Abstract

多年来,大多数涉及角质形成细胞的研究都是使用人类和小鼠皮肤表皮角质形成细胞进行的。近年来,口腔角质形成细胞因其独特的功能和特点而受到关注。它们维持口腔上皮的稳态,并作为再生疗法应用的资源。然而,由于缺乏有效且完善的培养方案,使用成年小鼠口服原发性角质形成细胞的 体外 研究受到限制。在这里,从成年小鼠的上颚组织中分离出口服原代角质形成细胞,并在补充有螯合血清的商用低钙培养基中培养。在这些条件下,角质形成细胞保持在增殖或干细胞样状态,即使在增加传代后,它们的分化也被抑制。标记表达分析表明,培养的口腔角质形成细胞表达基底细胞标志物p63、K14和α6-整合素,分化标志物K13和成纤维细胞标志物PDGFRα阴性。该方法产生的活细胞和可培养细胞适合于在 体外研究口腔上皮干细胞功能的下游应用。
