What experiments can be conducted to compare the proliferation ability of human induced pluripotent stem cell-derived cardiomyocytes (hiPSCCMs) with a specific gene knocked out using CRISPR-Cas9 technology to that of normal cells?
You can run cell proliferation or viability assays. However, a KO cell clone was derived from a single cell and may deviate from parental cells after multiple passages during the clonal expansion. You will have to look at multiple KO clones.
