Transition of Preferred Cell Systems™: A New Era in Hematopoietic Research and Cellular Therapy

From Colony-Forming Assays to Instrument-Based Assays

In the realm of scientific research, precision and reproducibility are paramount. The legitimacy of scientific findings hinges on the accuracy and repeatability of the assays employed. This principle is especially critical in the fields of hematopoietic research and cellular therapy, where the stakes are high and the potential for groundbreaking discoveries is immense. Recognizing this imperative, Preferred Cell Systems™ has made a transformative decision to cease offering its traditional colony-forming assays and reagents as of January 1st, 2025. Instead, the company has embraced its proprietary, non-biased, instrument-based assays, heralding a new era in the study and application of hematopoietic and cellular therapies.

The Rationale for Change

The decision to pivot from colony-forming assays to instrument-based assays was not made lightly. It was driven by several compelling factors that underscore the need for more advanced and reliable methodologies.

Inherent Limitations of Colony-Forming Assays

Colony-forming assays have long been a staple in hematopoietic research. These assays involve culturing hematopoietic cells in a semi-solid medium to allow the formation of colonies, which are then counted to assess the cells' differentiation potential. Despite their widespread use, colony-forming assays are susceptible to several limitations:
  • Subjectivity: The interpretation of colony-forming assays can be highly subjective, with variations in colony counting and classification among different researchers.
  • Variability: These assays are prone to variability due to differences in culture conditions, reagents, and operator techniques.
  • Time-Consuming: Colony-forming assays require extended incubation periods, up to 14 or more days, delaying the acquisition of results.

The Advantages of Instrument-Based Assays

Instrument-based assays, in contrast, offer a host of benefits that address the shortcomings of colony-forming assays:
  • Objectivity: These assays leverage automated instrumentation to provide unbiased, consistent measurements, eliminating subjective interpretation.
  • Precision: Instrument-based assays deliver high precision and reproducibility, ensuring reliable and trustworthy data.
  • Efficiency: These assays significantly reduce the time required to obtain results, accelerating the pace of research and decision-making.
