Figure 1. Uneven early cell attachment on microcarriers. Microscopy image showing variable cell attachment across microcarriers during the early seeding phase. Some carriers show visible cell attachment, while others remain sparsely populated, illustrating how early seeding conditions can affect attachment consistency. Poor cell attachment is one of the most frustrating issues in [...]
“Why is microcarrier dissolution taking longer than expected?” Microcarrier dissolution is a key step during harvest, but delays are usually linked to how the process is handled. In our experience, when the workflow is well understood and the steps are followed properly, dissolution is straightforward. When something isn’t quite right, or the process is [...]
Microcarrier culture illustrating uneven cell seeding, where cells occupy some microcarriers and become confluent and clump, while others remain sparsely populated or empty. “Why are my cells forming clumps instead of evenly coating microcarriers?” Cell clumping is one of the most frequently encountered challenges in microcarrier-based culture, particularly when working with mesenchymal [...]
“Why are my cells sticking to the vessel when I’m using microcarriers?” It’s one of the most common questions researchers ask when working with microcarrier-based cell culture, especially with highly adherent cells like mesenchymal stromal cells (MSCs). You’ve added microcarriers. Your cells are viable. Agitation looks reasonable. Yet after 24 hours, cells are clearly [...]
Small-scale microcarrier cultures play a crucial role in process development, allowing researchers to refine conditions before scaling up to larger bioreactors. However, managing small-scale cultures requires careful optimisation to ensure reliable and reproducible results. Here are five essential tips to enhance your small-scale microcarrier culture and set the foundation for successful scale-up. Use a Non-Adherent [...]
Agitation is a cornerstone of successful microcarrier-based cell culture, ensuring uniform mixing, nutrient distribution, and oxygenation. However, improper agitation can lead to issues such as aggregate formation or cell damage. Here are five focused tips to help you optimise agitation and achieve consistent results in your microcarrier culture. Know Your Context Different cell types [...]
As the demand for scalable cell culture systems increases, microcarrier cultures have become a popular choice for bioprocessing and tissue engineering. However, achieving strong cell attachment is critical for success. Whether you’re scaling up production or experimenting in the lab, these five key tips will help you enhance cell attachment and improve your outcomes. 1. [...]
Microcarrier culture is a powerful tool for large-scale cell production, but it requires careful attention to detail to avoid common mistakes that can compromise the quality and efficiency of your culture. From seeding to harvesting, each step presents its own challenges that, if not managed properly, can lead to suboptimal results.Inconsistent Seeding Due to Poor [...]
