肢端黑色素瘤是中国黑色素瘤的主要亚型。然而,目前大多数研究集中在非肢端黑色素瘤。大多数永生化黑色素瘤细胞系和原代细胞不是来自肢端黑色素瘤。此外,关于肢端黑色素瘤细胞原代培养方法及相关动物模型的建立也鲜见报道。在这里,我们提出了四个新的人类原发性肢端黑色素瘤细胞系。为了确定已建立的原代黑色素瘤细胞的突变谱以供将来靶向使用,我们进行了外显子组测序。接下来,我们通过集落形成测定和CCK 8测定来检查原发性肢端黑素瘤细胞的细胞增殖。我们还评估了XYAM-4在体内的增殖和转移潜力。我们报告了一个详细的方案,建立培养的原代肢端黑色素瘤细胞为中国患者和相关的动物模型。我们还总结了我们的肢端黑色素瘤细胞系和现有肢端黑色素瘤细胞系的特点。这将为中国患者的药物反应和个体化治疗研究以及西方和中国人群黑色素瘤的比较研究提供有效的研究工具。
Acral melanoma is the major subtype of melanoma in Chinese patients. However, a majority of current studies focused on non‐acral melanoma. Most immortalized melanoma cell lines and primary cells were not from acral melanoma. Besides, there are rarely reports about methods for establishing primary acral melanoma cell cultures and related animal models. Here, we present four new human primary acral melanoma cell lines. To determine the mutational profile of the established primary melanoma cells for future targeted use, we performed exome sequencing. We next examined cell proliferation of the primary acral melanoma cells by colony‐formation assays and CCK8 assay. We also evaluated the proliferative and metastatic potential of XYAM‐4 in vivo. We report a detailed protocol for establishing cultured primary acral melanoma cells for Chinese patients and related animal models. We also summarize the features in our acral melanoma cell lines and the existing acral melanoma cell lines. This will provide an effective research tool for research on drug responses and individualized treatment for Chinese patients and comparative studies of melanomas between western and Chinese populations.
