Nuclear Shape in Muscle Cells
Every student of muscle ultrastructure is familiar with the frequently convoluted appearance of the muscle cell nucleus (e .g . Figs . 1-3) . It is a reasonable assumption that this particular shape of the nucleus can be correlated with the contracted state of the muscle fiber . Lane (12) was able to show that in contracting intestinal smooth muscle cells the nucleus undergoes a change from an ...
متن کاملSmooth muscle phenotypic modulation--a personal experience.
The idea that smooth muscle cells can exist in multiple phenotypic states depending on the functional demands placed upon them has been around for >5 decades. However, much of the literature today refers to only recent articles, giving the impression that it is a new idea. At the same time, the current trend is to delve deeper and deeper into transcriptional regulation of smooth muscle genes, a...
متن کاملUse of Nuclear Spin Noise Spectroscopy to Monitor Slow Magnetization Buildup at Millikelvin Temperatures
At ultralow temperatures, longitudinal nuclear magnetic relaxation times become exceedingly long and spectral lines are very broad. These facts pose particular challenges for the measurement of NMR spectra and spin relaxation phenomena. Nuclear spin noise spectroscopy is used to monitor proton spin polarization buildup to thermal equilibrium of a mixture of glycerol, water, and copper oxide nan...
متن کاملExpression of nuclear lamin A and muscle-specific proteins in differentiating muscle cells in ovo and in vitro
Primary cultures and tissue samples of chicken embryonic muscle were immunologically probed for the expression of muscle-specific proteins, such as myosin heavy chain and the tropomyosins, as well as for the nuclear lamina protein, lamin A. As determined by quantitative immunoblotting, the expression of lamin A and the muscle-specific proteins were at low levels or absent in predifferentiation ...
