Abstract
Challenging environment of space causes several pivotal alterations in living systems, especially due to microgravity. The possibility of simulating microgravity by ground-based systems provides research opportunities that may lead to the understanding of in vitro biological effects of microgravity by eliminating the challenges inherent to spaceflight experiments. Stem cells are one of the most prominent cell types, due to their selfrenewal and differentiation capabilities. Research on stem cells under simulated microgravity has generated many important findings, enlightening the impact of microgravity on molecular and cellular processes of stem cells with varying potencies. Simulation techniques including clinostat, random positioning machine, rotating wall vessel and magnetic levitation-based systems have improved our knowledge on the effects of microgravity on morphology, migration, proliferation and differentiation of stem cells. Clarification of the mechanisms underlying such changes offers exciting potential for M. Anil-Inevi, O. Sarigil, M. Kizilkaya, H. C. Tekin, and E.

Introduction
Space missions induce many changes in human health and physiology, and among many factors changes in gravitational loading is one of the major contributors to these changes (GarrettBakelman et al. 2019). Mechanical forces, including those governed by gravitational loading, act as regulatory signals that effect morphology and function of tissues (Benjamin and Hillen 2003; Buravkova et al. 2008; Ozcivici et al. 2010a). Therefore, lack of gravity causes several health problems such as bone loss (Vico et al. 2000), muscle atrophy (Fitts et al. 2001), cardiovascular deconditio
