Abstract
Title: This experiment explores the effect of effect of Wharton’s jelly mesenchymal
stem cells (WJMSCs)-conditioned medium on the HEP-2 cell line.
Background: Wharton’s jelly mesenchymal stem cells may be more useful for
cancer therapy than other adult stem cells since they are easily prepared in
relatively large quantities from the umbilical cord after delivery. This study aims
to determine the anticancer effect of WJMSC-conditioned medium on a HEP-2 cell
line after 24, 48, and 72 hours using flow cytometry and real-time polymerase
chain reaction.
Methods and findings: A HEP-2 cell line and WJMSCs were propagated. The
cultured medium of WJMSCs was collected and used to substitute the cultured
medium of the HEP-2 cell line. The HEP-2 cells were assessed after 24, 48, and 72
hours. We found that WJMSC-conditioned medium caused apoptosis in the HEP-2
cell line. The percentage of apoptosis was directly proportional to time. Expression
of p53 was increased after 24 and 48 hours, but after 72 hours its expression
decreased. The expression of Bcl-2 also decreased over time.
Conclusions: It could be concluded that WJMSC-conditioned medium could be
used as an apoptotic agent against malignant cells.
