Summary
Functional biological assays, including the chicken embryo chorioallantoic membrane (CAM) assay and angiogenesis assays, confirm that electric field-driven cell processing maintains cell viability and function for 3D tissue reconstruction.
Area of Science:
- Biotechnology and Biomedical Engineering
- Cell Biology and Tissue Engineering
- Regenerative Medicine
Background:
- Advanced biological assays are essential for evaluating biological processes and materials.
- The chicken embryo chorioallantoic membrane (CAM) assay and angiogenesis assays are established in vivo and in vitro methods, respectively.
- These assays are crucial for assessing cell behavior and function in various applications.
Purpose of the Study:
- To assess the viability and functionality of human umbilical vein endothelial cells processed using electric field and non-electric field spraying/spinning techniques.
- To compare the angiogenic potential and microvasculature formation of processed cells against controls.
- To evaluate the utility of these cell processing techniques for constructing 3D biological architectures.
Main Methods:
- Human umbilical vein endothelial cells were processed using electric field and non-electric field driven spraying and spinning methods.
- Cell viability was assessed using flow cytometry.
- Angiogenesis was evaluated using angiogenic assays and CD31 immunostaining.
- Microvasculature formation was assessed using the chicken embryo chorioallantoic membrane (CAM) assay.
Main Results:
- Post-processed cells demonstrated comparable viability to controls, as confirmed by flow cytometry.
- Angiogenic sprouting and microtubule formation were similar in post-treated cells and controls, assessed via CD31 immunostaining and angiogenic assays.
- The CAM assay revealed that post-processed cells formed microvasculature indistinguishable from controls.
Conclusions:
- Electric field-driven cell processing techniques maintain cell viability and angiogenic potential.
- These methods are suitable for reconstructing 3D biological architectures for applications in tissue engineering and drug discovery.
- The study supports the advancement of these platform biotechniques for biomedical laboratory and clinical use.
