed.

Silk fibroin (SF) hydrogels are widely used in three-dimensional (3D) cell culture and tissue repair. Despite their importance, few studies have focused on regulating their degradation and further revealing the effects of the degradation process on encapsulated cell behaviors. Herein, SF hydrogels with equivalent initial properties and different degradation rates were prepared by adjusting the ratios between the hydrogel-encapsulated normal SF microspheres (MS) and enzyme-loaded SF microspheres (MS).

A growing body of evidence suggest that the stem cell antigen-1 expressing (Sca-1) cells in the heart may be the cardiac endothelial stem/progenitor cells. Their endothelial cell (EC) functions, and their role in RV physiology and pathophysiology of right heart failure (RHF) remains poorly defined. This study investigated EC characteristics of rat cardiac Sca-1 cells, assessed spatial distribution and studied changes in Sca1 cells during RV remodelling in monocrotaline (MCT) model of pulmonary hypertension and RV remodeling.

Birth is one of the most important life events for animals. However, its significance in the developmental process is not fully understood. Here, we found that birth-induced alteration of glutamine metabolism in radial glia (RG), the embryonic neural stem cells (NSCs), is required for the acquisition of quiescence and long-term maintenance of postnatal NSCs.

Exogenous neural stem cells (NSCs) have great potential to reconstitute damage spinal neural circuitry. However, regulating the metabolic reprogramming of NSCs for reliable nerve regeneration has been challenging. This report discusses the biomimetic dextral hydrogel (DH) with right-handed nanofibers that specifically reprograms the lipid metabolism of NSCs, promoting their neural differentiation and rapid regeneration of damaged axons.
