The invention provides a human umbilical cord mesenchymal stem cell injection, which is composed of human umbilical cord mesenchymal stem cells and a cryopreservation liquid. The cryopreservation liquid is composed of human serum albumin, clinical dimethyl sulfoxide and a compound electrolyte injection. The living cell density of the human umbilical cord mesenchymal stem cell injection is controlled at 0.5*10<6>-2*10<6>/ml, so that the cell viability of the human umbilical cord mesenchymal stem cell injection after cryopreservation and resuscitation can still reach 90% or above, and the treatment effect is facilitated; the content of the human albumin and the content of the clinical dimethyl sulfoxide are controlled to be 3-20% and 5-10% respectively, so that the human umbilical cord mesenchymal stem cell injection can be directly used for injection, can still be safely used after being cryopreserved for at least 72 hours, and is beneficial to achievement of a good treatment effect. The invention also provides a preparation method of the human umbilical cord mesenchymal stem cell injection and application of the human umbilical cord mesenchymal stem cell injection in treatment of liver failure.

The present invention derives from the unexpected finding that necroptosis is a novel biomarker and target for therapy in patients with liver failure such as acute liver failure (ALF) and acute-on-chronic liver failure (ACLF). RIPK1, MLKL or RIPK3 can be detected and quantified in serum or plasma, and used as a biomarker for outcome in ACLF and other diseases involving aberrant necroptosis. By antagonising RIPK1, MLKL or RIPK3 many of the unwanted consequences or symptoms of acute-on-chronic liver failure (ACLF) may be reduced. The present invention utilises these findings to identify and provide antagonists of RIPK1, MLKL and RIPK3 that may be used in the treatment or prevention of ACLF. The present invention utilises these findings to identify and provide antagonists of RIPK1, MLKL or RIPK3 that may be used in the treatment or prevention of aberrant necroptosis in the kidney, brain, liver or other organ of the body.

Methods and kits for characterizing liver damage in an individual are provided. The methods employ the use of immune analytes as biomarkers for detecting liver damage and predicting the likelihood that an individual suffering from liver damage will experience life-threatening liver failure. Concentration values for serum albumin and other identified immune analytes are obtained or determined from a blood sample taken from the individual. The obtained concentration values are then compared to corresponding concentrations from individuals having a healthy liver. By comparing the concentrations, an individual's likelihood of developing life-threatening liver failure and needing a liver transplant within a given time period (e.g., 6 months) can be identified.
