Morphine is used to treat pain in several medical conditions including cancer. Here we show that morphine, in a concentration typical of that observed in patients' blood, stimulates human microvascular endothelial cell proliferation and angiogenesis in vitro and in vivo. It does so by activating mitogen-activated protein kinase/extracellular(More)
A culture of human blood outgrowth endothelial cells (BOECs) was established from a sample of peripheral blood and was transfected using a nonviral plasmid carrying complementary DNA for modified human coagulation factor VIII (B domain deleted and replaced with green fluorescence protein). BOECs were then chemically selected, expanded, cryopreserved, and(More)
erating rat liver under specific experimental conditions has been evaluated by autora diographic and biochemical methods. A rapid disappearance of the labeled thymidine from the blood in the 1st 10 mm was accompanied by a rapid incorporation of the radio activity into the acid-soluble fraction and DNA of the liver cells. Two mm after ad ministration, label(More)
Fourteen new colorectal cancer cell lines were developed as part of a tumor acquisition, propagation, and preservation program for biotherapy. Fifty-six specimens were received. Nine cell lines were generated from biopsies; seven of these cell lines were from metastatic lesions. Five additional cell lines were developed from xenografts grown in nude mice.(More)
We have mutated the type I cellular retinoic acid binding protein (CRABP-I), individually at the Arg131 (into Ala) and the Tyr 133 (into Phe) residues which have been predicted to make direct contact with retinoic acid (RA) based upon previous structural studies. The RA-binding affinities of these mutants are examined and their biological effects on RA(More)
A methodology for rapid isolation of neuroblastoma cells from marrow with metastatic neuroblastoma cells was developed using a cocktail of five antibodies and magnetic microspheres coated with secondary antibodies. Cells bound to microspheres were released by brief exposure to chymopapain, followed by repeated culture of released cells in serum-supplemented(More)
