MED64應用手冊：人類干細胞來源的心肌細胞應用

關鍵詞：
人類干細胞來源的心肌細胞 Human stem cell-derived cardiomyocytes (hSC-CMs) 搏動頻率 beat frequency; 場電位時程 field potential duration (FPD)
慢性藥物作用 chronotropic drug effects; 藥物篩選 drug screening

人類干細胞來源的心肌細胞是制藥公司和科研機構在研究中應用得比較多的樣本。由于人類干細胞來源的心肌細胞具有和原代人類心肌細胞一樣的遺傳背景，它們的藥理學特性應該非常相似，因此結合人類干細胞來源的心肌細胞與MED64多電極胞外記錄系統的平臺已成為了研究人類遺傳性心肌疾病模型和藥物篩選的主流。
只需要將hSC-CMs培養(yǎng)在MED記錄電極上，就可以從MED64系統中記錄和提取出基本的電生理參數，比如搏動頻率、以場電位時程等。另外，由于電極的非侵入特性，穩(wěn)定的記錄可以持續(xù)非常長的時間，因此慢性藥物的效果也能夠在MED64系統上進行測量。不僅如此，MED64還可以使用任意電極輸出刺激來Pace hSC-CMs，因此可用來研究頻率依賴或使用依賴的藥物作用。
