In Vivo:
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% EtOH 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (5.11 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL EtOH stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% EtOH 90% Corn Oil
Solubility: ≥ 2.5 mg/mL (5.11 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Taking 1 mL working solution as an example, add 100 μL EtOH stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

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.

Apoptosis
Apoptosis, also called programmed cell death, is generally characterized by distinct morphological characteristics.

TUNEL staining for apoptotic DNA fragmentation
TUNEL staining detects DNA strand breaks by using terminal deoxynucleotidyl transferase to add labeled nucleotides to exposed 3′-OH DNA termini, generating either microscopic staining in fixed cells or tissue sections, or fluorescence/cytometric signal in cell suspensions. TUNEL positivity reflects DNA fragmentation but should not be interpreted alone as definitive apoptosis, because TUNEL can also label necrotic, autolytic, mechanically damaged, or DNA-repair-associated DNA breaks.

Cell Cytotoxicity Assay
Cytotoxicity assays are usually based on the assessment of cell membrane damage, which can also be indirectly detected by measuring cell viability. Detection methods include MTT assay, CKK-8 assay, LDH assay and ATP assay, etc.

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

Annexin V plus membrane-impermeant dye apoptosis staining
Annexin V-based apoptosis assays rely on the detection of phosphatidylserine (PS) externalization from the inner leaflet of the plasma membrane to the outer leaflet, an early biochemical hallmark of apoptosis. Fluorescently labeled Annexin V binds PS in a calcium-dependent manner, enabling identification of early apoptotic cells by flow cytometry or fluorescence microscopy. When combined with a membrane-impermeant DNA-binding dye (e. g. , propidium iodide), this approach allows discrimination between viable (Annexin V−/dye−), early apoptotic (Annexin V+/dye−), and late apoptotic or necrotic (Annexin V+/dye+) cell populations by assessing membrane integrity and PS exposure.
-
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.

Apoptosis Solutions
Apoptosis is a regulated, generally non-lytic cell-death pathway that removes unwanted, damaged, infected, or abnormal cells through coordinated morphological changes, caspase activation, DNA fragmentation, and membrane remodeling. The intrinsic apoptosis pathway is controlled mainly by mitochondrial outer membrane permeabilization, BCL-2 family proteins, cytochrome c release, apoptosome formation, caspase-9 activation, and downstream executioner caspase-3/7 activation. The extrinsic apoptosis pathway is initiated by death receptors such as Fas, TNFR, and TRAIL receptors, which recruit adaptor proteins and activate caspase-8 before engaging executioner caspases or mitochondrial amplification through BID cleavage. Apoptosis is linked to many phenotypes, including cancer cell killing, tissue homeostasis, immune regulation, neurodegeneration, infection response, and treatment-induced cytotoxicity; unresolved questions include how apoptosis interacts with necroptosis, pyroptosis, ferroptos

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.
