Figure 4From: A comparison of cryopreservation methods: Slow-cooling vs. rapid-cooling based on cell viability, oxidative stress, apoptosis, and CD34+ enumeration of human umbilical cord blood mononucleated cellsAnalysis of CD34+ enumeration using ISHAGE guidelines. The results of the CD34+ cell enumeration showed that the number of CD34+ cells in the samples that were previously cryopreserved by the slow-cooling method is 44.99 cell/μL.Back to article page
