Human CD34+ cells (Lonza and AllCells) from all sources were obtained as viable frozen states. The age of the individuals used for the profiling and treatments are as follows: FL-CD34+ (17–20 weeks gestation); CB-CD34+ (newborns); BM-CD34+ (24–36 years old). For the generation of HSC/PROG transcriptional profiles, at least three distinct lot numbers, each corresponding to independent individuals or pools of distinct individuals (of random male or female samples), were utilized to attain maximal representation. For each biological replicate, HSC and PROG populations were sorted from the same pool of cells. Cells were stained and sorted using a BD FACS Aria II cell sorter for panels of cell surface markers and dyes as indicated below.
