[An experimental study on the differentiation of bone marrow mesenchymal stem cells into vascular endothelial cells].

Objective: To investigate the feasibility of differentiation of bone marrow mesenchymal stem cells (MSCs) into vascular endothelial cells and the mechanism of its involvement in wound healing.

Methods: Porcine MSCs were harvested from porcine marrow, and they were isolated and purified by density gradient centrifugation. After being cultured and amplified in vitro, the MSCs were labelled with BrdU (5-bromodeoxy-uridine).

Purification, characterization, and chemical modification of manganese peroxidase from Bjerkandera adusta UAMH 8258.

Ten strains of Bjerkandera adusta from the University of Alberta Microfungus Collection and Herbarium (UAMH) were compared for manganese peroxidase production. The enzyme from B. adusta UAMH 8258 was chosen for further study.
