Ready-to-use 3D Human Pulmonary Alveolar Epithelial Cell Spheroids：
The lung is a complex organ with a large and highly vascularized epithelial surface area. Gas exchange in the lung occurs in the air-filled alveoli containing type I and II alveolar epithelial cells. Type II cells function as progenitor cells in the alveoli and proliferate and differentiate into type I cells, while type I cells are involved in gas exchange [1]. Type II cells not only proliferate to maintain the epithelium but also play critical roles in respiration and host defense mechanism through production of the pulmonary surfactants (SPs) [1]. Type II cells, however, lose their functional markers within a few days of cultivation in 2D culture. Studies have shown that when alveolar epithelial cells are cultured in three-dimensional (3D) cell culture, cells maintain their epithelial functional markers [2]. To provide a more native in vitro lung model, ScienCell offers ready-to-use human pulmonary alveolar epithelial cell spheroids (SP3D-HPAEpiS), which express the surfactant proteins such as SP-A, -B, -C, and –D (Figures 1 and 2). These spheroids are ready for experiments at 24 hours post thawing, and are an excellent in vitro model for studying the contribution of the alveolar epithelial cells to alveolar maintenance and repair.肺是一个复杂的器官，具有大而高度血管化的上皮表面积。肺内气体交换发生在含有I型和II型肺泡上皮细胞的充气肺泡内。II型细胞在肺泡中起祖细胞的作用，增殖分化为I型细胞，I型细胞参与气体交换[1]。II型细胞不仅通过增殖维持上皮细胞，还通过产生肺表面活性剂(SPs)[1]在呼吸和宿主防御机制中发挥重要作用。然而，在2D培养的几天内，II型细胞失去了它们的功能标记。研究表明，肺泡上皮细胞在三维(3D)细胞培养中，细胞维持其上皮功能标志物[2]。提供更多本机体外肺模型,ScienCell提供现成的人类肺肺泡上皮细胞球状体(SP3D-HPAEpiS),蛋白质表达的表面活性剂如SP-A - b, c,和- d(图1和图2)。这些球状体准备好实验在解冻后24小时,和一个优秀的体外模型研究的贡献肺泡上皮细胞,肺泡进行维护和维修。
