Problems solved by technology

Therefore, it is not ideal to use the main pulmonary artery to study the mechanism of pulmonary hypertension.
In addition to using animals as materials (mostly rats), foreign scholars also purchased adult pulmonary artery smooth muscle cell lines for experiments, but the cell lines are expensive and not primary cultured cells, and the biological characteristics of the cells have changed. Experimental results; while a small number of scholars have also cultivated adult distal pulmonary artery smooth muscle cells, but the culture medium they use is smooth muscle cell basal medium (SMBM), which is expensive and difficult for domestic general laboratories to accept

Abstract

The invention discloses a method for culturing adult distal end pulmonary artery smooth muscle cells, which comprises following steps: firstly, separating pulmonary artery smooth muscle cells from an adult distal end pulmonary artery smooth muscle layer which is obtained and culturing primary cells, secondly, obtaining the adult distal end pulmonary artery smooth muscle cells which are subcultured, taking out the primary cells and cleaning with PBS solution after the primary cells in the first step grow to the logarithmic growth phase, adding trypsin solution 0.3-0.5ml 0.1%-0.2%, digesting for 2-3 minutes under the temperature of 35-37 DEG C, gettering the trypsin solution when cells appear retraction and the intercellular space is enlarged, adding complete culture medium 3-5ml to enable the trypsin solution to form cell suspension, inoculating in a new culture bottle, changing medium each three days, then, finishing culturing subculture cells, and obtaining the culturing adult distal end pulmonary artery smooth muscle cells which are subcultured. The method for culturing has stable technique and good repeatability, and the cells which are cultured have uniform forms with good growth and have the forms and characteristics of typical smooth muscle cells.

Description

technical field [0001] The invention relates to a cell culture method, in particular to a culture method for adult distal pulmonary artery smooth muscle cells, and belongs to the field of biotechnology. Background technique [0002] Adult distal pulmonary artery smooth muscle cells are important cell materials for studying the pathogenesis of pulmonary circulation-related diseases, especially pulmonary hypertension and other diseases. The current methods for culturing pulmonary artery smooth muscle cells include enzymatic digestion and tissue block patching. Most of the animal sources are rats, and the differences between different species of rats and humans are relatively large, so the significance of using adult pulmonary artery smooth muscle cells to study the pathogenesis of pulmonary hypertension and related research is significantly greater than using animal cells. However, due to the difficulty in obtaining materials, and human beings are highly evolved organisms, it...
