Multiroute administration of Wharton’s jelly mesenchymal stem cells in chronic complete spinal cord injury: A phase I safety and feasibility study

Table 3 Wharton’s jelly-derived mesenchymal stem cell quality control parameters

	QC parameters
Cell count and viability	Cell viability > 90. Cell count: Varies according to the patient
Immunophenotyping	CD90, CD44, CD105, CD73 ≥ 95%. CD45, CD34, CD19, CD11B, HLA-DR, CD14 ≤ 2% (Figure 1A)
Gene expression	SOX2, OCT4, TERT, REX1, NES, BMP2, RUNX2, PPARG, JAG1, ICAM1, VCAM1, VIM. It was concluded that there was strong positivity in genes with Ct values lower than 29, positive in genes with values between 30-37, and poor expression in samples with Ct values between 38-40 or there may be environmental contamination (Figure 1B)
Telomerase	The result should be lower than that of the positive control (Figure 1C)
Mycoplasma	Negative
Endotoxin	< 0.0625 EU/mL

HLA: Human leukocyte antigen; QC: Quality control.
