PCL poor cell attachment
Fenómeno del problema
PCL tissue engineering scaffolds have poor cell attachment and insufficient bioactivity.
Análisis de la causa
PCL surface is highly hydrophobic; lack of cell recognition sites; low surface energy; poor protein adsorption; biocompatibility is good but activity is insufficient.；During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solución
①Surface coating (collagen, etc.) modification; ②Surface roughening; ③Plasma treatment; ④Blending with bioactive materials; ⑤Cell test verification.；After adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Conclusión clave
PCL cell attachment is the key to tissue engineering; surface modification is the standard method; tests verify bioactivity.；After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
