Abstract

SE PRESENTAN METODOS PARA ENRIQUECER TIPOS DE CELULAS ESPECIFICOS A PARTIR DE MEZCLAS DE CELULAS. INCLUIDOS EN LOS METODOS ESTAN EL USO DE UN MEDIO DE SEPARACION DE CELULAS DEFINIDOS DE FORMA PRECISA, UN APARATO DE SEPARACION DE CELULAS QUE INCLUYE UNA CONSTRICCION QUE DEFINE UNA REGION INFERIOR Y UN MEDIO DE SEPARACION DE CELULAS DEFINIDOS. LA CONSTRICCION EVITA LA MEZCLA ENTRE LAS PARTES SUPERIOR E INFERIOR DEL TUBO. TAMBIEN SE PRESENTA UNA TECNICA DE SEPARACION DE CELULAS AJUSTADA POR DENSIDAD UTILIZADA PARA MEJORAR LOS METODOS ANTERIORES. ADEMAS, LA INVENCION INCLUYE METODOS ESPECIFICOS PARA AISLAR CELULAS PROGENITORAS HEMATOPOIETICAS CD34+, CELULAS FETALES NUCLEADAS, Y CELULAS TUMORALES DE LA MAMA. LOS METODOS DE AISLAMIENTO SON UTILES EN DIFERENTES REGIMENES DE DIAGNOSTICO Y TERAPEUTICOS.
