PURPOSE OF REVIEW: Despite significant improvements in the management of patients undergoing allogeneic stem cell transplantation, including anticytomegalovirus (CMV) prophylaxis and treatment, clinical handling of CMV infection remains challenging in the light of high morbidity and mortality rates. Thus, novel strategies and agents to control CMV infection and disease will be discussed. RECENT FINDINGS: Novel assays to quantify viral load and detect antiviral resistance mechanisms on the basis of next-generation sequencing have been described and will help to earlier and more effectively control CMV infection...

PURPOSE OF REVIEW: Fibroblast growth factor (FGF) signaling activates many bone marrow cell types, including various stem cells, osteoblasts, and osteoclasts. However, the role of FGF signaling in regulation of normal and leukemic stem cells is poorly understood. This review highlights the physiological roles of FGF signaling in regulating bone marrow mesenchymal and hematopoietic stem and progenitor cells (MSPCs and HSPCs) and their dynamic microenvironment. In addition, this review summarizes the recent studies which provide an overview of FGF-activated mechanisms regulating physiological stem cell maintenance, self-renewal, and motility...
