OBJECTIVE Preinjection gelfoam embolization during percutaneous vertebroplasty (PVP) has been thought alternative technique to prevent the leakage of bone cement. The goal of this study was to evaluate whether the gelfoam techniques are useful to reduce bone cement leakage. METHODS Total 100 PVPs of osteoporotic spine compression fractures were performed by 1 spine surgeon who experienced mor...

Vessel anastomosis is important in tumor angiogenesis as well as for vascularization therapy for ischemia and other diseases. We report here the development of a color-coded imaging model that can visualize the anastomosis between blood vessels of red fluorescent protein (RFP)-expressing vessels in vascularized Gelfoam® previously transplanted into RFP transgenic mice and then re-transplanted i...

Conventional methods of endothelial cell culture on monolayers and beads require enzymatic digestion, traumatic scraping, or centrifugation to transfer cells to other experimental systems. Gelfoam, a porous gelatin block, not only supports the growth of bovine pulmonary artery endothelial cells but also allows the rapid transfer of cell-laden blocks from one experimental system to another with ...

Stomach cancer carcinomatosis peritonitis (SCCP) is a recalcitrant disease. The goal of the present study was to establish an in vitro-in vivo-like imageable model of SCCP to develop cell-cycle-based therapeutics of SCCP. We established 3-D Gelfoam® histoculture and tumor-sphere models of SCCP. FUCCI-expressing MKN-45 stomach cancer cells were transferred to express the fluorescence ubiquinized...

The purpose of this investigation was to use a quantitative technique to evaluate the hemostatic properties of gelfoam and thrombin. To accomplish this, blood was drawn from dogs, labeled in vitro with 5tCr and then reinjected back into the donor dogs. When pulp exposures were made, all blood shed from the site was collected in 30 second intervals to allow calculation of the rate of bleeding. T...

Ziel: Evaluation von Effizienz und Sicherheit der Anwendung von Gelfoam zum Verschluss großlumiger transhepatischer und transsplenischer Zugangswege bei Kindern. Material und Methode: Zwischen Januar 2012 und Mai 2013 wurden 8 perkutane transhepatische und 3 perkutane transsplenische Zugangswege bei pädiatrischen Patienten mittels Gelfoam verschlossen. Um die Effektivität und Sicherheit dieses ...

We have previously studied mouse whisker follicles in Gelfoam® histoculture to determine the role of nestin-expressing plutipotent stem cells, located within the follicle, in the growth of the follicular sensory nerve. Long-term Gelfoam® whisker histoculture enabled hair follicle nestin-expressing stem cells to promote the extensive elongation of the whisker sensory nerve, which contained axon ...

Twelve mongrel dogs were randomly allocated into two groups using matched paired-design. Catheters were inserted into the hepatic artery, hepatic vein and the femoral vein, respectively. In the first group, gelfoam supplemented with mitomycin C (MMC) was injected into the hepatic artery, whereas the second group received a hepatic arterial injection of MMC solution alone. Simultaneous blood sam...

INTRODUCTION In the last decade, there has been an increasing use of biomaterial patches in the regeneration of traumatic tympanic membrane perforations. The major advantages of biomaterial patches are to provisionally restore the physiological function of the middle ear, thereby immediately improving ear symptoms, and act as a scaffold for epithelium migration. However, whether there are addit...

We have previously demonstrated that hair follicles contain nestin-expressing pluripotent stem cells that can effect nerve and spinal cord repair upon transplantation. In the present study, isolated whisker follicles from nestin-driven green fluorescent protein (ND-GFP) mice were histocultured on Gelfoam for 3 weeks for the purpose of transplantation to the spinal cord to heal an induced injury...
