Cell-to-cell communication is vital to the growth and development of multicellularly structured organisms. Recent studies have demonstrated that plants have an endogenous machinery to transport macromolecules such as proteins and nucleic acids between cells through plasmodesmata. Such transport may be a novel means of cell-to-cell signalling. Here, Biao(More)
The aim of the present study was to investigate the potential effects of photodynamic therapy (PDT) mediated by the cationic porphyrin, 5,10,15,20-tetra-(N-methyl-4-pyridyl)porphine (TMPyP 4), on an ovarian carcinoma cell line and the underlying mechanisms by which TMPyP 4-PDT exerts its actions. The analysis of cell viability, hematoxylin and eosin(More)
