the authors provide the results of a long-term cultivation ( 106 passages during 2 years ) of smooth muscle cells of rat aorta media , where the cells preserve the signs characteristic for their differentiation : ability to contract , specific ultrastructure ( the presence of the caveole series , microfilaments of 4-6 nm , intermediate filaments of 10 nm , dark bodies in the cytoplasm ) , and ability to synthesize the alpha-form of actin specific for smooth muscle vascular cells .
