Core Tip

Core Tip: How to harvest sufficient neural stem cells (NSCs) is a basic requirement for the study and clinical application of NSCs. This study describes a simplified and efficient method for neonatal rat brain-derived NSC culture and identification comprehensively considering the influencing factors including timing of passaging, passage number, passaging approaches and methods for cell identification. It demonstrates that combination of TrypLTM Express and mechanical tapping and pipetting techniques makes a more efficient way of passaging. The optimal timing for NSC passage is on the fourth to fifth day of primary or passage NSC culture.
