Title: Method for producing human intervertebral disc cells
Inventor: HANLEY EDWARD NATHANIEL JR
IPC: A61K35/12
Filed: 1998-11-24
Abstract: There is provided a method for growing human intervertebral cells. Disc tissue is surgically removed from a normal disc of a patient, the cells expanded by feeding with a cell stimulant such as a growth factor, or a cytokine or a bioactive agent to form monolayer primary cell cultures on a plastic mesh such as a nylon mesh. In the case of a growth factor, fetal bovine serum is preferred as it improves cell proliferation and production of appropriate extracellular matrix components. In another aspect of this invention, the monolayer primary cell cultures are seeded in alginate or agarose and fed again with the cell stimulant until three-dimensional cell cultures are formed. The cells are recovered from the alginate or agarose or from monolayer cultures. Re-implantation is carried out using bioresorbable carriers or cell suspensions.
Patent CA-2313579-A1 (CA)
Inventor: SMITH LARRY NEIL
IPC: A01D57/20
Filed: 2000-07-07
Abstract: A self-propelled mowing vehicle includes a chassis supported on front and rear pairs of transversely spaced wheels. At least a front-mounted mowing unit is attached to a front end of the chassis and operates to deliver cut crop to a longitudinally extending first section of a flat belt conveyor assembly which includes at least a second section that receives crop from the first section and delivers it transversely. In accordance with a first embodiment, the first conveyor section terminates at the rear sides of the front pair of wheels and the second conveyor section extends perpendicular to a longitudinal centerline of the vehicle and is mounted for sliding movement so as to selectively deliver crop to either side of the vehicle. In accordance with another embodiment the first conveyor section extends to the rear end of the vehicle and the second conveyor section is mounted for pivoting about an upright axis so as to selectively deliver crop to opposite sides of the vehicle or to strew the crop across its full range of movement. In accordance with still another embodiment, the conveyor arrangement includes second and third fixed conveyor sections located transversely to and on opposite sides of the vehicle centerline, with the first conveyor section being divided so as to divide the transported crop into two streams which are respectively deposited onto the second and third conveyor sections. Opposite side mowing units may be used with the front-mounted unit and when so used the second conveyor section operates to lay crop closely beside windrows formed by the first conveyor section so that the double windrows may be gathered by a wide pickup of a machine for further processing the crop.

Title: Human brain endothelial cells and growth medium and method for expansion of primitive cd34+cd38- bone marrow stem cells
Inventor: SAINI ABHA A
IPC: C12R1/91
Filed: 1999-12-03
Abstract: A novel co-culture system using human brain endothelial cells (HUBEC) which promotes the expansion of human CD34+CD38- cells consistent with the PMVEC  system is disclosed. HUBEC were isolated from cadaveric donors, passed in primary culture, cloned and found to be Von Willebrand Factor positive.  Cultivation of purified bone marrow CD34+ cells on HUBEC monolayers supplemented with GM-CSF+IL-3+IL-6+SCF+flt-3 ligand caused a 14.5-fold increase in total cells, an 6.6-fold increase in CD34+ cells, and, most remarkably, a 440-fold increase in CD34+CD38- cells after 7 days. Further, CFU-GM production increased 15.1-fold, BFU-E increased 8-fold and CFU-Mix increased 5.2-fold. Optimal generation was dependent upon the continued presence of exogenous supplied cytokines. In comparison, identically treated stroma-free suspension cultures supported a 10.2-fold expansion of total cells, a 3-fold increase in CD34+ cells and maintained the CD34+CD38- cell pool after 7 days of culture. Moreover, we found that non-brain human endothelial cells isolated from the same donors supported neither the expansion nor the maintenance of human CD34+CD38- cells. Although few steady state CD34+CD38- cells give rise to visible colony-forming cells in methylcellulose cultures, our FACS based cell cycle and sorting experiments demonstrated the activation of a highly clonogenic CD34+CD38- population (24 %  cloning efficiency) during ex-vivo culture on cytokine treated HUBEC. These results suggest that bone marrow CD34+CD38- cells require a stromal cell microenvironment for optimal expansion and that ex-vivo expanded CD34+CD38-cells generated in the HUBEC culture system appear to retain some degree of primitive "stemness".
