TLDR
Investigation of flk-1 receptor tyrosine kinase mRNA expression by in situ hybridization analysis revealed specific association with endothelial cells at all stages of mouse development, suggesting a major role of this ligand-receptor signaling system in vasculogenesis and angiogenesis.About:

Isolation of putative progenitor endothelial cells for angiogenesis.
Takayuki Asahara,Toyoaki Murohara,Alison Sullivan,Marcy Silver,Rien van der Zee,Tong Li,Bernhard Witzenbichler,Gina C. Schatteman,Jeffrey M. Isner +8 more
TL;DR: It is suggested that EC progenitors may be useful for augmenting collateral vessel growth to ischemic tissues (therapeutic angiogenesis) and for delivering anti- or pro-angiogenic agents, respectively, to sites of pathologic or utilitarianAngiogenesis.
Journal ArticleDOI
Angiogenesis in cancer, vascular, rheumatoid and other disease
TL;DR: Think of the switch to the angiogenic phenotype as a net balance of positive and negative regulators of blood vessel growth, which may dictate whether a primary tumour grows rapidly or slowly and whether metastases grow at all.
Journal ArticleDOI
The biology of vascular endothelial growth factor
TL;DR: The establishment of a vascular supply is required for organ development and differentiation as well as for tissue repair and reproductive functions in the adult.

TL;DR: It is reported that formation of blood vessels was abnormal, but not abolished, in heterozygous VEGF-deficient (VEGF+/-) embryos, generated by aggregation of embryonic stem (ES) cells with tetraploid embryos (T-ES)16,17, and even more impaired in homozygous D1-VEGF- deficient (VDGF-/-) T-ES embryos, resulting in death at mid-gestation.

TL;DR: The generation of mice deficient in Flk-1 by disruption of the gene using homologous recombination in embryonic stem (ES) cells is reported, indicating that FlK-1 is essential for yolk-sac blood-island formation and vasculogenesis in the mouse embryo.

Single-step method of RNA isolation by acid guanidinium thiocyanate-phenol-chloroform extraction
TL;DR: A new method of total RNA isolation by a single extraction with an acid guanidinium thiocyanate-phenol-chloroform mixture is described, providing a pure preparation of undegraded RNA in high yield and can be completed within 4 h.

A technique for radiolabeling DNA restriction endonuclease fragments to high specific activity
TL;DR: A technique for conveniently radiolabeling DNA restriction endonuclease fragments to high specific activity is described, and these "oligolabeled" DNA fragments serve as efficient probes in filter hybridization experiments.
A technique for radiolabeling DNA restriction endonuclease fragments to high specific activity
TL;DR: In this article, a technique for conveniently radiolabeling DNA restriction endonuclease fragments to high specific activity is described, where DNA fragments are purified from agarose gels directly by ethanol precipitation and are then denatured and labeled with the large fragment of DNA polymerase I, using random oligonucleotides as primers.

Enzymatic amplification of beta-globin genomic sequences and restriction site analysis for diagnosis of sickle cell anemia.

TL;DR: Two new methods were used to establish a rapid and highly sensitive prenatal diagnostic test for sickle cell anemia, using primer-mediated enzymatic amplification of specific beta-globin target sequences in genomic DNA, resulting in the exponential increase of target DNA copies.

Ligand: a versatile computerized approach for characterization of ligand-binding systems.
Peter J. Munson,David Rodbard +1 more
TL;DR: This approach provides two major advantages compared with other available methods: it uses an exact mathematical model of the ligand-binding system, thereby avoiding the possible biases introduced by several commonly used approximations and it uses a statistically valid, appropriately weighted least-squares curve-fitting algorithm with objective measurement of goodness of fit.
