Abstract

SE PRESENTAN METODOS PARA PRODUCIR CAPSULAS DE CELULAS EN LOS CUALES UN COAGULANTE (22), QUE PUEDE INCLUIR UNA SUSPENSION DE CELULAS U OTRO FACTOR BIOLOGICAMENTE ACTIVO, Y UNA SOLUCION POLIMERICA DE MOLDEADO (26) SON EXTRUDIDOS A TRAVES DE UN PUERTO COMUN DE EXTRUSION (14) QUE TIENE AL MENOS DOS ORIFICIOS CONCENTRICOS, DE FORMA QUE EL COAGULANTE ES EXTRUDIDO A TRAVES DEL ORIFICIO INTERIOR (16) Y LA SOLUCION POLIMERICA DE MOLDEADO SE EXTRUYE A TRAVES DEL ORIFICIO EXTERIOR (18). EL METODO COMPRENDE LA INICIACION DE LA EXTRUSION DEL COAGULANTE DENTRO DE UNA BANDA TEMPORAL DE ALREDEDOR DE 10 MILISEGUNDOS HASTA ALREDEDOR DE UN SEGUNDO DESDE EL SUMINISTRO INICIAL DE LA SOLUCION DE MOLDEADO A TRAVES DE LOS ORIFICIOS RESPECTIVOS. EL SUMINISTRO DEL COAGULANTE SE CORTA POSTERIORMENTE, Y LA EXTRUSION DE LA SOLUCION MOLDEADORA SE TERMINA TANTO INMEDIATAMENTE COMO DESPUES DE UN TIEMPO PREDETERMINADO.
