FLEXcyte 96 - 生理学的条件での収縮力測定を実現

FLEXcyte 96 は,新次元の心筋細胞のin vitro収縮力測定を実現します。心筋細胞に対して成分が明確かつフレキシブルな器材を使用することは成熟化および成熟化細胞の応答を促し,ハイスループットでの幹細胞由来心筋細胞の薬理評価系を可能にします。細胞は弾力性培養器材上に単層で接着し,同期拍動する単層細胞の収縮力が96ウェルプレートで測定されます。この独自技術により,心臓の機械的条件に近い生体を模した環境を実現しています。FLEXcyte 96は心毒性および安全性,高効率スクリーニングや基礎研究における構造的,機能的な収縮力測定のターンキーシステムです。


FLEXcyte 96 は CardioExcyte 96 の追加オプションです。FLEXcyte 96 ディスポ式プレートは厚み10 μm以下かつ高度な表面処理を行ったPDMS膜(ポリジメチルシロキサン膜)であり,nativeなヒト心筋組織の生理学的な伸縮性と強力な機械的支持を実現します。心筋の律動性収縮は96ウェルのPDMS膜を培地の重みで偏向しながら上方へと持ち上げます。この偏向の変化を測定することで機械的応力が計算されます。


システムは多様な市販の幹細胞由来心筋細胞(Ncardia,FUJIFLM CDI,Axol,NEXEL社など)でバリデートされています。ヒトiPS細胞由来心筋細胞(hiPSC- CMs)は陽性変力反応を示し,「成熟化」の為に追加でペーシング等のよる刺激が必要ありません。

僅かな細胞の応答も見逃しません。心筋細胞の収縮力測定により慢性および急性の両アプリケーションにおける安全性,有効性,毒性評価を確実に実施できます。FLEXcyte 96 は完全自動の測定装置であり,96ウェル同時測定が可能です。 

FLEXcyte 96 の主な特徴と優位性:

  • 真の収縮力測定
  • 成熟化細胞の応答取得を促進
  • 生理学的機械条件
  • ハイスループット,96ウェル同時測定
  • 急性および慢性評価
  • 光学ペーシングオプション

CardioExcyte 96/ FLEXcyte 96 パッケージには専用のインキュベーションシステムが含まれており,通常の培養インキュベータは不要です。システムを実験台に設置したままで温湿度およびCO2がコントロール可能です。
 CardioExcyte 96/ FLEXcyte 96 システムにはデータ解析とエクスポート用の強力なソフトウェアパッケージが同梱されており,効率性と簡便性を支える大きな特徴のひとつとなっています。

オプション&特徴

CardioExcyte 96/ FLEXcyte 96 Platform

CardioExcyte Integra 1

The CardioExcyte 96/ FLEXcyte 96 package contains an Integra Viaflo Assist that provides automated multichannel pipetting for reproducible 96 well plate handling of cells and compounds.


FLEXcyte 96 Incubation System

FLEXcyte incubation system

The FLEXcyte 96 package includes an Incubation System. This means that the measurements are performed outside the cell culture incubator and the complete setup fits on a lab benchtop. The FLEXcyte 96 Incubation System controls temperature, gas mix and humidity.


FLEXcyte 96 SOL (Add-On)

Optical stimulation and investigation of contraction force in parallel:

CardioExcyte Sol 1

The stimulating optical lid, CardioExcyte 96/ FLEXcyte SOL, uses LEDs for spatially uniform stimulation of cells transfected with light-gated ion channels such as Channelrhodopsin2 (ChR2). After transfection of iPS cardiomyocytes with ChR2 the cells can be stimulated by blue light. Each light impulse induces a depolarization of the cells and thus an action potential is triggered. The advantages of optical stimulation over electrical stimulation include the highly precise timing, all cells of the beating network are stimulated exactly at the time of the light stimulus. In contrast, electrical stimulation propagates from the electrode across the well and thus cells are stimulated progressively. A mean beat calculation of precisely timed beats enables in-depth compound analysis and concentration response dependencies to be obtained. This is one of the key software capabilities of the CardioExcyte Control/ DataControl software package that is provided with each CardioExcyte 96/ FLEXcyte 96 system.


ソフトウェア

 

CardioExcyte 96/ FLEXcyte 96 Software package

FLEXcyte 96 Analysis

An adaptive signal detection algorithm extracts the positions and values of beating events. Besides beat intervals, amplitudes, rising and falling time, Pulse witdhs are detected (upper figure). Furthermore, integrals (blue and red) and arrhythmia (yellow) are identified and quantified as well.

The CardioExcyte/ FLEXcyte Control software supports online analysis of contractility parameters. The unique Mean Beat Function automatically visualizes the average of beat traces from one well, enveloped by the standard deviation, indicating the consistency of the beat pattern within the recorded well, i.e. if the cellular network is synchronously beating or not. The control software is intuitive and easy-to-use, at the same time very powerful in terms of experimental setup and online visualization of the recorded data.

The DataControl 96 software package is an independent software package to load and analyze data recorded on the CardioExcyte 96 or FLEXcyte 96. The analysis template can be saved and reloaded. Customized export formats of analysis results are integrated.

FLX-96

FLEXcyte plate principle

The FLX-96 FLEXcyte membrane plates come in a standard 96-well format, allowing for automated liquid handling and easy integration into your lab procedures. After 7 days of culture, the cells have formed a biohybrid material with the membranes and are ready for assay. For further maturation in the physiological environment provided by the FLEXcyte 96 plates, the cells can be cultured for up to 4 weeks. The FLX-96 plates are a proprietary innovative product by innoVitro, developed for the FLEXcyte 96. It is produced and quality-assured in-house at innoVitro headquarters and shipped to our international customers.
With less than 10 μm in thickness and sophisticated surface modification, the polydimethylsiloxane (PDMS) membranes of the FLEXcyte 96 plates combine both physiological elasticity of native human heart tissue and strong mechanical support.


Description and Material

• Standard 96-well plate format
• Working volume: 200 µl (surface 34 mm2)
• Substrate: <10 µM thick PDMS (polydimethylsiloxane) flexible membrane
• Supports mature cell behavior

Common systems for the quantification of cellular contraction rely on animal-based models, complex experimental setups or indirect approaches. Integration into standard lab procedures remains a challenge for current in vitro systems. The FLEXcyte 96 system has the potential to scale-up mechanical testing towards medium-throughput analyses. We show here that, using stem cell-derived cardiomyocytes, this system enables predictive recordings of contractile behaviour in the presence of well-known reference compounds.
