Un método sencillo para el aislamiento y cultivo de hepatocitos primarios de Salvelinus leucomaenis (Charr manchado)
El salvelino (Salvelinus leucomaenis, S. I.) es un pez anádromo ajustado de aguas frías, distribuido en el Extremo Oriente. Anteriormente hemos informado de la secuencia completa de ADN mitocondrial de los caracteres manchados de blanco (l. S. imbrius y S. l. Pluvius) en Japón.
En general, los hepatocitos de peces útiles para el estudio de los peces celular y bioquímica. En este estudio, aislamos hepatocitos del hígado y charr moteado blanco y utilizamos métodos básicos, como las enzimas digestivas y la centrifugación baja, para analizar los mecanismos moleculares implicados en las respuestas celulares específicas. Los hepatocitos aislados pueden cultivarse a 5-20 ° C pero no a 37 ° C. La morfología de Los hepatocitos se han visto alterados de forma dependiente de la temperatura.
Las propiedades de los hepatocitos son similares a las de los peces vivos. Además, la tasa de proliferación y daño de los hepatocitos aislados depende de la concentración de suero bovino fetal en el medio de cultivo. En conjunto, estos estudios demuestran que este sencillo método para el aislamiento y el cultivo de hepatocitos de peces blancos El charr moteado puede ser útil para el estudio de la bioquímica celular y otros.

Un modelo de cultivo celular en 3D identifica la inhibición de p53 mediada por Wnt/β-Catenina como pasos críticos para la regeneración de hepatocitos humanos
El hígado es el órgano que se regenera. Mientras que los hepatocitos maduros en un estado de homeostasis en gran parte silenciosa, después de la lesión, que rápidamente entran en el ciclo celular para restaurar el tejido dañado.
In rodents, various models of injury has provided important insights into the fundamentals of molecular regulate hepatocyte proliferation activation silent. Sin embargo, se sabe poco sobre los mecanismos moleculares de la regeneración de los hepatocitos humanos y los métodos experimentales para ampliar los hepatocitos humanos primarios (PHH). Aquí, el modelo 3D esferoide de PHH establecido para la regeneración de los hepatocitos y los estudios integradores de análisis multiómicos de lapso de tiempo mostraron que después del aislamiento de los indígenas adquieren Fenotipo regenerativo del hígado PHH, como se observa in vivo en la hepatectomía parcial.

Sin embargo, la proliferación es limitada. Mediante el análisis de la actividad promotora de los patrones globales, se estima que la activación de la señalización Wnt / β-catenina y la inhibición de p53 es un factor importante que se requiere para la proliferación de los hepatocitos humanos. validación funcional reveló que la activación de la señalización Wnt a través de señales externas por sí sola es suficiente para inhibir p53 y la proliferación de la inducción de su objetivo PAI1 (SERPINE1) y conducir la proliferación de> 50% de todos los PHH.
Description: The liver fulfills many vital processes in mammals. It is the central organ of energy metabolism, biotransformation of xenobiotics, and synthesis of plasma proteins under physiological and pathophysiological conditions. Primary human hepatocyte culture is an important experimental model for the study of liver specific function. Propagation of human hepatocytes is critical for gene therapy, cell transplantation and clinical liver support systems. In appropriate culture condition, cultured human hepatocytes proliferate and maintain differentiated hepatocyte function such as the synthesis of serum proteins. HH from Gentaur Research Laboratories are isolated from human liver. HH are cryopreserved immediately after purification and delivered frozen. Each vial contains 1 x 10^6 cells in 1 ml volume. HH are characterized by immunofluorescent method with antibodies to albumin, cytokeratin-18 and vimentin. HH are negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast and fungi. HH is not recommended for expanding or long term cultures since the cells do not proliferate in culture.

Description: The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human HGF. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human HGF. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Human HGF, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Human HGF in the samples is then determined by comparing the OD of the samples to the standard curve.
