Sharing reagents is of self-evident value in life science research, however, primary cell populations often do not cryopreserve well or can require extensive preparation by collaborators, making shipping difficult. Here we report an evaluation of different conditions for the storage shipment of mouse bone marrow (BM) cells that would best preserve the number, viability, and frequency of different hematopoietic lineages, as well as functionality of progenitor populations. Bones were either crushed to release BM cells or stored intact in one of three media: Phosphate buffered saline (PBS) supplemented with 2% fetal bovine serum (FBS), Plasmalyte, or RPMI at 4°C. Cell numbers, viability, phenotype, and functionality were assessed 16 hours and 40 hours later and compared to freshly prepared samples. Whereas BM cells stored in suspension for 16 hours and BM cells kept in bone for 40 hours suffered major losses in cell number, hematopoietic lineages that were kept in the bone for 16 hours had only minor differences compared to fresh cells. With no significant differences among the different media used, intact long bones stored in media, Plasmalyte, or PBS 2% FBS for up to 16 hours provided a reasonable means of preserving bone marrow cell populations.
