A 3D Human Bone and Bone Marrow‐on‐a‐Chip Model for In Vitro Bone Remodeling and Immune Cell Maintenance

Advanced Science, EarlyView.
This study presents a human Bone (and Bone Marrow)‐on‐a‐Chip model based on native human bone scaffolds and autologous cells. Dynamic perfusion and sequential cell seeding replicate the physiological bone remodeling process in vitro, enabling the long‐term culture of functional, mature bone marrow immune subpopulations.

A novel role for survivin in erythroblast enucleation

Haematologica, 2012
Background Nucleus free red blood cells are unique to mammals. During their terminal stage of differentiation, mammalian erythroblasts exit the cell cycle and enucleate.

“Membrane‐Guided” Repair Strategy: Precision Delivery of GGT1 Degrader for Targeted Repair and Regeneration of Spinal Cord Neurons

Advanced Science, EarlyView.
This study confirms that GGT1 is a key driver of neuronal ferroptosis following spinal cord injury. We developed NSCm@EA, a biomimetic delivery system coated with neural stem cell membranes, for precise delivery of enocyanin to injured neurons. By combining targeted delivery with ubiquitination degradation mechanisms, this system promotes MGRN1 ...

Stat5 signaling specifies basal versus stress erythropoietic responses through distinct binary and graded dynamic modalities.

PLoS Biology, 2012
Erythropoietin (Epo)-induced Stat5 phosphorylation (p-Stat5) is essential for both basal erythropoiesis and for its acceleration during hypoxic stress. A key challenge lies in understanding how Stat5 signaling elicits distinct functions during basal and ...

Ubiquitination of ACSL4 by Parkin Suppresses Ferroptosis and Rescues Glucocorticoid‐Induced Bone Loss

Advanced Science, EarlyView.
GCs reduce Parkin, leading to ACSL4 accumulation and PUFA‐phospholipid‐driven ferroptosis in BMSCs, which impairs osteogenesis and promotes adipogenesis, causing GIOP. Parkin restoration (via OE‐Parkin or Parkin‐LNP@DSS6) ubiquitinates and degrades ACSL4, inhibiting ferroptosis, rescuing bone formation, and rescues GIOP bone loss.

Diguglielmo syndrome [PDF]

Perspectives In Medical Research, 2017
Acute Erythroid Leukemia (AEL) / Acute Myeloid Leukemia M6 (AML M6) is a rare disorder of hematopoietic system and accounts for 1-3% of acute leukemia and 15% of myeloid leukemia. It is characterized by uncontrolled proliferation of erythroblasts and

Bmi-1 Regulates Extensive Erythroid Self-Renewal

Stem Cell Reports, 2015
Red blood cells (RBCs), responsible for oxygen delivery and carbon dioxide exchange, are essential for our well-being. Alternative RBC sources are needed to meet the increased demand for RBC transfusions projected to occur as our population ages.

Therapeutic Silencing of Tmprss6 Reduces Iron‐Induced Inflammation and Prolongs Survival in MDS Mice

American Journal of Hematology, EarlyView.
ABSTRACT Myelodysplastic syndromes (MDS) are a heterogeneous group of clonal hematopoietic disorders characterized by ineffective hematopoiesis, cytopenias, and an increased risk of progression to acute myeloid leukemia (AML). Despite advances in supportive and targeted therapies, disease‐modifying interventions remain limited.

miR-144/451 represses the LKB1/AMPK/mTOR pathway to promote red cell precursor survival during recovery from acute anemia

Haematologica, 2018
The microRNAs miR-144 and -451 are encoded by a bicistronic gene that is strongly induced during red blood cell formation (erythropoiesis). Ablation of the miR-144/451 gene in mice causes mild anemia under baseline conditions.

Generation of the human erythroblast-derived iPSC line UBTi001-A

Stem Cell Research, 2022
We performed reprogramming of human erythroblasts derived from CD34+ hematopoietic stem / progenitor cells of a healthy donor. CD34+ cells were differentiated in-vitro into a pure population of CD36+ erythroblasts and nucleofected with four episomal ...
