تقنية وصفنا لتجميد خطوط الخلايا الأشكال يعمل بشكل جيد لتخزين بكفاءة وإحياء خطوط الخلايا الأشكال وأيضا أي خلايا الثدييات في المصالح. تجميد نسبة صغيرة من الخلايا في كل مرور اعتبار مهم عند العمل مع خطوط الخلايا HES ، وشذوذ النمط النووي يمكن أن تنشأ خلايا غير طبيعية ويمكن أن تتخذ بسرعة أكثر من خط. وهكذا ، بعد أن جمدت انشقاقات في كل مرور بالإضافة إلى المصارف الكبيرة في بعض المقاطع غير مرغوب فيه للغاية.
