光纤接入和禽流胚胎实验是具有挑战性的，由于约束的鸡蛋壳。窗口大大限制了微血管注射和显微外科方法8访问人数。因此，只有早期胚胎可以被操纵，并连续观察是不可能的。使用培养皿的早期前 OVO文化的用途有限，因为控制不力，对胚胎的表面张力，防止长期文化9。最近，我们改进了这种技术，使用一个六角形的权衡船保持可接受的表面tenstion 7，但这些文化...

了解驱动器正常和畸形的胚胎发育的遗传和微环境因素之间的关系，为发现新的治疗策略的根本。成像技术的进步已使定量调查的组织和成熟的身体计划，但后一阶段的胚胎形态发生目前还不太清楚。鸡胚胎是一个有吸引力的脊椎动物为这个应用程序的模型系统，因为它的文化和手术操作方便。早期胚胎可以培养一个短的时间在滤纸上环，从而使光纤接入完整的细胞图案和命运的研究1,2。学习先进的，如心脏的形态发生发育过程中，传统上通过一个窗口蛋壳3-5，但这种技术限制了光纤接入，由于窗口大小。我们以前开发的一个简单的方法来文化的整个胚胎前，OVO六角权衡船最多至10天，这使得通过高分辨率成像超声6,7。这些文化，运输困难，限制了可用于现场实验的成像工具的类型。我们在座改善与成本效益，便携式环境室的无壳培养体系。鸡蛋被破解到圆周部分用无菌水填充到塑料杯贴上由聚氨酯膜（保鲜）创建了一个吊床。吊床的周长和深度尺寸均保持表面张力的关键，而下的吊床和水力学有助于抑制由运输引起的震动。还开发了一个小的足迹，循环水浴，使实验过程中连续的温度控制。我们证明至少14天的能力，在这样的文化胚胎的无形态发生缺陷或延迟，并聘请几个显微和成像应用这个系统。
