NCT05573412

Brief Summary

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:

  • Time stem cells have spent in cryopreservation
  • Demographic factors (gender, race, age)

Outcome Measures

Primary Outcomes (1)

  • Beckman-Coulter Flow Cytometer

    Machine that provides a digital view of cells that are categorized utilizing laser light to differentiate cell types while samples are suspended in a fast-flowing liquid; will be utilized to determine proliferative potential, total nucleated cell count, and cell viability of each cryopreserved sample

    At enrollment

Study Arms (1)

All Particpants

Group contains all participants as this is a systemic review of stem cell cryopreservation techniques
