Importantly, once a line is validated, it is a highly scalable source of BMECs: by simply expanding cells in the undifferentiated hPSC stage, one can generate enough hPSC-derived BMECs for tens of thousands of Transwell filters from a single vial of stem cells.
For $5,000, WiCell will send out two tiny vials of human embryonic stem cells to any legitimate scientist who agrees to abide by the institute's restrictions, which include a prohibition on using the cells to create a person.
For production of NSC conditioned medium, a frozen vial of murine neural stem cells (NSCs, a gift from Dr Jeffrey Spees, Department of Medicine, Cardiovascular Research Institute, University of Vermont) was employed.
To test and optimize PET scans of plants, we attached F-phantom vials inside the stem of a sorghum plant (70 DAP), and inside the soil/root compartment at different depths (Additional file 1).
Inset: photographs of the vials containing the solutions of (a) DPPH, (b d) DPPH + with ethanol extract of stem bark 50, 100 and 150 μg/mL.
For the stem phantoms, a small portion of stem was removed with a scalpel blade and the 5 ml vial containing F-fluoride was placed in this cavity (Additional file 1).
Its sole purpose is to guard and nurture vials of precious, potentially life-giving cells, called stem cells, that will soon occupy a squat green Thermos here.
Traditionally, cryopreservation of stem cells has involved a medium containing a cryoprotectant agent, 10% dimethylsulfoxide (DMSO), allowing large cell numbers to be frozen in one vial.
LUBBOCK, TEXAS--Microbiologist TEXAS--Microbiologist TEXAS--Microbiologist Thomas Butlerral charges stemming from his report last January that 30 vials of plague bacteria had gone missing from his laboratory here at Texas Tech University Health Sciences Center.
PAGE C1 Split Verdict in Plague Scare A Texas professor was convicted of 47 counts stemming from his having filed a false report that 30 vials of plague bacteria were missing from his laboratory, but he was acquitted of the most serious charges.
