Ageing and the Influx of Water into Radish Root-hair Cells
A micropotometric device previously described by the writer was used to determine quantitatively the velocity of water influx in cubic microns per square micron of hair surface per minute of comparatively older and younger root hairs of radish seedlings in a humid atmosphere at 29 degrees +/- 1 degrees C. when the micropotometers were filled with Hoagland solution at pH 6.8. In each experiment,...
متن کاملEffect of Neurotrophin-3 on Differentiation of Rat Hair Follicle Stem Cells into Neural Like Cells
Purpose: The aim of this study was to evaluate the effect of NT-3 on the decrease of the differentiation time of bulge stem cells of rat hair follicle from neuron like cells.Materials and Methods: The bulge region of the rat whisker was isolated from and cultured in DMEM/F12 supplemented with epidermal growth factor (EGF) in 3 groups for 7, 8 and 9 days .Then 10 ng/ml NT-3 was added to each gro...
متن کاملPolyribosomes and Cisternal Accumulations in Root Cells of Radish
The zone of root hair formation of seedling radish roots, Raphanus sativus L., was studied by phase-contrast and electron microscopy. Localized dilations of the endoplasmic reticulum, which contained a moderately dense proteinaceous material, were found to be a common component of the cytoplasm in cells of the epidermis and cortex. The surfaces of these dilations were covered with polyribosomes...
