The article “A case series on safety and tolerability of human umbilical cord-derived mesenchymal stem cells on patients in Malaysia” evaluates the safety and tolerability of umbilical cord-derived MSC therapy in nine Malaysian patients over one year. The study found no adverse effects and observed significant improvements in liver function tests. The patients responded positively to the treatment, indicating that umbilical cord-derived MSCs are well-tolerated, though further clinical screening with a larger population is recommended.
