Six decades ago, Friedenstein and coworkers published a series of seminal papers identifying a cell population in bone marrow with osteogenic potential, now referred to as mesenchymal stem cells (MSCs). This work was also instrumental in establishing the identity of hematopoietic stem cell and the identification of skeletal stem/progenitor cell (SSPC) populations in various skeletal compartments. In recognition of the centenary year of Friedenstein's birth, I review key aspects of his work and discuss the evolving concept of the MSC and its various euphemisms indorsed by changing paradigms in the field. I also discuss the recent emphasis on MSC stromal quality attributes and how emerging data demonstrating a mechanistic link between stromal and stem/progenitor functions bring renewed relevance to Friedenstein's contributions and much needed unity to the field.

Hypertension, commonly known as high blood pressure, is a significant health issue that increases the risk of cardiovascular diseases, stroke, and renal failure. This condition broadly encompasses both primary and secondary forms. Despite extensive research, the underlying mechanisms of systemic arterial hypertension-particularly primary hypertension, which has no identifiable cause and is affected by genetic and lifestyle agents-remain complex and not fully understood.

Bone marrow mesenchymal stromal cells (BM-MSCs) are integral components of the bone marrow microenvironment, playing a crucial role in supporting hematopoiesis. Recent studies have investigated the potential involvement of BM-MSCs in the pathophysiology of acute lymphoblastic leukemia (ALL). However, the exact contribution of BM-MSCs to leukemia progression remains unclear because of conflicting findings and limited characterization.

Bone defects are difficult to treat clinically and most often require bone grafting for repair. However, the source of autograft bone is limited, and allograft bone carries the risk of disease transmission and immune rejection. As tissue engineering technology advances, bone replacement materials are playing an increasingly important role in the treatment of bone defects.

Esophageal squamous cell carcinoma (ESCC) is prone to metastasis and is a leading cause of mortality. The cytoskeleton is closely related to cell morphology and movement; however, little research has been conducted on ESCC metastasis. In this study, we found that the anchoring filament protein ladinin 1 (LAD1) specifically binds to LINC01305 for co-regulating the level of modulating cortactin proteins (CTTN) and neuronal Wiskott-Aldrich syndrome protein (N-WASP) phosphorylation, which mediates cytoskeletal reorganization and affects the metastasis of ESCC cells.

Background: Calcific aortic valve disease is the pathological remodeling of valve leaflets. The initial steps in valve leaflet osteogenic reprogramming are not fully understood. As TERT (telomerase reverse transcriptase) overexpression primes mesenchymal stem cells to differentiate into osteoblasts, we investigated whether TERT contributes to the osteogenic reprogramming of valve interstitial cells.
