Summary
Elevated circulating endothelial cells (ECs) may indicate systemic acute graft-versus-host disease (aGVHD) following allogeneic bone marrow transplantation. Monitoring ECs could help assess endothelial injury during aGVHD progression.
Area of Science:
- Immunology
- Hematology
- Transplantation Medicine
Background:
- Circulating endothelial cells (ECs) are recognized biomarkers of endothelial injury.
- Endothelial injury is a known complication associated with graft-versus-host disease (GVHD).
Purpose of the Study:
- To investigate the potential association between circulating ECs and systemic acute graft-versus-host disease (aGVHD).
Main Methods:
- Mice underwent irradiation and received T-cell-depleted bone marrow cells, with or without splenocytes.
- Circulating ECs and lymphocytes were quantified using flow cytometry.
- Endothelial morphology was assessed via light and transmission electron microscopy.
- Cyclosporine (CSA) was administered to evaluate its effect on endothelial injury.
Main Results:
- Circulating ECs showed an initial peak on day 5 post-irradiation.
- Allogeneic transplant recipients developed aGVHD by day 7, with a secondary EC peak observed on day 9 correlating with disease progression.
- CSA administration reduced or prevented further endothelial injury.
Conclusions:
- Circulating EC levels may serve as a potential indicator for systemic aGVHD.
- The findings suggest a link between endothelial cell dynamics and the development of aGVHD.

01:01Regulation of Hematopoietic Stem Cells
All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...
01:19Clinical Applications of Epidermal Stem Cells
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own EpiSCs...
01:21Cytotoxic Edema: Pathophysiology
Cytotoxic edema is a form of cerebral edema characterized by intracellular swelling of neurons, astrocytes, and other glial cells. It develops when the mechanisms responsible for maintaining ionic gradients across the cell membrane become impaired. Under normal physiological conditions, the sodium–potassium ATPase actively transports sodium ions out of the cell and potassium ions into the cell, preserving osmotic balance and enabling electrical signaling. This pump requires a continuous supply...
