Tracheary element differentiation and secondary cell-wall formation have been studied in cell cultures of coniferous gymnosperms. Factors that influence tracheary element differentiation are (i) the sucrose concentration in the media, (ii) the concentration of nutrients in the media, (iii) temperature and light, and (iv) the types and concentrations of phytohormones in the media. There are adva...

Plantlets grown in conventional tissue culture systems usually encounter physiological and anatomical abnormalities including inability to photosynthesize, low chlorophyll content, open stomata, lack of a cuticle layer in the leaf, abnormal xylem parenchyma etc. Photoautotrophic and photomixotrophic systems could diminish these problems. The purpose of this study was to increase the chlorophyll...

In this study, neural cell sorting of high throughput and high purity is made using two-step separation by combining soft inertial microfluidics and pinched flow fractionation. Both finite element analysis tool and equivalent electric circuits modeling were used to design the microfluidic devices. Separation between neurons and glia cells from rat’s spine cord was demonstrated. To minimize the ...

Saccharomyces cerevisiae (baker’s yeast) can exhibit sustained oscillations during the operation in a continuous bioreactor that adversely affects its stability and productivity. Because of heterogeneous nature of cell populations, the cell population balance equation (PBE) can be used to capture the dynamic behavior of such cultures. In this work, an unstructured-segregated model is used f...
