Protokoll
-
Human pluripotent stem cell endothelial-cell differentiation
Human pluripotent stem cell endothelial differentiation is based on stepwise developmental patterning: early activation of WNT/GSK3β inhibition promotes mesodermal or vascular progenitor entry, followed by endothelial specification using VEGF-related signaling, BMP4, FGF2, Notch modulation, or cAMP depending on the published protocol. Endothelial differentiation is read out by acquisition of CD31, CD34, VE-cadherin/CD144, KDR/VEGFR2, vWF, Tie2, NOS3, acetylated LDL uptake, tube/network formation, barrier function, and in vivo vessel-forming capacity where tested.

Vascular/Branching Fractal Analysis
Vascular/branching fractal analysis quantifies the geometric complexity of vessel trees or vascular networks from segmented 2D images, commonly by converting vessels into binary and/or skeletonized maps and estimating fractal dimension using box-counting or related approaches. Fractal dimension is interpreted as an image-derived readout of vascular branching complexity, space filling, or density, and has been applied to retinal photographs, fluorescein angiography, OCT angiography, capillary perfusion maps, and in vitro Matrigel angiogenesis networks. The assay readout is generated from vessel-positive pixels after image preprocessing, vessel segmentation, binarization, and optional skeletonization; reported outputs include fractal dimension, vessel density, branchpoint density, endpoint density, vessel length density, tortuosity, and generation-based branching metrics when VESGEN-style analysis is used. The biological interpretation is limited to quantitative vascular patterning and s

Endothelial Tube Formation Assay
Endothelial tube formation assay evaluates the ability of endothelial cells to attach, migrate, align, and organize into capillary-like networks when cultured on gelled basement membrane extract or Matrigel; the readout is the morphology and quantity of tube-like networks, which reflects an in vitro endothelial morphogenesis step related to angiogenesis. Basement membrane extract/Matrigel provides laminin-rich extracellular matrix cues that support endothelial differentiation into capillary-like structures, but it can contain biologically active growth factors, so growth-factor-reduced matrix is preferred when testing defined angiogenic stimulators or inhibitors.

Transepithelial/transendothelial electrical resistance assay
TEER measures electrical resistance across epithelial or endothelial monolayers cultured on permeable supports, and the readout reflects ionic conductance through the cell barrier, especially the paracellular pathway regulated by junctional integrity. TEER can be measured without destroying the monolayer and is commonly used before or during transport, permeability, barrier-disruption, and barrier-maturation experiments. TEER values are influenced by biological maturation and technical conditions; reported factors include temperature, medium formulation, passage number, electrode geometry, membrane properties, and junctional length during early monolayer maturation. Therefore, TEER should be interpreted with blank-insert subtraction, area normalization, repeated readings, and, when possible, orthogonal barrier readouts such as FITC-dextran flux or tight-junction staining.
-
Endothelial Cell Migration/Angiogenic Sprouting Assay
Endothelial cell migration and angiogenic sprouting assays are in vitro (and partially ex vivo-adapted) functional models that quantify the ability of endothelial cells to undergo coordinated migration, extracellular matrix invasion, and multicellular organization into capillary-like sprouts in response to pro-angiogenic stimuli such as VEGF, bFGF, or conditioned microenvironments. These assays are used to model early angiogenic events including tip-cell formation, directional migration, and lumen-like sprout extension, which collectively reflect angiogenic activation and vascular morphogenesis processes observed in vivo.
