使用CellPore™递送管搭配CellPore™转染系统，可将多种物质，包括核酸（例如siRNA、mRNA、自扩增RNA）、核糖核蛋白（例如Cas9 RNP）、蛋白质和其他生物分子）递送至多种细胞类型中。这些递送管集成了特定尺寸的微流通道（压缩通道），利用机械形变实现细胞膜的瞬时无毒破坏（机械穿孔）。这种物理递送方法更为温和，是处理敏感和难转染细胞的理想解决方案，同时还能保持细胞的活率和功能。每个递送管均已预组装，包含用于处理细胞和目的物质混合物的递送插件以及用于简化机械穿孔后处理的收集管。每个CellPore™递送管可处理20至200 μL的样本体积。

CellPore™递送管目前提供两种压缩尺寸，每种尺寸均经过专门设计，可兼容多种细胞类型。

 

CellPore™递送管300兼容以下细胞：

  • 未激活的人pan-T细胞
  • 未激活的人CD4+ T细胞
  • 未激活的人CD8+ T细胞
  • 未激活的人调节性T细胞
  • 未激活的人自然杀伤 (NK) 细胞
  • 未激活的人B细胞
  • 人单核细胞
  • 人外周血单个核细胞（PBMCs）
  • 人CD34+造血干祖细胞（HSPCs）
  • 小鼠T细胞

 

CellPore™递送管500兼容以下细胞：

  • 人诱导多能干细胞（iPSCs）
  • 人胚胎干细胞（ESCs）

 

建议将CellPore™递送管与CellPore™递送液和CellPore™细胞转染系统配合使用，以确保在机械穿孔过程中获得最佳递送效率和细胞活率。

Optimizing CellPore™ Delivery Pressure for Efficient Transfection of hPSCs Using FITC-Dextran

Figure 1. Optimizing CellPore™ Delivery Pressure for Efficient Transfection of hPSCs Using FITC-Dextran

Newly passaged hPSC lines were cultured in complete mTeSRTM Medium for 7 days or until reaching 70% confluency. FITC-dextran was delivered to 3.5 x 105 cells per reaction in increasing pressure (5 - 25 psi). Immediately after delivery, cells were analyzed by flow cytometry to determine cargo delivery efficiency and cell viability. Conditions that maximized delivery efficiency with limited impacts to hPSC viability were determined to be 15 psi across 3 lines tested: (A) SCTi003-A hiPSC, (B) WLS-1C hiPSC, and (C) H9 hESC lines. The ”Endocytosis” condition indicates a control where cells are incubated in the presence of FITC-dextran without mechanoporation. “Untreated” indicates an unmanipulated sample without FITC-dextran. Data are presented as mean ± SD (n = 3).

The CellPore™ Transfection System Enables Reliable Cas9-RNP Editing Across a Wide Range of Cell Numbers

Figure 2. The CellPore™ Transfection System Enables Reliable Cas9-RNP Editing Across a Wide Range of Cell Numbers

RNP complexes targeting the B2M gene (1:2.5 Cas9:sgRNA mol ratio) were delivered to a range of hPSC numbers per reaction (from 3.5 × 105 up to 2 × 106) in 50 µL reactions at 15 psi. Cells were cultured for 2 days post-transfection to allow sufficient time for MHC-I surface marker knockout. Comparable viability, editing efficiency, and expansion were obtained across the cell number range tested for (A) SCTi003-A hiPSCs, (B) WLS-1C hiPSCs, and (C) H9 hESCs. No cargo indicates mechanoporation of hPSCs without RNP complexes at 3.5 × 105 cells per reaction. Data are presented as mean ± SD (n = 3).

Gene-Edited hPSCs Manipulated by CellPore™ and Maintained in mTeSR™ Plus Are of High Cell Quality

Figure 3. Gene-Edited hPSCs Manipulated by CellPore™ and Maintained in mTeSR™ Plus Are of High Cell Quality

(A) Gene-edited hESC (H9) and hiPSC (WLS-1C, SCTi003-A) maintained in mTeSR™ Plus on Corning® Matrigel® Matrix continue to exhibit classic hPSC morphology throughout the culture with densely packed, multilayered colonies. (B) hPSCs manipulated by CellPore™ (orange bars) harvested at Day 14 post-transfection were characterized for markers of the undifferentiated state, with > 90% of cells manipulated by CellPore™ (orange bars) staining positive for TRA-1-60 (left) and OCT4 (right), as determined by flow cytometry. Graphs show average expression (± standard deviation) results from analyses of 3 independent experiments. Genetic characterization using single nucleotide polymorphism array (SNPa) profiling confirmed no genetic perturbation across all 3 lines (data not shown).
