Identificaron la nueva clase de células tras inyectar una serie de células madre directamente en la médula ósea de ratones, en lugar de emplear el método tradicional de inyectarlas por vía intravenosa. Observaron que la nueva subpoblación de células madre repobló rápidamente la médula ósea de los roedores, produciendo elevados niveles de células sanguíneas en la primera y segunda semana tras el trasplante, lo que representa rebajar a la mitad el tiempo normal de repoblación.
El descubrimiento puede tener importantes repercusiones en pacientes con cáncer y trasplantados, cuyos sistemas inmunitarios están debilitados como consecuencia del tratamiento, puesto que se reduciría significativamente su período de vulnerabilidad frente a las infecciones.
