smooth muscle cell- cells of the smooth muscles muscle cell,muscle fiber,muscle fibre- an elongated contractile cell that forms the muscles of the body smooth muscle- muscle tissue that does not appear striated under the microscope; has the form of thin layers or sheets ...
Smooth Muscle Smooth muscle lacks the striations of skeletal and cardiac muscle because the actin and myosin filaments are not regularly arrayed along the length of the cell. Instead, the arrangement of filaments is less regimented and occurs as a spiral. Smooth muscle cells are spindle-shaped, ...
The major feature of any mature smooth muscle cell under the transmission electron microscope is the dense appearance of numerous parallel myofilaments in the cytoplasm running along the longitudinal axis (Figure 1). These comprise mainly smooth muscle myosin heavy-chain thick and smooth muscle α-...
We next investigated the impact of AMPK-α1/α2 deletion on voltage-gated potassium (KV) currents in acutely isolated pulmonary arterial smooth muscle cells, because reduced activity and/or expression of KV1.5 has been identified as a hallmark of persistent pulmonary hypertension in neonates52,53an...
For cultured SMCs, abundant expression of alpha-smooth muscle cell actin was observed universally under fluorescence microscope. Confocal laser scanning microscope testified that cultured cells were double positive of alpha-smooth muscle actin and calponin.Conclusions: This is the first report of ...

it appears homogenous. Smooth muscle cytoplasm contains large amounts of actin and myosin. Actin and myosin act as the main proteins involved in muscle contraction. Actin filaments attach to dense bodies spread throughout the cell. Dense bodies can be observed under an electron microscope and appea...
microscope and SABC kit.Results:The cultured cells possessed "peak and valley" characteristics for VSMCs under microscope.Immunohistochemical staining with antibody against SM-α-actin demonstrated these cells were positive.The cell viability was 95% in subculture by trypan blue.Conclusion:The highly ...
Smooth muscle contains interdigitating thick and thin filaments, but their order is not nearly as precise as exists in striated muscle, giving rise to a ‘smooth’ versus striated appearance in the light microscope. The difference in microscopic appearance between smooth muscle and skeletal muscle ...
1A). Nano-sized HAp was observed on the surface of the vascular cells by scanning electron microscope (SEM) (Fig. 1B). Energy dispersive spectrometer (EDS) of the dense structures under SEM revealed calcium and phosphorus, with small amounts of magnesium and carbon (Fig S2). The ratio of...
