Pituitary Isograft Transplantation in Mice

[Abstract]  The mouse pituitary isograft is a technique developed to administer persistent hormone stimulation, thereby increasing cellular proliferation in the mammary tissue (Christov et al., 1993). The pituitary isograft procedure was first described in ‘Induction of Mammary Cancer in Mice without the Mammary Tumor Agent by Isografts of Hypophyses’ by O. Mühlbock and L. M. Boot in 1959 (Muhlbock and Boot, 1959). Since then, the procedure has seen wide use. A pituitary gland is harvested posthumously from a donor mouse and implanted under the renal capsule of the recipient mouse through a ... [摘要]  小鼠垂体同种异体移植是开发用于施用持续激素刺激的技术,从而增加乳腺组织中的细胞增殖(Christov等人,1993)。垂体同种异体移植手术首先在O.Mühlbock和L.M. Boot于1959年(Muhlbock和Boot,1959)的“Inction of Mammary Cancer in Mice without the Mammary Tumor Agent by Isoplagen of Hypophyses”中被描述。此后,程序得到广泛的应用。从供体小鼠后期收获垂体腺,并通过位于最后肋骨正下方的小腹切口植入受体小鼠的肾囊下。脑垂体植入后,开始释放激素。这些分泌物增加多种激素的血清水平,包括催乳素,孕酮和17β-雌二醇(Christov等人,1993)。尽管这些激素对癌细胞增殖,生长,分化和寿命的影响没有被很好地表征,并且在一些情况下是有争议的,垂体同种移植物的净效应是根据应变特异性增加鼠乳腺组织的增殖特征(Lydon等人,1999)。

Mouse Mammary Intraductal (MIND) Method for Transplantation of Patient Derived Primary DCIS Cells and Cell Lines

[Abstract]  The MIND method involves intraductal injection of patient derived ductal carcinoma in situ (DCIS) cells and DCIS cell lines (MCF10DCIS.COM and SUM225) inside the mouse mammary ducts [Video 1 and Figure 1 in Behbod et al. (2009)]. This method mimics the normal environment of DCIS and facilitates study of the natural progression of human DCIS, i.e., their initial growth as carcinoma in situ within the ducts, followed by invasion into the stroma through the myoepithelial cell layer and basement membrane (Behbod et al., 2009; Valdez et al., 2011). In ... [摘要]  MIND方法涉及管内注射患者来源的导管原位(DCIS)细胞和DCIS细胞系(MCF10DCIS.COM和SUM225)(在小鼠乳腺导管内)[Video 1和FIG 1 in Behbod et al。 >(2009)]。该方法模拟DCIS的正常环境,并且有助于研究人DCIS的自然进展,即它们在导管内原位癌的初始生长,随后是侵入通过肌上皮细胞层和基底膜的基质(Behbod等人,2009; Valdez等人,2011)。为了证明移植手术是成功的,可以早在导管内注射细胞后两周,随后使用人特异性细胞角蛋白5和/或19的苏木精和曙红(H&E)染色和/或免疫荧光染色,切除移植的乳腺[请参见Behbod等人(2009)中的图2-4]。此外,在管内注射后立即在小鼠乳腺导管内存在台盼蓝是注射成功的最佳指示(视频1从4:33秒开始)。
