چکیده

انتخاب نمونه مناسب زیستی برای مطالعات فضایی از اهمیت بسزایی برخوردار است. کشت سوسپانسیون سلول های گیاهی بدلیل دارا بودن جمعیت یکنواخت از سلول‌های در حال تکثیر، شرایط مناسبی را برای مطالعه انواع تنش‌ها از جمله میکروگراویتی فراهم می نمایند. سیستم‌های کشت سلولی در آزمایشگاه می‌تواند به صورت مدل های کشت دو بعدی و سه بعدی انجام شود. در مدل دو بعدی سلول‌ها بصورت تک لایه کشت شده و پاسخ های رشد و تمایز متفاوتی را با شرایط طبیعی نشان می‌دهند. درحالیکه، سلول‌ها در کشت سه بعدی در شرایطی کشت می شوند که مشابه با شرایط طبیعی سلول و بافت در بدن موجود زنده بوده و برای اهداف دارویی، تولید متابولیت های ثانویه و بیومس در مقیاس بالا کاربرد دارد. در این پژوهش، پیشرفت های اخیر و تکنولوژی‌های مورد استفاده برای کشت سه بعدی سلول مورد مطالعه قرار خواهد گرفت.

چکیده [English]

The selection of suitable biological sample for space studies has vital importance. Plant cell suspension culture containing a homogenous population of proliferating cells prepares the proper situation to study various cell responses under stress conditions, especially microgravity. Cell culture systems in the laboratory can be performed in the two-dimensional (2D) and 3D culture models. In the 2D culture model, cells are cultured as a monolayer and show different growth and differentiation responses compared to normal conditions. While in the 2D model, cells are cultured in conditions that are similar to the normal conditions of cells and tissues in the living organisms and are used for medicinal purposes, production of secondary metabolites and biomass on a large scale. In this research, recent advancements and technologies used for 3D cell culture will be studied.
