Lessons learned for analysis of mucosal samples using nanowell-based technologies
• Less is more – Minimal sample handling – Direct processing in microtechnology – 1,000 cells – no problem
• More is better – Fresh preferable (viability) – Rare cells are still rare—sampling from finite numbers – Multiple hypotheses for rare states limiting with few cells
• Better is better – Open the spotlight – integrated measures of molecular profiles – Embrace multidimensional analyses to generate hypotheses – Minimize numbers of samples required from patient
