The first hematopoietic and endothelial progenitors are derived from a common embryonic precursor termed the hemangioblast. The genetic cascades that regulate the differentiation of the hemangioblast to hematopoietic and endothelial cells are largely unknown. In general, much of embryonic development is coordinately regulated by temporal and spatial expression of transcription factors, such as ...
OBJECTIVE In vivo and in vitro stem cell differentiation into endothelial cells is a promising area of research for tissue engineering and cell therapy. MATERIALS AND METHODS We induced human mesenchymal stem cells (MSCs) to differentiate to endothelial cells that had the ability to form capillaries on an extracellular matrix (ECM) gel. Thereafter, the differentiated endothelial cells at earl...
Within the vascular endothelial growth factor (VEGF) family of five subtypes, VEGF165 secreted by endothelial cells has been identified to be the most active and widely distributed factor that plays a vital role in courses of angiogenesis, vascularization and mesenchymal cell differentiation. Hair follicle stem cells (HFSCs) can be harvested from the bulge region of the outer root sheath of the...
Endothelial-like differentiation of dendritic cells (DCs) is an interesting and significant phenomenon, which is worth further investigation. Here, we show that the tumor microenvironment derived from the supernatant of the SW620 human colon adenocarcinoma cell line and colon adenocarcinoma tissue homogenate can promote immature DCs (iDCs) to differentiate from the DC pathway toward endothelial...
Stem cells are undifferentiated biological cells that can differentiate into more specialized cells and divide (through mitosis) to produce more stem cells (self-renew). In mammals, there are two broad types of stem cells: embryonic stem cells, which are isolated from the inner cell mass of blastocysts, and adult stem cells, which are found in various tissues. Mesenchymal stem cells (MSCs) are ...
Transforming growth factor β1 (TGFβ1) is shown here to be required for yolk sac haematopoiesis and endothelial differentiation. Mice with a targeted mutation in the TGFβ1 gene were examined to determine the cause of prenatal lethality, which occurs in 50% of homozygous TGFβ1 null (TGFβ1−/−) conceptions. 50% of TGFβ1−/− and 25% of TGFβ1+/− conceptuses were found to die at around 10.5 dpc. The pr...
In our previous study, 4-hexylresorcinol (4HR) increased the expression level of vascular endothelial growth factor in human umbilical vein cells (HUVECs) via transforming factor-β1 (TGF-β1)-mediated pathway. Endoplasmic reticulum (ER) and mitochondrial stress is a positive regulator cellular differentiation. As TGF-β1 master for differentiation, 4HR treatment may increase ER stress. this HUVEC...
Leaf Veins The leaf vein is the “vascular system” in plants. In article 2201220 by Kelvin W. K. Yeung, Xin Zhao, and co-workers, a leaf-vein micropattern engraved on PGLADMA polymer membrane, serving as “running tracks” for vascular endothelial cells to facilitate hierarchical functional reconstruction. membrane can induce cell differentiation, vasculature reconstruction, vessel maturation.
