Embodiment 1
[0033] 1. Design primers
[0034] According to the sequence information of the Twist-1 gene in the NCBI database (its sequence is shown in SEQ ID NO: 3), the present invention has designed primers with excellent specificity for the expression level of the Twist-1 gene, and the primer sequences are as follows:
[0035] Upstream primer 5'-GTCCGCGTCCCACTAGC-3' (SEQ ID NO: 1);
[0036] Downstream primer 5'-TCCATTTTCTCCTTCTCTGGAA-3' (SEQ ID NO: 2);
[0037] The amplified length is 136bp.
[0038] 2. Total RNA extraction and reverse transcription
[0039] The mesenchymal stem cells were cultured to a confluence of about 80%, and the cells were collected after trypsinization, washed three times with PBS, and treated with TRIzol to extract RNA.
[0040] The reverse transcription kit uses the RevertAid First Strand cDNA Synthesis Kit, the reaction system is shown in Table 1, the concentration of Oligo(dT) primer is 100 μM; the reverse transcription reaction conditions include: Stage...
