[Abstract]  Medullary thyroid cancers (MTCs) are derived from calcitonin-producing cells (C cells) of neuroendocrine origin. Rb heterozygous mice develop low-grade C cell adenocarcinoma following biallelic inactivation of the Rb tumor suppressor gene loci. Additional inactivation of another tumor suppressor gene such as Trp53, Arf or Cdkn1a allows Rb-deficient mice to generate more aggressive C cell adenocarcinoma (Takahashi et al., 2006; Shamma et al., 2009; Kitajima et al., 2015). To characterize C cell adenocarcinoma cells derived from Rb-deficient mice of different genetic backgrounds, we attempted to extract C cell adenocarcinoma cells from primary thyroid tumor tissue. Since primary mouse small cell lung cancer (SCLC) cells ... [摘要]  甲状腺髓样癌(MTC)源自神经内分泌起源的降钙素产生细胞(C细胞)。Rb 杂合小鼠在b 肿瘤抑制基因位点的双等位基因失活后发展为低级C细胞腺癌。另一种肿瘤抑制基因(例如Trp53 ,Arf 或 Cdkn1a)的额外失活使Rb缺陷型小鼠产生更具侵袭性的C细胞腺癌(Takahashi, 2006; Shamma等人,2009; Kitajima等人,2015年)。为了表征来自不同遗传背景的Rb缺陷小鼠的C细胞腺癌细胞,我们尝试从原发性甲状腺肿瘤组织中提取C细胞腺癌细胞。由于原代小鼠小细胞肺癌(SCLC)细胞起源于也干细胞C的神经内分泌细胞,因此可以建立为非粘附和粘附细胞(Calbo等人,2011),我们将其方法应用于MTC。在这里我们描述我们的隔离技术的非粘附和粘附细胞培养从原发性甲状腺髓样肿瘤组织。我们发现C细胞的分子标记物如降钙素和Ascl1主要富集在非粘附性群体中(Kitajima等人,2015)。这与以下事实一致:最常分布的人MTC细胞系TT之一是非粘附性的。
