ملخص المقالة :
در مقاله حاضر به بررسي کاربرد پليمرهاي مختلف در زمينه پزشکي بازساختي (regenerative medicine) پرداخته مي شود. پزشکي بازساختي به عنوان شاخه‌اي از علم نوين پزشکي با هدف ترميم و احياي بافت، ارگان يا اندام آسيب‌ديده و حتي در مواردي از دست رفته مي‌باشد. استفاده از سلول‌هاي بنيادي (stem cells) براي درمان بيماري‌هاي مختلف يکي از موضوعات جالب توجه در پزشکي بازساختي مي‌باشد. با توجه به حساسيت بالاي چگونگي استفاده و نيز حمل و نقل اين سلول‌ها روش‌هاي مختلفي براي اين منظور پيشنهاد شده است که شامل روش‌هاي قديمي‌تر مانند سلول درماني (cell therapy) و روش‌هاي نوين مبتني بر استفاده از داربست‌ها و سطوح هوشمند مي‌باشد. براي ساخت داربست‌ها بازه‌ي وسيعي از پليمرهاي طبيعي و سنتزي مورد استفاده قرار گرفته‌اند. براي ساخت سطوح هوشمند، روش‌هاي اصلاح سطح مورد‌توجه قرار گرفته‌اند که براي اين منظور از پليمرهاي پاسخگو به محرک‌هاي مختلف به شکل برس‌هاي پليمري بر سطح استفاده مي‌شود.
