Abstract: The present invention provides a method for preparing dissolved salivary gland tissue, capable of generating stem cells from salivary glands. The method comprises the steps of: adding collagenase to human salivary gland tissue, followed by shake culture, to dissolve the tissue; homogenizing the dissolved tissue; and adding collagenase and hyaluronidase-1 to the homogenized tissue, followed by shake culture, to hydrolyze glycoside bonds in the tissue. Further, the present invention provides a method for preparing adult stem cells derived from human salivary gland tissue, comprising the step of: adding the dissolved salivary gland tissue, which is prepared by the foregoing method, to a medium containing dexamethasone, mercaptoethanol, oncostatin M, and leukemia inhibitory factor (LIF), followed by culture, and then collecting stem cells from the culture liquid. Further, the present invention relates to adult stem cells derived from human salivary gland tissue, wherein the adult stem cells are prepared by the foregoing method and expresses stem cell type cell surface markers CD44, CD49f, CD90, CD105, Oct-4, and Nestin. Further, the present invention relates to a cell therapeutic agent for treating the damage of salivary glands, comprising, as an active ingredient, the adult stem cells derived from human salivary gland tissue.
Abstract translation: 本发明提供一种能够从唾液腺产生干细胞的溶解唾液腺组织的制备方法。 该方法包括以下步骤：向人体唾液腺组织中加入胶原酶，摇动培养，溶解组织; 均质化溶解组织; 并将胶原酶和透明质酸酶-1加入均质组织中，然后摇动培养，水解组织中的糖苷键。 此外，本发明提供了一种制备源自人唾液腺组织的成体干细胞的方法，包括以下步骤：将通过上述方法制备的溶解唾液腺组织加入含有地塞米松，巯基乙醇，制瘤素M ，和白血病抑制因子（LIF），然后培养，然后从培养液中收集干细胞。 此外，本发明涉及源自人唾液腺组织的成体干细胞，其中通过上述方法制备成体干细胞，并表达干细胞型细胞表面标志物CD44，CD49f，CD90，CD105，Oct-4和巢蛋白 。 此外，本发明涉及用于治疗唾液腺损伤的细胞治疗剂，其包含源自人唾液腺组织的成体干细胞作为活性成分。
