| 目的：筛选适合充当组织工程皮肤的种子细胞，比较原代培养的人原代上皮角质形成细胞和永生化的上皮角质形成细胞
HaCaT 的增值能力。方法：将两种细胞（小儿包皮环切术后的组织培养表皮角质形成细胞，永生化的上皮角质形成细胞HaCaT），
分别接种于96 孔板，通过MTT 检测细胞1，3，5，7，9，11 天的生长情况；当两种细胞融合至60%时分别取1×106 个细胞，通过流
式细胞检测细胞的周期。结果：永生化的上皮角质形成细胞HaCaT 每隔一天即可传代一次，原代上皮角质形成细胞每3 天传代一
次；细胞周期：永生化上皮角质形成细胞HaCaT 的G1 期和S 期的比例高于原代上皮角质形成细胞。生长曲线：MTT 检测两种细
胞1,3,5,7,9,11 的生长情况，永生化的上皮角质形成细胞HaCaT 的生长速度明显高于原代上皮角质形成细胞。结论：永生化上皮
角质形成细胞HaCaT 的增殖能力要高于原代培养的上皮角质形成细胞。 |

| Objective: To compare proliferation capacity of human primary keratinocytes and immortalized epiderm cell line
HaCaT. Methods: Getting normal skin biopsy samples (sampleswere obtained from foreskin circumcision) to culture keratinocytes,
immortalized epidrem cell line Hacat, two kinds of cells were seeded in 96 well plates, cells growth curve were detected by MTT, when
two kinds cells mixed 60% taking 1 × 106 cells by flow cytometry to detect cell cycle. Results: Immortalized epiderm cell line Hacat can
be passaged once every other day, human primary keratinocytes can be passaged every three days. Cell cycle: immortalized epiderm
HaCat G1 phase and S phase was higher than primary keratinocytes. Growth curve: MTT detected two kinds cells 1,3,5,7,9,11 growth
situation, immortalized epiderm cell line HaCat grow faster than primary keratinocytes. Conclusion: Immortalized epiderm HaCat
proliferation ability better than primary keratinocytes. |
