Abstract
Procedimiento para producir plaquetas humanas a partir de células en cultivo. Se describe un procedimiento para obtener cantidades ilimitadas de plaquetas humanas a partir de las líneas celulares K562 y KU812, derivadas de leucemias mieloides. El procedimiento se basa en el tratamiento con estaurosporina a concentraciones 50 a 100 nM durante 3 a 6 días. Las células pueden crecerse en suspensión y las plaquetas pueden ser separadas de las células por métodos estándar. Las plaquetas son reconocibles morfológicamente y comparten características bioquímicas y ultraestructurales con las plaquetas aisladas de sangre. Se puede obtener así una preparación de plaquetas humanas a partir de precursores celulares genéticamente idénticos y libre de otros productos biológicos de origen humano. Pueden ser usadas para fines analíticos como servir de estándar en ensayos plaquetarios biológicos o bioquímicos.
