Human Wharton’s jelly mesenchymal stem cells (WMSC) are derived from human umbilical cord and donor eligibility is verified and negative for HIV-1, HIV-2, HBV, HCV, HTLV-1/HTLV-2, Syphilis, CMV, EBV, HSV1/2, B19 virus and Dengue virus.

Cells have been validated for high expression levels of cell surface molecules that are present on mesenchymal stem cells: CD73, CD90, and CD105, and for their absence of hematopoietic lineage markers, CD14, CD19, CD34, CD45 and HLA-DR. The cells have also been validated for their self-renewal and multi-lineage differentiation capacities.

Cells display normal karyotype as assessed by G-banding of metaphase cells and tested negative for mycoplasma and passed the sterility test.
