Organ-on-a-Chip片上器官組織內皮屏障

說明

這種芯片的設計可以模擬1）三維組織和內皮屏障的形成，2）它們的交互作用。該裝置包括狹縫或間隙，以形成外部通道和內部腔室之間的交叉點。通過這種方式，有可能重建對可靠組織模型（如血腦屏障和其他內皮/組織界面）至關重要的緊密和間隙連接。

重建三維組織模型的可能性通過提供更準確地描述體內真實情況的生物和形態學微環境以及確保方便的實時可視化，加速了細胞行為和藥物篩選的實時研究。

通道尺寸、組織腔尺寸、支架和屏障設計有多種選擇（見規范）。我們可以支持您的選擇，并根據您的需要選擇正確的參數。

這種智能和創新的設計克服了當前流動室或基于跨井室的分析固有的局限性。目前的流動腔設計過于簡單化，描繪了微環境的尺度和幾何結構，無法對輪回進行建模。同樣，在活體內觀察到的流體剪切和尺寸/拓撲結構也不在井腔中，遷移的終點測量不可重復，也不能提供實時可視化。

這種簡化和理想化的微血管網絡很容易再現細胞分層、恒定剪切和流動條件。

好處：

并行架構實現了定量實時可視化

具有工程多孔結構的生理性滲漏血管

物理上真實的對流和擴散輸運

超低消耗量微氟平臺

高抗光透明材料

默認顯微鏡玻片尺寸

Organ-on-a-Chip片上器官組織內皮屏障

Description

The design of this chip allows to mimic 1) the formation of 3D tissues and endothelial barrier and 2) their cross-talk interactions. The device includes slits or gaps to form the intersection between the outer channel and inner chamber. In this way it is possible to recreate tight and gap junctions essential for a reliable tissue modelling (such as the blood-brain barrier and other endothelial/tissue interfaces). 

The possibility to recreate 3D tissue models accelerates real-time studies of cellular behavior and drug screening by providing a biological and morphological microenvironment that more accurately depicts in vivo reality and ensuring a convenient real-time visualization.

Several options for channel size, tissue chamber size, scaffolding and barrier design are available (see the Specifications). We can support you in your choice and select the right parameters by following your needs. 

This smart and innovative design overcomes the current limitations inherent in flow chambers or Transwell chamber based assays. Current flow chamber designs are oversimplified, lack the scale and geometry of the microenvironment and cannot model transmigration. Similarly, Transwell chambers do not account for fluid shear and size/topology observed in vivo, the end point measurements of migration are not reproducible and do not provide real-time visualization.

This simplified and idealized microvascular network easily reproduce the cellular stratification, constant shear and flow conditions.

Benefits:

• Side by side architecture enables quantitative real time visualization
• Physiological leaky vasculature with engineered porous structures
• Physiologically realistic convective and diffusive transport
• Microfluidic platform with ultra-low consumable volumes
• Highly-resistant and optically clear material
• Standard microscope glass slide size
