Conventional assays for hematopoietic progenitor cells (HPCs) require long-term culturing, a labor-intensive procedure, and technique proficiency. We aimed to develop a high-throughput method to determine frequency of quiescent primitive HPCs by a combination of the micro-multiwell plate and 5-fluorouracil (5-FU) treatment. The micro-multiwell plate was made of a silicone sheet with a 6 × 6 array of 1-mm diameter holes and a glass substrate. To enrich primitive HPCs in a CD34 population, CD34 cells and stromal cells were applied to micro-multiwells and cultured in the presence of 5-FU for 2 days. The quiescent primitive HPCs that survived after 5-FU treatment were then expanded with cytokines in the absence of 5-FU for a further 10 days. After culturing, cells were immunostained and the number of primitive HPCs in inoculated CD34 cells was estimated from fluorescent intensity for each well under a stereoscopic fluorescent microscope. The frequencies of primitive HPCs correlated well with frequencies of cobblestone area-forming cells for two CD34 cell lots. Our method allows high-throughput screening for primitive HPCs in CD34 cells.
