Human chorionic-plate-derived mesenchymal stem cells and Wharton's jelly-derived mesenchymal stem cells: a comparative analysis of their potential as placenta-derived stem cells.

Placenta-derived stem cells (PDSCs) have gained interest as an alternative source of stem cells for regenerative medicine because of their potential for self-renewal and differentiation and their immunomodulatory properties. Although many studies have characterized various PDSCs biologically, the properties of the self-renewal and differentiation potential among PDSCs have not yet been directly compared. We consider the characterization of chorionic-plate-derived mesenchymal stem cells (CP-MSCs) and Wharton's jelly-derived mesenchymal stem cells (WJ-MSCs) among various PDSCs and the assessment of their differentiation potential to be important for future studies into the applicability and effectiveness of PDSCs in cell therapy.

Degradation of trichloroethylene by photocatalysis in an internally circulating slurry bubble column reactor.

The effects of initial trichloroethylene (TCE) concentration, recirculating liquid flow rate and gas velocity on photodegradation of TCE have been determined in an internally circulating slurry bubble column reactor (0.15m-ID x 0.85 m-high).
