The pursuit of efficient and scalable production of stem cells for therapeutic applications has spurred considerable research into various expansion approaches within laboratory settings. A detailed comparison reveals a spectrum of options, each with distinct advantages and limitations concerning cell survival, proliferation speeds, and overall yield. Traditionally, static two-dimensional (2D) cultures have been employed, offering simplicity but often struggling with nutrient diffusion and waste removal, ultimately impacting cell density. Conversely, three-dimensional (3D) culture systems, such as scaffold-based or spheroid models, mimic the in vivo microenvironment more closely, often promoting more physiologically relevant stem cell behavior and enhanced expansion, though they can introduce complexities in harvesting and analysis. Furthermore, perfusion bioreactors, representing a more advanced choice, facilitate continuous nutrient supply and waste removal, significantly boosting cell quantities and maintaining a more stable cellular climate. Emerging technologies, like microfluidic devices, offer precise control over the cellular microenvironment, providing opportunities for optimizing expansion parameters and enabling high-throughput testing of different growth factors and stimuli.
