TL;DR: Data suggest that PC play an important role in angiogenesis through secretion of an FGF-like molecule.

TL;DR: Enhanced Wnt/&bgr;-catenin signaling in ABCG2+ MPCs drives a phenotype of persistent microvascular dysfunction, abnormal angiogenesis, and subsequent exacerbation of bleomycin-induced fibrosis, which may account in part for the aberrant microvessel function and remodeling that are associated with chronic lung diseases.
Journal ArticleDOI
Fibrous hamartoma of infancy: An ultrastructural study
TL;DR: Electron microscopy seems to confirm the hamartomatous nature of fibrous hamartomas of infancy, and the lesion appears to recapitulate the formation of blood vessels and fat, as seen in fetal tissues.
Journal ArticleDOI
Pericytes of Newly Formed Vessels in Experimental Subretinal Neovascularization
TL;DR: Pericytes are involved in maturation of the endothelial cells that form subretinal new vessels that form new vessels in a primate model induced by intense laser photocoagulation.
Journal ArticleDOI
Angiogenesis from mononuclear cells in thrombi.
TL;DR: In blood vessels with on unimpaired intimal layer, angiogenesis by invasion of capillaries occurs at an earlier date than capillary formation by mononuclear cells.

THE USE OF LEAD CITRATE AT HIGH pH AS AN ELECTRON-OPAQUE STAIN IN ELECTRON MICROSCOPY
TL;DR: The stain reported here differs from previous alkaline lead stains in that the chelating agent, citrate, is in sufficient excess to sequester all lead present, and is less likely to contaminate sections.
Journal ArticleDOI
Staining of Tissue Sections for Electron Microscopy with Heavy Metals
TL;DR: Certain hitherto unobserved details are revealed and some sort of specificity exists, although the factors involved are not yet understood.
Journal ArticleDOI
Cytochemistry and electron microscopy. The preservation of cellular ultrastructure and enzymatic activity by aldehyde fixation.
TL;DR: A postfixation in osmium tetroxide, even after long periods of storage, developed an image that—notable in the case of glutaraldehyde—was largely indistinguishable from that of tissues fixed under optimal conditions with osmia tetroxides alone.
Journal ArticleDOI
A method for staining epoxy sections for light microscopy.
TL;DR: A technique for staining sections of osmium-fixed, epoxy-embedded tissues for light microscopy using aqueous toluidine blue at pH 11.1 and does not require prior removal of embedding medium, which permits better utilization of the full resolving power of the light microscope.
Journal ArticleDOI
The initiation of cell division in a contact-inhibited mammalian cell line.
TL;DR: The sequence of event suggests that regulation of RNA synthesis is the means by which contact inhibition controls cell division, and therefore DNA synthesis and cell division are controlled.
