The pursuit of efficient and scalable production of stem cells for therapeutic applications has spurred considerable research into various expansion techniques within laboratory settings. A detailed comparison reveals a spectrum of options, each with distinct advantages and limitations concerning cell persistence, proliferation speeds, and overall yield. Traditionally, static two-dimensional (2D) systems have been employed, offering simplicity but often struggling with nutrient diffusion and waste removal, ultimately impacting cell concentration. Conversely, three-dimensional (3D) culture systems, such as scaffold-based or spheroid designs, 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 numbers and maintaining a more stable cellular atmosphere. Emerging technologies, like microfluidic devices, offer precise control over the cellular microenvironment, providing opportunities for optimizing expansion parameters and enabling high-throughput evaluation of different growth factors and triggers.
