Purpose Of Review: Human induced pluripotent stem cells (iPSCs) are an attractive source to generate in-vitro-derived blood for use as transfusable and reagent red cells. We review recent advancements in the field and the remaining limitations for clinical use.
Recent Findings: For iPSC-derived red blood cell (RBC) generation, recent work has optimized culture conditions to omit feeder cells, enhance red cell maturation, and produce cells that mimic fetal or adult-type RBCs. Genome editing provides novel strategies to improve cell yield and create designer RBCs with customized antigen phenotypes.
Summary: Current protocols support red cell production that mimics embryonic and fetal hematopoiesis and cell yield sufficient for diagnostic RBC reagents. Ongoing challenges to generate RBCs for transfusion include recapitulating definitive erythropoiesis to produce functional adult-type cells, increasing scalability of culture conditions, and optimizing high-density manufacturing capacity.

Introduction: Anticoagulant therapy is critical for venous thromboembolism (VTE) management, though bleeding remains a major concern, ranging from mild to fatal events. This study aimed to assess the predictive value of cytokines for major bleeding in patients with acute pulmonary embolism (PE).
Methods: In this prospective, observational study, patients aged ≥ 18 years with acute PE were enrolled from April 2021 to September 2022 and followed for 30 days.

Anemia of prematurity (AOP) is a multifactorial condition associated with congenital iron deficiency, low erythropoietin levels, a short lifespan of red blood cells, and iatrogenic blood loss. AOP is a common complication in premature infants that can adversely affect growth, development, and long-term neurocognitive outcomes. To standardize the diagnosis and treatment of AOP, the Neonatal Clinical Practice Guidelines Expert Committee and the Neonatal Evidence-Based Medicine Group of the Commission of Neonatal Medicine of the Cross-Strait Medical and Health Exchange Association, along with the Editorial Office of the , have developed the "Clinical practice guidelines for the diagnosis and treatment of anemia of prematurity (2025)", based on the World Health Organization's handbook for guideline development and the formulation/revision principles of Chinese clinical practice guidelines.

Background: The pathogenesis of sepsis is thought to be linked to a dysregulated immune response, particularly that involving neutrophils. We have developed a granulocyte adsorption column as a "decoy organ," which relocates the massive inflammation in organs in the body to a blood purification column. This study was conducted to assess the safety and experimental effectiveness of granulocyte monocyte adsorption apheresis-direct hemoperfusion (G1-DHP) in the treatment of patients with sepsis, using a prospective, multicenter design.

The rise of antimicrobial resistance has made necessary the increase of the antibacterial arsenal against multidrug-resistant bacteria. In this context, colistin has re-emerged as a first-line antibiotic in critical situations despite its nephro- and neuro- toxicity at peripheral level. However, the mechanism underlying its toxicity remains unknown, particularly in relation to the central nervous system (CNS).

Cytokinins are plant hormones that regulate cell growth and differentiation. In particular, zeatin (ZTN) delays cellular senescence of human fibroblasts and keratinocytes and exhibits anticancer activity. Chemotherapy-induced anemia is a major side effect of anticancer therapy secondary to premature senescence of red blood cells (RBCs).
