The goal of this observational study is to observe stored stem cells and determine their capability to grow based on several factors. The main two factors focused on in this study are as follows:
This study is a secondary, correlational, single-center laboratory study involving the analysis of previously obtained PBSC samples at the Andrews Research & Education Foundation (AREF). Individuals who previously provided samples for a primary study that has a concluded will be reconsented for this study. No manipulation of samples will occur until Broad Informed Consent has been obtained. Upon Broad Informed Consent being granted, the samples will be removed from cryopreservation and analyzed in a laboratory setting.
Each sample's total nucleated cell count (TNC), cell viability, and proliferative potential will be analyzed. Measurements will be performed at different time intervals and the results will be recorded in a password protected system.
These parameters will be followed for each available PBSC sample regardless of time spent in cryopreservation to examine if variation in time spent under cryopreservation had an impact on overall cell viability and proliferative potential.
Following conclusion of the cell viability data acquisition stage of the study, the data will be further analyzed to determine if there are any statistically relevant correlations between various demographic factors and the viabilities of the PBSC samples. The secondary, demographic factors to be examined include the sample patient's age, sex, and race. The data analysis will determine whether these factors in addition to length of time spent under cryopreservation influenced the PBSC samples' viability and proliferative potential upon the samples being removed from cryopreservation and prepared for analysis.
