Generation of Self‐Organizing Macrovascular Constructs by Bioprinting Human iPSC‐Derived Mesodermal Progenitor Cells

Advanced Science
Vascularization remains a major obstacle in tissue engineering. Here, we introduce a bioprinting strategy to generate centimeter‐scale, self‐organizing “mother vessel” constructs from iPSC‐derived hiMPCs.

Engineering Ultrastable Intrinsic Radicals: Graphene Quantum Dots With NIR‐II Emission for Dynamic Deep‐Tissue Bioimaging

Advanced Science, EarlyView.
Stable radicals are attractive for photonic and quantum information technologies but are often limited by instability. We stabilize intrinsic radicals in graphene quantum dots via 2D polymerization of perylene derivatives, where bilayer defect confinement suppresses quenching (100–500 K).

SPONTANEOUS SUBUNGUAL HEMORRHAGES IN A PATIENT WITH METABOLIC SYNDROME AND HYPERHOMOCYSTEINEMIA: A CASE REPORT

Juvenis Scientia, 2020
Spontaneous (nontraumatic) subungual hemorrhages are not uncommon, however, given their low specificity, they usually do not become a reason for an in-depth investigation in the absence of other symptoms of diseases requiring diagnostics.

Immunohistochemical Assessment of Mast Cells and Small Blood Vessels in Dentigerous Cyst, Odontogenic Keratocyst, and Periapical Cyst [PDF]

Advanced Pharmaceutical Bulletin, 2015
Purpose: The aim of this study was to verify the density of mast cells (MCs) and microvessels in odontogenic cysts. Furthermore, the correlation between MCs and microvessels was evaluated to assess the contribution of MCs to angiogenesis and growth of ...

Biomimetic Scaffold‐Based 3D Models for Decoding Cancer Biology and Advancing Therapy

Advanced Science, EarlyView.
A timeline of the research history of 3D biomimetic scaffold materials and platforms. With advances in biomimetic materials and 3D scaffold technologies, their functional scope has expanded from mimicking basic physical and biochemical properties to increasingly replicating complex pathophysiological processes.

Arterial supply and morphological characteristics of sympathetic neurons in the human superior cervical ganglion

Frontiers in Neuroanatomy
The aim of this study was the micromorphological analysis of the distribution of microvessels, mast cells and ganglionic neurons in two parts, proximal and distal of the human superior cervical sympathetic ganglions (SCSGs).

Precise Cerebral Vascular Atlas in Stereotaxic Coordinates of Whole Mouse Brain

Frontiers in Neuroanatomy, 2017
Understanding amazingly complex brain functions and pathologies requires a complete cerebral vascular atlas in stereotaxic coordinates. Making a precise atlas for cerebral arteries and veins has been a century-old objective in neuroscience and ...

Evans blue dye-enhanced imaging of the brain microvessels using spectral focusing coherent anti-Stokes Raman scattering microscopy. [PDF]

PLoS ONE, 2017
We performed dye-enhanced imaging of mouse brain microvessels using spectral focusing coherent anti-Stokes Raman scattering (SF-CARS) microscopy. The resonant signals from C-H stretching in forward CARS usually show high background intensity in tissues ...

Angiophagy: Clearing or Clogging Microvessels? [PDF]

Science Translational Medicine, 2014
The body clears small clots from blood vessels through a process called angiophagy, opening up new approaches to combat cerebral and cardiac microvascular occlusive diseases (Grutzendler et al ., this issue).
